Nice fit and finish. Easy swap from a standard ar15 upper to this AR9 upper. Definitely recommend if you’re looking for a solid ar9 upper for a build.

Great product and fast shipping.

Good price, very good design with very good machining. How ever I wish the upper and lower mated together with a bit tighter tolerances
By Tyler S.
Quick and easy transaction. Item matched description 100% accurately. Processing time was short and shipping was fast. Very reasonable pricing.
