Proud Armalite owner here.
I got my first rifle at 18. Armalite M15A4 11.5". In these days in Canada there was no RRA, Sabre, CMMG, Stag. There were Bushmaster 16" hbar, overpriced Colt and Armalites. I wanted a 11.5" so I went Armalite. Never regretted. It went from a standard AR15 w/ carry handle to the tacti-cooled beast it is now.
That's gen III. Gen IV has ACOG TA31F instead of TA33-R8. And the MRD is on a DD 1 ocloak mount instead of on the top of the ACOG (Much better cheekweld). I'll need to post updated pics.
Latest addition is the big bertha.
Armalite AR10T 24" of pure win.
The SBR has close to 10K rounds through it and never jammed/malfunc/etc. Fit between lower/upper is pretty good. Not ultratight but not loose either. Both are sub-moa shooters all day long. Both have the Armalite 2stage NM trigger. Sadly both are restricted in Canada (can't hunt/carry) and limited to 5 rounds (you can clearly see the rivet on the mags).
