I bought these for my GEN 4 pistols and have loved them ever since. I prefer the dimpled pin as it just gives a more positive fit to my roll-pin punch tool. I went with the Nitride set on for my G17 GEN 5 and they fit great. They're a little dry after opening the package so I gave them a thin coat of oil before installing.

This is not the most expensive BCG I've purchased but it easily matches that Lantac model in very detail. The Fit & Finish of this CMC 308 BCG is incredible. I do agree with another reviewer that the Nitride coating is somewhat dry feeling. From my experience, most BCGs need that thin layer of lube so it cycles cleanly and this model was no exception. This massive BCG matched up perfectly with my Criterion 16" Chrome-Lined barrel. This model is little more expensive than other similar models but its enhanced design is what got my attention. I also watched a few reviews of the CMC 5.56 BCG and its performance also reinforced my purchase. FWIW, I'm also using a CMC Gas Tube, CMC Gas Block and now a CMC BCG. All of these components are extremely high quality. I couldn't be happier.

Okay this handguard wouldn't be my first or second choice but in this year of extremely limited options, this model turned out to be a pretty nice compromise. It's VERY easy to install and comes with a torque wrench for the included barrel nut. This nut mated with my Aero Precision M5 upper receiver perfectly. The barrel nut does require timing so that the gas tube can fit correctly. Contrary to the other reviewer who said the handguard required fitting, that is not the case. I simply used a pic rail scope mount to line up the receiver and handguard pic rails BEFORE tightening the handguard. This will insure proper alignment. The finish on the handguard is a matte black but it has been applied perfectly. The handguard was a bit dusty upon opening of the package but it easily wiped off. The handguard itself is very lightweight despite the full-length pic rail. It's also very strong. The overall feel is really good and I didn't find any 'sharp' edges on the pic rail. My only negative (which I took off a star) is that the barrel nut is not covered by the rail. In fact, there's a slight gap that exposes the barrel nut -- which is more of a cosmetic issue. That being said, it's an effective design that works to my satisfaction.
