  • DESCRIPTION
  • REVIEWS
Complete upper assembly needed to transform your standard AR into a 50 round, FNH 5.7 powerhouse! Top-mounted magazine, not included, holds 50 rounds to allow for straight-line, lower profile, and no extending magazine to interfere with prone shooting. The clever design ejects spent casings down the magazine well, eliminating flying brass and hot cases going down shirt collars. The upper receiver and rails are precisely milled from a monolithic block of 7075 T6 aircraft aluminum, and will accommodate any style of sighting system. Features an ER Shaw 16" barrel with flash hider, no gas system to get fouled which makes maintenance a snap!

"I was apprehensive about this item but the more I thought about it the more I thought it was pretty useful considering it holds 50 rounds of ammunition in such a compact rifle. Very accurate and dependable. The magazines are a little tight but they loosen up after a few insertions. The wife and kids really prefer shooting this rifle than anything else."

"This is a great addition to any AR weapon system. Fits nice and tight. Action is smooth and crisp. The picatinny rails on the side DO NOT allow the use of accesories with the magazine attatched, but the lower rail, sight rail, forward rail and the rails in front of the magazine are easily used. Very happy with the system overall."

"Easy to mount with complete, accurate instructions included. Unlike the P-90, the magazine must be aligned without any assistance from a magazine guide and takes a good second longer in magazine changes to make sure magazine is seated correctly, otherwise rounds jam immediately and require a rod down the barrel to poke the round out of the chamber or pliers to grip it and remove it. (Don't ask me how I know.) I love this thing - it is the perfect companion for the P90 and the FN pistol in 5.7x28mm."
