Does this include the pins to secure it to the lower assembly?
Pat R on Jul 31, 2018
BEST ANSWER: No, it doesn’t include the take down pins. That should already be on your lower or you can purchase separately. They don’t cost much for the set.

Nice but
Great deal but looking at some of the user pics, I didn't think it was legal to put a forward grip on a pistol. That one of the guy shoulder firing while holding the pistol grip, I think your treading on dangerous ground fella.

Shoots perfectly
Loud -- as expected. Not choosy about ammo -- steel, aluminum and brass shoot without any issues. Have run around 300 rounds through it so far with no misfires.

8.5” 556 NATO UPPER REVIEW
Runs as expected. I have not had any issues with it. I am running a “H2” buffer which is near double the weight of the standard carbine buffer in order to slow the weapon down. It has functioned 100% as it is supposed to. Lube that bad boy up and it will run. Make sure you’re ear protection is on good.
As long as you run the heavy buffer,“H2”. This package runs just fine.Great close-mid range platform

Compact and LOUD
Perfect fit for my PSA Pistol lower. Muzzle brake with BMD worked well with the short barrel. Armaspec stealth recoil spring carbine cycled 200 break-in rounds without any issues. Did I say it’s loud!

Cool
The hand guard which came with it cracked first time out ended up replacing it with a quad rail.
