Ratings & Reviews
Excellent build for a very good price
by Tri -
For the price, this is an excellent upper with many features. It shoots straight and durable with quality material. Good job to Primary Arms for bringing excellent pricing and Radical Firearms for making excellent upper.

Excellent upper for the money. Placed it on a Spikes lower which is just a tad loose but was easily fixed with a wedge. Thanks PA!
Barrel leaning right
by Kevin -
Shoots nice and smooth, feels nice and solid, but the barrel points noticeably to the right. It points so far to the right that my rear iron sight had to be adjusted all the way to the left to get a good center.
Bad machining. Out of spec receiver
I have bought two complete uppers and one so called match grade barrel from radical firearms. This was the most recent and last product I will buy with that name on it. The upper receiver that came with this is 1 mm thicker than any other receiver I have and customer service says the answer is to beat my sight on with a rubber mallet. The rail is so out of spec that when clamping a scope ring on the ring sits on an angle and there is a huge gap between the two.
