great pistol upper receiver
went from 10.5" barrels down to this 7.5" barrel with no regrets. makes the gun much easier to handle, a whole lot lighter and the slim keymod guard really makes the gun easy to hold and operate. fires well, over 200 rounds of brass case and not a single misfire, jam, ftf. cycles well, no noticable recoil the gas port is perfectly balanced for this configuration. i can see why its sold out fast, better get yourself one as soon as you can. for the price you wont get a better pistol upper
