subgun24 Posted June 13 Report Share Posted June 13 Question for anyone out there who is familiar with the Steyr Aug. I have a Qualified Manufacturing Steyr Aug sear and want to put in into a Steyr Aug chambered in 9mm. What is the best host gun setup for this?

eMGunslinger Posted June 13 Report Share Posted June 13 Doesn't really matter you're going to buy a 556 gun and the conversion kit, then you are going to have to figure out if the carrier has antibounce rounds and a few other things that no one seems to do when working on AUG's.

bauerdb Posted June 13 Report Share Posted June 13 (edited) It's complicated. The new 9mm kits that Steyr USA sells has the ejector on the pack. That isn't compatible with a sear. You will have to find the older mag adapter (kit) that has the ejector on the mag adapter. You will also have to use the old-style magazines that are discontinued. The 9mm carrier already has the anti-bounce rods installed. You would just need to change the cocking piece from semi to the full auto version. Believe me I get it. It is cool to have all the different hosts setup for your sear, but it really isn't worth the cost and hassle of setting up a 9mm host. It shoots about how you would think a direct blowback 9mm AUG would shoot. My new host also needed Winchester 124 NATO to run without sounding choppy. I heard this is common with the 9mm FA hosts. The AUGs really shine in 5.56 and the hosts are relatively cheap. Steyr USA also sells the 300 BLK barrel.

BPinFL Posted June 14 Report Share Posted June 14 Begging your pardon Sir, but I only shoot my AUG sear gun in 9mm! Always suppressed, It's a great platform for 9mm subsonic. To each his own. BP Quote Link to comment Share on other sites More sharing options...

These are all German hosts built on HK94s and SP89s by TSC Machine. You reminded me the worst aspect of the 9mm blowback AUG. It is dirty. The piston 5.56 AUGs are so clean you can eat off of them.

MPFiveO Posted June 14 Report Share Posted June 14 I would contact Pete Athens at PJs. He helped me out with my 5.56 AUG and Qualified sear. He is the all knowing AUG Guru. Just keep throwing money at it and you'll get a fantastic running machine http://www.pjs-steyraug.com/ Quote Link to comment Share on other sites More sharing options...

So you would be at the mercy of making your own ejector and/or sourcing an old-style adapter kit and magazines. Quote Link to comment Share on other sites More sharing options...
MPFiveO Posted June 14 Report Share Posted June 14 Well, that's interesting. I'm not planning on converting my AUG to 9mm so I'm not really familiar with the different generations of 9mm kits though I know there are several. If Pete doesn't have it and can't do it then one is truly flying solo on that project. AUG stuff isn't cheap and discontinued AUG stuff is at the mercy of the free market.

bauerdb Posted June 14 Report Share Posted June 14 (edited) The 32 rd MPI 69/81 magazines ride low in the 2nd gen adapter. I modified the locking tab to work. You get an extra 7 rounds over the 25 round mags but lose BHO. Edited June 14 by bauerdb Quote Link to comment Share on other sites More sharing options...
MPFiveO Posted June 14 Report Share Posted June 14 So, according to the links you posted, the least expensive one is going to set you back $3200 and change. I can think of a lot more desirable ways to spend that kind of coin on gun accessories. I'm very thankful to be blessed with the collection of Subguns I own and not feel like I have to shoehorn something into one of my guns to get more enjoyment out of it. I've never shot a 9mm AUG so I might be missing out on something, but in my mind I feel like I'd much rather shoot my MP5 or Uzi and leave the AUG in 5.56 the way it was originally designed. I guess I'm looking at it like the Colt 635 9mm M16. I don't like those either. Very choppy feeling to shoot. Suppressed sucks even more because the ejection port blows crap all in your face. Come to think of it, I'm not really a fan of any blowback 9mm. I had a CZ Scorpion for just a minute. I shot one my buddy owned and dumped mine still unfired immediately. I'm fine with open bolt guns because there's a delay in the bolt opening and it doesn't pepper your face like the closed bolt blowback guns do. All of my buddies now own roller locked HK clones because, well, they like them better. CZ and now Springfield are offering their version of roller locked guns. They might be onto something. 1 Quote Link to comment Share on other sites More sharing options...
johnsonlmg41 Posted June 14 Report Share Posted June 14 MPfiveO your comparison between the 635 and the 9mm aug is pretty well spot on. Neither conversion is as good as it's original configuration. They both run fine, but both are choppy, an in the aug it's especially noticeable since the .556 version runs much smoother than an M16 generally. The new 9mm kits are great for the semi version, but modding it for a sear setup would be a ton of work and it might not work reliably. The older kits might be worth the money if they come with a bunch of mags? The whole upside here is it's the fastest F/A swap I can think of. I pull the trigger packs and swap them out in seconds. Even pulling an HK pack isn't quite as fast as the aug, and then there's the ejector swap issue. I think the crap in the face thing is way overblown. I shoot all this stuff left handed without glasses. Suppressed stuff can be annoying at times, but the fun outweighs some discomfort. The 9mm aug brass is a bit of a challenge since there's only the RH port, and I have LH bolts on 223's mostly. I bought my kits around 1200 IIRC and they are plug and play I'm not seeing 3200 worth of fun, OTOH I've spent more on more useless things. OR I guess you go $899 and work through frustration and R+D and maybe never arrive at a viable solution? 2 Quote Link to comment Share on other sites More sharing options...
localizer11 Posted June 17 Report Share Posted June 17 I cobbled together a 9mm conversion kit using new and old Steyr parts. Here's a list: New 9mm stock from Steyr New 9mm police training kit from Steyr- Keep the barrel and BCG, sell off trigger pack and plastic mag. Magwell adapter: can be found on GB Rare Original Steyr Aug 9mm MP88 Magazine Adapter - Other Rifle Accessories & Parts at GunBroker.com : 1106535283 Full auto cocking piece: Steyr AUG BCG | Shop Rifle Parts and Accessories Online | Max Arms 9mm mags: hard to find, expect to pay at least $100/mag. I bought a bunch when Steyr USA had them briefly in-stock. The kit runs well with a variety of 9mm ammo. Shoots very flat with minimal recoil - does not suppress well. I had failure to feed with fully loaded mags. Downloaded to 23 rounds and the issue went away. Total cost was about $2200 spread out over about six months to acquire all the parts.

Even at that price I'd have a hard time justifying the cost just to shoot 9mm in the AUG. Seems very lopsided when you can convert the M16 to 9mm for just a few hundred bucks. Of course, a belt fed FM-9 M16 upper costs about $2K and I have one, lol. I guess for some it's just too cool not to do certain things. I've entertained the idea of buying the 9mm M3 Grease Gun parts from Indianapolis Ordnance so that I would only have to take one caliber of ammo to the range if that's what I wanted to do. I have a kit to convert my .45 MAC 10 to 9mm and a kit to convert my 9mm Uzi to .45 ACP so I have no room to talk sense here. Quote Link to comment Share on other sites More sharing options...
