2009年11月16日 · On a range day larf, while shooting my semi-dedicated .22 upper (it has a CMMG conversion bolt installed full-time but I can drop my 15 carrier in if need be) a friend and I had a discussion about uppers, caliber versatility, ammunition commonality and the possibility of building up a Marlin 1894 as a kind of scout rifle, throwing a low-powered optic on the thing …

2010年3月5日 · While I've got to admit the choices that a rifle / carbine chambered in .357/.38 gives always has me liking it (I own a Marlin .357/.38), and while I think both cartridges make excellent all-around guns (defense, hutning, plinking, etc,), save for the novelty of it - if it were me I'd still skip plans to attempt to produce an AR-15 upper for that caliber and those cartridges …

2009年10月27日 · IIRC, the Oly guns used M1 carbine mags, so there was a mag block. Buying the upper included the mag block. About the time I heard of Taurus' "Raging 30" revolver, they canceled it.

Our test mules used standard off-the-shelf uppers (with forward assist) but the production models are billet slick-side uppers (more info below).

2017年3月24日 · He asked about just the upper receiver - not there entire URG (Upper Receiver Group) There is no 9mm-specific upper receivers - 9mm ARs use there same upper receivers as any other AR15-capable caliber. Yes, you need a 9mm barrel and bolt, but the upper receiver itself is the same as a 5.56/223, 6.8 SPC, 300 AAC Blackout, etc.

2019年3月2日 · A buddy showed me his new Oly AR about 15 years ago. The upper rocked from side to side about a 1/4". I'm not joking. I was like blaaaaaaaaaa. I'm not sure how that wouldn't affect accuracy when your irons are possibly rocking back and forth in front of your eyeballs. Now the flipside, my recce has developed some play with the lower I have it on.
