Pws mk111 mod2 - Primary Weapons Systems MK111 MOD2-M, .223 Wylde, 11.85 in Upper Receiver

What can I say better that hasn't been said before about Primary Weapon Systems? By far the best company out there manufacturing quality products such as gas piston uppers and lowers. I paired the PWS MK111 MOD-2 Upper (11.85in) up with my Factory PWS MK1 MOD 2-M Pistol Lower and have shot around 600 rounds so far of brass 5.56 Nato (Winchester, Federal, PMC) with out any malfunctions, jams, failure to feed, etc., using a Trijicon 1.5x16 TA44 ACOG Scope and LT105 QD Mount. I have yet to shoot it suppressed and look forward to it! This is my first PWS product, and I am very satisfied with my purchase. It is a little pricey, but I'm not complaining! You get what you pay for. I own 3 other company makes of gas piston uppers and none compare to PWS. In my opinion, I would say the MK111 Mod-2 Upper (11.85in) is definitely the go to length for reliability and accuracy in a small package when shooting unsuppressed/suppressed in any situation either for target, self-defense or tactical situations when needed.
