Top knot AR upper
by Anh Ly
It almost look like my SIG 516 upper. Well build with 4 QD slots for sling attachment, MLok all around the 15” free floating hand guard and the finish is beautiful.
<br>It is well worth more than $500 compare to what I paid at PA. What’s a bargain 👌
Excellent value, great product!
I bought this assembled upper on sale and can't be happier! I bought a set of Daniel defense sights and sighted it in at 100 yards. Was able to stack rounds eclipsing each other with PMC bronze .223 55 grain ammo. Also running a lightweight bolt. Great buy! If your on the fence don't hesitate.

Excellent quality and appearance for the money. Prompt and friendly customer assistance when I needed it too! Will definitely continue to shop at Primary Arms.
