I built this one tonight (actually repurposed a plain Jane AR). The upper came from RightToBear. Some things I prefer:
1. MILSPEC lower with magwell insert, so I can go back to 5.56 or 300 Black or whatever I want. Esp. if this is an SBR.
2. Colt style mag. Glock mages are not made for an AR magwell!!! Colt style locks open on the last round without any added do-dads. Colt style mags use the normal manual of arms to insert and release the mag. I can get a 32 round mag from out of state. A 10 round is pictured.
3. Slick side upper. I am not installing a forward assist that does nothing and adds weight.
4. 9mm size ejection port; I am hoping this minimizes gas in the face - we shall see.
5. Cassette trigger with a hammer made esp. for 9mm bolts. I like this CMC straight single stage trigger for faster shooting as opposed to a two-stage Geissele for more deliberate longer range shots. Yes I know cassette triggers can be less reliable but this is a range toy - calculated trade-off.
Right now it uses a 7.5 oz PCC buffer and carbine buffer spring. May switch to something more sophisticated later.
This Holosun red dot looks better than my Vortex or PA red dots. It's as good as my Aimpoint PRO. I like the micro prisms better though, but that's a future thing.
