Sent me a used one. Package said was opened for website picture but package was damaged. Have not tried it yet so not sure how it works. Will not purchase again.

It's okay to plink with but the magazines are hell to load and won't hold 25 without acting up so I just put 20 rounds in them. The typical shell casing jamming in the charging handle happened once every mag full. I ordered the fix from bore buddy. Dumping a full mag seemed to work better than squeezing off one at a time for some reason. Overall I guess I'll hand on to it just for the versatility aspect.

Good value, lots of fun!

I bought this item about two weeks ago and took it to the range to try it out. It worked flawlessly right out of the package, no miss feeds or jams, and I wasn't using top grade ammo. Accuracy was pretty good, it was just a lot of fun to shoot, ran though 200 rounds no problem. Only draw back was the mags are a little hard to load, they are 25 round mags but the last five rounds are hard to get loaded, I ended up only loading 20 in each mag and that worked well. Over all a good deal for the price.

Sometimes things do work like they should.....

Works great after a short break in period. I had a couple double fires in the first mag or 2 but then it cleared up. I was using a BCA upper with a 7.5 inch barrel and it fit and functioned fine. The whole rifle, upper and lower were new with less then 50 rounds through it. The hammer spring is pretty heavy accounting for the double fires I believe. This bolt also fits fine in my PSA upper. The bolt I received didn't have the brass chamber adapter, it was 1 piece stainless instead, and I'm good with that. I'm really happy with the quality of CMMG's converter, seems really well made. Primary Arms prices are good and ships fast and are good to deal with.

Great product and outstanding customer service!


I started off with a bad experience with this kit. The 25 round magazines would only load 12 to 14 rounds before jamming and not allowing more to be inserted. I contacted Primary Arms and they said they hadn't had anyone complain of that problem and to send it back to them and they would exchange the kit. They received my return on a Friday and they had a new one out the same day. I received it on Monday and immediately headed to the range. Absolutely no loading problems. The mags loaded 25 rounds easily and the conversion ran rounds through my AR flawlessly. We dropped it into my son's AR and again did not have a single problem. Hundreds of rounds later, no problems what so ever. I don't know why I got 3 bad mags initially but problem fixed. Big thanks to the guys at Primary. You've won by continued business.

Worth the Price of Admission

This functioned well in a 5.56 PSA upper with a carbine length gas system and carbine buffer and spring. Worked with both 36 and 40 grain 22LR rounds.

Too good to be true!

A friend of mine let me try his because I was a little skeptical on how it works. WOW! Definitely worth the money. Now that I'm getting my nephews into shooting, this really eases the pocket book. Read the instuction because they're right, They will not function well with straight hammer. Would definitely recommend.

Great, definitely loads for fun!

This works great. Put it my M&P15 flawless, put in the PSA not a problem. Copper, lead, and even the polymer coated feed through with out a problem. Had hours of fun for very little $$

Getcha one, you will love it....

As always PA delivered, can't go wrong with this conversion kit, smooth as hell, and simple as pull one bcg out and insert one in, first 3 mags dumps only one hiccup, prob the ammo, I definitely reccomend this.... you won't regret it...

Every AR owner should have one.
