    Took a gamble on this kit and I’m glad I did. Assembly is extremely easy if you have the right tools and some experience in building AR platforms. Even got some upgraded parts with kit. Took it out and it cycled flawlessly. 147 brass and 115 steel case ammo all cycled just fine. I am impressed.

    Have shot less than 50 rounds out of it. Have had 2 fail to ejects.My magwel adapter is used, and it has caused a lock up. I believe if I wear in the gun a bit it will be flawless.

    Seems to be a good quality product and has a great look after build, but did need a bit of filing on the selector detent track and selector detent itsself. I could not switch fire modes – the detent wasn’t sliding out of the selected positions. Got it working fine now with a bit of elbow grease. Only other thing is that I needed barrel nut shims since the alignment of the handguard isn’t achievable without them. They are not included in this kit. Have yet to test fire, but I’m thinking it’ll run fine. Fast shipping and seems like a great company to buy from. 4.5/5 stars probably more accurate.

    i have put 300 rounds through this now. using my 3d printed glock 9mm adapter and spikes lower, I can say I am having a blast on such a cheap budget. Super amazing kit!

    I also took a chance on this kit. First let me say the Durkin Customer Service (Lauren) is fantastic. She was quick to respond and also did a follow up to make sure the the components were delivered and that everything was working correctly. That being said, I had two troublesome issues with the parts. First the muzzle device was stripped and wouldn’t thread on the barrel. Durkin took care of this quickly and a new muzzle was sent. Second, the castle nut was not threaded correctly which stripped the buffer tube. I needed a new castle nut and buffer tube. Again, both taken care of quickly by Durkin. My issue is that this shouldn’t happen with mil-spec parts IMO. I guess with the high demand and excellent pricing they might have to select new suppliers other than what they normally use. After those two hiccups, the build went together great. Two boxes of 9mm later and the gun cycles flawlessly. I would have liked to have the LRBHO feature but it was not included on the upper or BCG. Not a show stopper for me.
