Works good

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.
