Very nice upper for the $. fit nice and snug to the lower. I had it in the box along with a stripped lower and a lower parts kit. They all went together without an issue. Too bad you just can't find them anywhere now!

Item priced right and makes it possible to make the use of a standard AR lower. Quick change from one caliber to another in less than 5 minutes and you are shooting cheap 22lr ammo.

Shoots great and the mags are easy to load because you can compress the spring and just drop ammo in. Only thing that would help the buyer is better description of the product. Upper receiver is composite not a metal product.
