Economical Upper Parts

by -

This kit worked and installed well. The dust cover had a slight bend which straightened easily in 3 seconds by hand. The finish is satisfactory after a clean and oil prep. For the price it is a fine kit.

Good enuf

Forward assist and all of the smaller parts looked to be of good quality despite the low price. Dust cover did not seem to match the same level of quality. It had a poor finish and was covered in dried cosmoline. Dust cover was also bent so I had to bend it straight to get the rod through. Dust cover detent also sits a little high so it takes some extra effort to close. Once everything was installed, looks good enough. 1 star for the dust cover, 5 stars for everything else. 4 stars overall.

A great upper receiver parts kit!!

All parts needed were included. Went together in a snap. Easy!!!

Inexpensive no frills parts kit that does the job.

All the parts fit well and the 'C' clip was already attached to the hinge pin.

Couldn’t use it


Bought this kit and the “e-clip” was missing of the rod for the dust cover. It rendered the dust cove useless
