Hi Kevin, Per our conversation a few minutes ago I will take the Group M2HB receiver.

Thanks for the reply. I have a cache of spare bolts I feel pretty comfortable with given my M60 only get shot once or twice a year. However putting another bolt or two on the spares pile is never a bad idea. I just sorta wanted to see some first hand reports on how they held up before buying extra "extra" spares I will probably never need in my lifetime. Granted in this game "if you snooze you can lose" so if this was a known one time and done production run deal it might be worth the risk to buy a couple before any field reports are available. I just sorta always assumed US Ord and Desert Ord were kinda one in the same thing and Bob worked for both entities. i.e just two separate FFLs in the same building/facility separated by a fence, etc. with one focused on Mil and one on commercial sales. Dessert Ord being the "commercial" arm of those sales when they choose to sell stuff (which seems to be pretty rare over the past 10ish years) My impression based of conversations with them was the Dessert Ord didn't actually make any parts themselves and they always got them from US Ord's manufacturing side whenever they did have any parts for sale. i have been fortunate to get some spares out of Desert Ord over the 15+ years I have owned my M60 and after a couple years of asking/waiting I was finally able to get a complete E6 kit from them last year. However, 9 times out of 10 if you make an inquiry on M60 parts to Dessert Ord they don't have any major wear items like bolts/op-rods/barrels/etc. for sale which always seemed odd since I just presumed the sister company "US Ord" on the other side of the FFL fence in the building had machines carving out M60 parts that both companies could sell to their respective markets. However, I guess the M60 parts supply chain mystery sort of continues. Thanks again for helping get the community new bolts as a new source was desperately needed and it will help keep folks from paying exorbitant fees on gunbroker.

Aaron, Are these new DLC bolts going to be a one time produced item or does the manufacturer plan to continue to make them going forward? Out of curiosity do you have any insight on why US Ord doesn't sell complete bolts? They must make them on sort sort of regular cadence for military orders but in my experience it is exceedingly rare for Bob to ever have any standalone spare bolts (or op rods, etc.) for sale when I talk to him. I have never pressed US Ord on "why" they never seem to have critical spares available but it seems to me like they could sell the shit out of bolts/op-rods, etc. if they wanted to but choose not to.

Looking at that gun with the M4 style receiver reinforcements and markings that don't even remotely look like any other Sendra I have seen in 20+ years, my personal take is the odds are 99%+ that its a 80% lower with a transferable serial number transfer scheme and a >1% chance that its a legit transferable Sendra M16 receiver. What I don't understand is why if you were going to illegally move a Sendra serial number to a new 80% lower (which most likely happened here) at least do a better job of it. (at least find an A1 style 80% to start with.)

Thanks for the video. As an long time owner of an RIA M60 it is interesting to hear some of these details and how actually similar these guns are and where the difference are (like the skeletonized rails) Aaron, any thoughts on the US/Dessert Ord receiver refurb/rebuild service? I have been seriously tempted to have my registered channel gun upgraded with the forged trunnion, correct rivets, etc. as the cost is actually not bad. The main thing holding me back is getting the gun to US Ord there as I really don't want to ship it but am seriously considering hand delivering it sometime next year. I would be interested to hear any 3rd party pro/cons if you have seen any of the US Ord upgraded RIA guns in person and/or how once upgraded compare to a SACO/Maremont factory gun.

For USPS Registered mail the max insurance value is $50k. However you can declare a value over this amount (like the shipper above did and declared $80k of value) but it won't mean the insured value is over the max USPS registered limit of $50k. So in this case if the M60 gets lost the shipper is going to best case eat $30k unless he has private 3rd party insurance to cover it. The unfortunate reality is if it gets lost USPS probably wont pay you the $50k insurance value either....not without a long drawn out fight anyway. Fingers crossed I hope it shows up safe and sound in the next couple of days.

It was my mistake on not asking about the tracker upfront before agreeing to buy and I was not going to welsh on a deal as I agreed to purchase before asking about including the tracker. It honestly never even occurred to me somebody would say no. My only point from recent experience is, don't assume all dealers will agree to a package tracker and if its important to you ask upfront before committing to purchase. In my experience more often than not you are on your own if something goes wrong and very few sellers will take accountability for their mistakes/issues if something goes haywire with shipment/delivery so don't count on insurance purchased by the seller to make you whole. Maybe I am unlucky but In my experience it seems to be about 1 in 5ish firearm shipment have problem with sellers not following agreed upon instructions and/or the carrier screwing up. (which is why I have gone to using package trackers) My gold medal shipped screwup experience was one of the long time dealers here on this board a couple years back shipped a machinegun regular priority mail (vs registered), without proper insurance, packaged in a thin cardboard sleeve constructed from reused cardboard box pieces held together with masking tape after we agreed on registered mail, fully insured, in a hard case. Once it showed delivered we realized the machinegun was shipped to the wrong address that didn't match the approved form, and then the cherry on top was once my dealer tracked the gun down it also turned out the seller also shipped the wrong machinegun (serial # didn't match the approved form) that then be shipped back..... If I was getting work done on my personal M60, I would lock it in a pelican with a tracker, get direct/non-stop flight to the closest airport to the receiving FFL and then personally drive/hand deliver it. Once the work was done I would fly back pick it up and take a another direct/non-stop flight home. I don't think there is a carrier I would trust with something like that and even if I shipped it to the gunsmith USPS registered mail the return shipment from the dealer would have to be Fedex since I am not an FFL.

No idea on the guys age. Its now just another eccentricity I have to be upfront about prior to actually committing to a high dollar purchase if I want a tracker in the package. In this case I committed to purchase prior to asking to put a tracker in the package as I never expected somebody to say "no". Now I know to ask future sellers prior to committing to purchase. The good news is the gun actually arrived on time without any problems after being shipped Fedex ground (uggg). The downside is the gun has all sorts of significant undisclosed mechanical issues that I am having to fix.....but that aspect isn't an uncommon issue in this market.

I actually recently had an FFL seller here on Sturm for the first time refuse to include a GPS location tracker in a high value firearm shipment. When I asked why he wouldn't allow a GPS tracker in the package I was told it was a security risk as I would be able to track the package location in detail and could then potentially steal it off the delivery truck before it got to my FFL. That was a first for me.... so just something to keep in mind that not all FFLs will allow a tracker to go with the gun.

Technically the seller (if he is not an FFL) is correct in that he personally as an unlicensed individual has no legal way to ship the suppressor (or the short barrel rifle) as UPS and Fedex won't accept firearms for shipment from individuals and it would be illegal for him to use USPS. Shipmygun via UPS also won't accept NFA firearms either. However, there may also be a component of this situation where it sold for too cheap so this is a good excuse not to complete the sale. That said he should have known this before listing that package on Gunbroker and allowing folks out of State to bid on it if he didn't have a local FFL lined up to ship this for him , wasn't willing to personally deliver it via a flight/drive to the buyer, or wasn't willing to take the risk and break the terms of carriage and ship Fedex/UPS and/or break the law to ship via USPS. As Taylorwso mentioned your best option would be to send him a waybill if you have a UPS or Fedex FFL Firearm Authorized shipment account so it would be you sending the gun and suppressor to yourself and the seller is just tendering them to the shipment hub for you. You could also legally fly/drive and pick it up in person being that you are an FFL but it might not be worth your time/effort. Good luck and hopefully you can find a reasonable solution.

I will take one as well. PM sent for additional payment instructions.

My experience is that its not the ideal platform to suppress. Is it worth the trouble....I would say "maybe".... depending upon moderating your expectations. 1. Any piston based system that directly vents high pressure gas out of the gas block for action regulation (normal, adverse, etc.) is going to be louder than say an AR15 where the gas jet is contained inside the action to a much greater degree. The AUG vents gas directly out of the barrel, into the gas plug (aka regulator) which then has a vent hole directly into the atmosphere. So from a mechanical perspective the AUG is going to have what is traditionally know as "piston pop". This is why on the Ratworx AUG specific suppressor they actually vented the piston vent into the suppressor body itself. If you use the AUG specific "suppressor" gas plug, the vent hole into the atmosphere on the suppressor setting is even bigger that the normal sized hole in the gas plug (venting more gas so as to not overdrive the gun with the suppressor attached) which can make the piston pop even louder. I am not sure why Steyr didn't restrict the entrance hole into the gas plug vs. just venting more gas out of the gas block but it is what it is. That said a suppressor still makes a dramatic difference in terms of sound moderation on the AUG even if its not the best platform to suppress. 2. Given the bullpup arrangement and where it places you face/eyes in relationship to the ejection port any excess gas that pushed back out of the chamber it becomes much more noticeable to the shooter vs. a traditional rifle arrangement where you face is much farther back. This is probably where a low backpressure style suppressor would really have an advantage. Even with a suppressor gas plug not to overdrive the action, a high backpressure suppressor still pushes excess gas out of the chamber and into your face, especially in full auto. I made a 14" pinned to 16"+ barrel via with a custom made AAC/51th/Tulip hider. I also made a custom suppressor gas plug for it as well given there is no AUG suppressor gas plug for a 14" barrel. While it looks cool and functions fine, I honestly don't really shoot the barrel much at all.

Having shot both (and owning a Shrike. There are some perceived advantages to the Shrike/MCR over the M249. 1. Weight. (This could be a pro or con) The MCR is a lot lighter than a M249. The Shrike/MCR is sub 10lbs where the M249 is 50% more at 15+ lbs. Obviously this is config dependent as well. However shooting a 12" barrel MCR vs. a Para M249 the weight difference is noticeable. 2. The MCR seems to run better when fed with mags than the 249. Not that anybody really cares...but if you do run out of belts at the range the Shrike/MCR happily feeds from mags as well. One of my buddies shoot mags through his pretty regularly once he runs out of belts. I have other M16s so just grab another gun to shoot mags. 3. Cyclic rate on the MCR is more adjustable using the gas regulator and different buffers. The Shrike/MCR has a suppressor setting as well where the 249 is generally either fixed or has a normal/adverse setting depending upon the barrel. Granted the M249 ROF is natively a bit slower than the Shrike/MCR. Maybe there is a suppressor setting barrel available now as well. 4. This could be a pro or con but the Shrike/MCR has a much better trigger (and lots of trigger upgrade options being AR pattern), has a semi-auto setting vs. full auto only on the M249, and is closed bolt operation for much better first round accuracy as the bolt isn't flying forward when you pull the trigger. 5. There are transferable Shrike's/MCR available so unless you want to spend north of 7 digits on the one transferable 249 (assuming the current owner would sell it to you) a transferable 249 is pretty much unobtanium for all practical purposes. Overall the M249 is still a more robust beltfed design, no doubt about that. The Shrike/MCR bolt over travel and ability to strip round from tight links is reduced compared to the M249. I personally run a lower power recoil spring vs. the factory OEM spring so do have stretched "shrike links" I use. I have two friends with recent (past couple of years) MCR purchases and both have run pretty much flawlessly without issue The only part I have broken in ~10 years has been a firing pin and I lost a small c-clip off the top cover at one point.

I don't know why a stripped lower would avoid patent protection. The non-detachable handgrip part you highlighted is about the mounting structure for the handgrip. Claim 6 thru 8 are specific to the SAW box style lower. 6. The receiver body of claim 1 wherein the accessory mounting structure is configured for engaging a mating mounting structure of the accessory for enabling the accessory to be secured in a relatively fixed position with respect to the receiver body. 7. The receiver body of claim 6 wherein: the accessory mounting structure includes a tapered engagement Surface; and the mating mounting structure of the accessory includes a mating tapered engagement Surface whereby engagement of said tapered engagement Surfaces limits an engagement depth of the accessory with respect to the accessory mounting structure. 8. The receiver body of claim 6 wherein: the accessory mounting structure includes a keyed engagement structure; and the mating mounting structure of the accessory includes a mating keyed engagement structure configured for being engaged by the keyed engagement structure of the accessory mounting structure. Looking at the diagrams in the Ares patent is pretty clear that Cryo pretty much copied Ares patented SAW box lower hook, line, and sinker. Now whether that hold up in litigation I don't know as I don't have a crystal ball.....but the drawings in the Ares patent compared to the Cryo lowers look pretty damning to me. Legal mumbo-jumbo aside, it would be difficult to defend that Cryo isn't pretty clearly infringing upon Ares unique design/invention for financial gain.

Thanks I was just curious as I also thinking about suppressing my Reising if/when the transfer is ever approved but was concerned about how to get the muzzle device off without damage and what an accelerated ROF would potential do to the internal components. Always curious how suppressed Reising function and if there is any bad port pop, etc. I have been working on form 1 suppressor design that would be Reising specific. Basically like a mini Salvo-12 or large Osprey in terms of shape so the factory sights would clear the top of the suppressor, with a gemtech halo style attachment collar so it could side over the factory muzzle break and lock to shoulder behind the brake (so I wouldn't have to drill the factory pin), and make it with a large blast chamber and/or a quasi flow through design to limit backpressure and increases to ROF.
