AR57 5.7x28mm Upper Kit

Lightweight, fast-handling upper receiver system
Chambered in 5.7x28mm caliber
Horizontal, top-mounted 50-round magazine (not included)
16" E.R. Shaw barrel
Monolithic block of aircraft grade 7075 T6 aluminum

A revolutionary new design that blends the ergonomics of the AR-15 lower with a lightweight, fast-handling upper receiver system chambered in the exciting new 5.7x28mm caliber. This ultrareliable unit is fed by a horizontal, top-mounted 50-round magazine (not included) atop the 16" E.R. Shaw barrel, and there's no gas system to clog or foul. The upper receiver and rails are precisely milled from a monolithic block of aircraft grade 7075 T6 aluminum. Kit includes a barrel, semiautomatic bolt, carbine buffer and manual. No FFL required.

Jams frequently.

Date:April 5, 2011

Seemed like a great idea. Purchased it and mated it to a DPMS lower. Started double feeding and firiong 2-3 rounds at a time (not good as second and third rounds the necks were straightened). Contacted mfg and was told the problem was the trigger assembly as it needs a single stage trigger. Now I have a useless upper till I aquire an older single stage trigger. I would suggest that if you want to fire this round, buy a complete unit.

This is a great product! Much better than a rimfire conversion, with more range, accuracy, and power. I can easily keep groups under 2" at 100 yards with a 4x ACOG.
It's a hoot to shoot, no recoil, blow back action stays cleaner than an AR, and all empties are ejected down the mag well for easy pick-up. Quality is excellent. A high tech upper for your AR. A must have for an AR lover.
