Excellent Kit, Primary Arms Rocks.


I must say that Primary Arms is excellent to buy from. The customer service is great, sending out the order was fast, and I have not found a company that sells the same product lower than PA. The Del-Ton Upper kit was excellent and I placed a Mega Arms stripped lower and my customer was elated the way it preformed. You could not ask for a better build for a less expensive cost. I just ordered another one and will continue ordering from Primary Arms.

So far so good


Excellent value. Shipping was lighting fast and item was exactly as described. This is my second positive experience with Primary Arms and I will do business with them again in the future. If you're looking for a way to build an AR-15 on a budget you will not be disappointed here.

Perfect first AR, amazing bang for your buck.


I purchased this as my first AR-15. I built it on an Anderson lower. It has worked great so far. All the parts went together quickly and easily. Everything fit perfectly, and looks and feels to be quality. It now has about 250 rounds through it with zero malfunctions. Accuracy seems great, although I haven't shot it past 60-70 yards. I was very pleasantly surprised with the trigger. It breaks clean and feels to be about 5lbs. The mags drop free, last round bolt hold open works every time, it's all good. <br><br>If you don't know much about AR-15s, or don't feel like spending hours and hours learning all you need to know to "build" a rifle, feel confident that this kit plus an Anderson lower will yield a solid rifle that works. <br><br>This is a ZERO REGRETS keeper. I think I'm all in for about $530 with the Del-Ton kit, the Anderson lower, the Aero sight, 3-30 round mags, and the transfer fee.
