I've been shooting Hornady 110gr RN out of my 16" AR, pistol length gas system, M4. A mild charge,17.4 gr of H110 at Hornady book COL. So far great accuracy out to 50yrds (clover leaf), cycles well, no complaints in the first 250 rnds. Using 10 rnd P-mag only had 2 FTF in 250 rnds. Might have a unicorn here, but like McDonalds says " I'm loving it".
I know I'm missing the blackout boat with 110 supers, but for a cheap plinker that hits what you aim at... it's fun.
