Ryo Posted September 19, 2022 Report Share Posted September 19, 2022 (edited) Item for sale is a bullet feeding guide for the MCR, otherwise known as the Shrike/MCR feed insert. The design and current dimension for this is based on my own measurements and trial & error, but the idea came from Mark G.'s design. After many iteration of the design, I finally came out with one I'm happy with. I have test fired and had no reliability issues. A board member generously lent his original insert to me. I used it to do some comparisons to mine version. I did not do live firing on his when comparing since I didn't want to risk damaging it, however I did test it on a version I duplicated from the original and it fired without issue. --------------------------------------------- Your choice is to purchase my design, or a clone of the original. Price for one is $90 shipped via USPS. Price for two is $170 shipped via USPS. If you need a different carrier, let me know and I can let you know the price difference. Payment method is Zelle, Venmo, or PayPal (you pay the fee or pay Friend & Family) --------------------------------------------- Earlier proof of life video: https://vimeo.com/735885372 My observations between his and mine dealing form/fit/function were: My bullet guide is a bit more aggressive design to force the bullet nose up. I had done this on purpose to ensure the bullet tip would be guided more towards the center of the chamber. The fit of the original was very loose. Every time opening the top cover it would fall out. My version I added a ball detent to keep it in place. Not a big deal since you could have shimmed the original in. Note 1: My design (before I received the original insert) was actually form fitting to my top cover, but since original one was more narrower, I decided to match it. I wanted to ensure that mine would fit in all top covers. I had heard from some owners of the original insert that the fit was tight. I added the ball detent to ensure it keeps it from falling out. I tell you.. it was annoying to have to hold the insert in place when closing the top cover. Note 2: I could have done the shim method.. but it really gets tight. If you wanted to remove it, it would have been a struggle if it was tight. I did experiment with adding built in shims to file down but I found it was really tight. Plus there was no guarantee that the shim I used material would not eventually compress under fire, hence it would falling out like the original in the future. The ball detent is a bit more work and cost more to do, but it offered a great benefit. My guide section is a bit concaved in the shape to the shape of the bullet head. I doubt this makes mine better or worse than the original. The purpose was to give it enough space to not interfere with the feeding assembly. The slide ramping of when the bullet pulled into place is a bit different angle at the shoulder. The original is smoother due to how it was molded. I don't think mine will have any negative affect here, but definitely the original is smoother than mine. The original is more brittle. Due to the material it appear it could chip. The loaner I borrowed has a very minor chip due to the material going to a thin peak. I made mine a bit thicker due to that observation. Is the mine better than the original? Perhaps, but I can't tell with the small sample size of shooting. Will this fix every issue with the MCR? No it will not fix every issue of the MCR. Some of the later generation MCRs are less sensitive to feeding due to the feed plate. However with the guide, it would force the bullet head to center more towards the the chamber. How long will it last? I can't say since I have only a couple hundred rounds though my testing. After the test firing, it looked like it had little to no wear. Since the bullet was not designed to scrap and slide on the guide, I believe it should last a long time. Since this a design based off of a specific MCR, there may be some sanding or fitting required. I tried to eliminate some of that with the ball detent, but I can't guarantee the milled depth being deeper or more shallow. If you have issues, I would want to know so I can make this product better. If you have any questions, please feel free to ask.

Ryo Posted August 24, 2023 Author Report Share Posted August 24, 2023 From what I can tell is yes it fits all of them. I know there is play among different top covers so I added ball detent to deal with some play (and keep the part in the top cover when opening). The side without the detent can be filed down to make a better fit. However since I don't have every top cover, there could always be some variance. I've sold quite a few of these and no complaints so far about fit. Please PM me your dimensions of your top cover and I can double check.

VidaEterna Posted October 10, 2023 Report Share Posted October 10, 2023 (edited) I’ll take one per our conversation. Funds sent last night. Thanks. Finally got around to trying it out. I ran 30 rounds thru my MCR and no jams! The best I got out of it before was 3 rounds and a malfunction. The range wouldn’t allow green tip, so 30 55grn was all I had on me. I need to shoot it much more, but so far I’m excited again about my MCR.

Ryo Posted January 15, 2024 Author Report Share Posted January 15, 2024 I've had a couple of customers mentioned that it worked perfectly for them. One person tried to see how much of the bullet still contacts the feedramp/barrel extension. They said the bullet never scratched off the paint he had placed on the bullet, hence my guide guided the bullet into the barrel cleanly.

Hey apologies for taking so long finally got around to installing it and giving it a test run. I'm using 62 grain bullets and it seems to have cured all the problems rn. I have only put about a hundred rounds through it and have plans to do some longevity testing with various ammo. Only problem I had was the block didn't always stay in my top cover think that's just my gun though. Great product I'll let you know if anything else comes up:) Quote Link to comment Share on other sites More sharing options...
Ryo Posted July 15, 2024 Author Report Share Posted July 15, 2024 (edited) Is the ball detent on the part functioning? It should put a little pressure on the side of the internals to keep it in place. If the ball detent busted, let me know. If the ball detent is working then check the internals to see if the ball detent is being pressed into the sides of the top cover. If it doesn't then your top cover is milled wider than normal for that slot. Really glad it helped out with your problems. I always like to hear feedback on items I designed. Thanks.

Ryo Posted July 17, 2024 Author Report Share Posted July 17, 2024 Well talking with Cargoman45 about it and apparently it was falling out the first couple of times, but after shooting it hasn't fallen out. So my guess is that the detent somehow got stuck, and after it got rattle a bit from shooting, it started to work again. Sorry for the inconvenience, I know that that part falling out was quite annoying which is the original idea of adding a detent to the design. I'll be sure to test every one I sell now to make sure that the detent will retract and return to normal resting position. Quote Link to comment Share on other sites More sharing options...
