Been involved with a few short barrelled AR's - 556 exclusively, Velocity loss is incredible - no, I did not chrono the loads, dead on at 25, 12 inches low at 100, 6 inches low at 50.
Not something I was interested in, personally.
Looking at a 9mm AR to complement handguns (less variety of ammo)
Also, REALLY looking at 350 Legend.
Worked a lot putting together PSA, nothing wrong with those weapons or the company. MILSPEC is MILSPEC, period.
I did put together a couple of PSA 308s and there is no MILSPEC on AR-10, thus I've been told uppers and lowers between companies are not compatible - but I really can't verify that.
Complete bullshit.
