Great AR Pistol package. Especially at this price. Purchased two kits. Both were complete and were nice quality. Ran a couple of mags through both to ensure function. Both performed flawlessly.

Works Great

I was able to fully assemble the pistol with just my added lower and rear sight. It worked absolutely great. I drove out to the desert just to test it out and shot up a pumpkin at 75 yards. With just holding it out and standing, I'd say that's accurate enough.

Good upper, very solid. A little on the heavy side considering its only 11.5inchs. Took it to the range, it fed and fired just fine, accurate too. The barrel and bcg are chrome lined too which is a big plus for this price considering most budget builds are phosphate coated only. Reason i knocked off a star was because just like the other reviews stated the lower parts kit that came with the upper isnt complete, i was missing one of the takedown pins and pivots. Delton should double check their kits before sending them out. I got one off ebay for 5$ so its not that big a deal considering the price point, just inconvenient to have to wait to get items u thought u were going to get.

Lower parts kit not complete

I just purchased this upper and LPK. I am actually fond of Del-tons stuff, they work and cosmetically are pretty sound rifles. The only issue is the parts kit was missing a magazine release button and the other parts in the LPK are pretty rough. They have to be ground to fit in some places. A cursory search on the net will tell you the same thing. Good rifles, just lacking in the QC when it comes to their lower parts kit. My suggestion would be to order a better kit. Over all really happy with Primary arms as they dont screw around with their shipping and customer service, would gladly order from them again.

Really Nice

Another great upper from Del-Ton.
<br>Barrel is chrome lined, bcg staking is gtg,
<br>front sight is pinned correctly and straight
<br>as a arrow. Mated to my aero lower perfectly. My lpk was complete and in exc condition, comes with h1 buffer and a nice tube with foam cap. Great service from Primary Arms as usual, thank you guys.
