"Every other round does not extract. Bolt does not close. I tried it with two different lowers; one with a standard trigger, and the other had a Chip McCormick drop in trigger. The upper should come with a forward assist. I had a lot of miss fires because the bolt was not fully closed. I wish I bought something else. It shot two in a row, once. I have lost my confidence in CMMG products."

"Was sorry to see Steve had issues with his upper. Just put 150 rounds through mine today and it cycled and closed flawlessly, using CCI Mini Mags and Federal (I can recall the variety). I did have issues with Remington FTFs late in the session, but attribute this to the ammo. Four bullet review overall. Likes: ease of breakdown, reliability. Dislikes: no forward assist (with Steve on that one), Picatinny rail on gas block sits lower than flat top rail and I had to dial a Magpul front post up to the last thread just to keep from shooting over the backstop. Other than that, solid plinker. Those Missourah boys may have a winner on their hands."

"Called CMMG on the low profile front sight mount - for $10.00 (and postage to send the low profile back), they exchanged the front for a receiver-height mount. Quick shipping, good customer service, and fast responses from their tech team. This is a company that should be watched. I think they'll make a name for themselves."
