I'm seeing different barrels for these kits. Do the nitride kits come with nitride barrels or no?

For what I paid, it's a great rifle.
Couldn't have asked for more. The nitride barrel was done very well, and the kit, once completed with an Anderson lower, turned out to be a well-functioning and good-shooting rifle. Purchased about seven weeks ago and already have close to 1,000 rounds through it. I highly recommend to anyone looking for their first AR.

Great kit at a great price!
For the money these kits are hard to beat. You get quality parts at a great price. I definitely recommend these kits. They even send a extra detent and spring in case you lose one while assembling it. Needless to say those come in handy sometimes. Lol

My first ar build, milled the lower and assembled, easy and accurate. Quality and function is perfect, best first experience with a firearm. Palmettostatearmory sells quality and customer service. I'll be back.

This was my first AR build. I paired it with a Ruger lower. Everything went together very well. I appreciate the very fast shipment form PSA. I received the very next day after placing the order.

nothing but quality
The assembly was a breeze. I would recommend this to anyone, even those who have never tried to build their own before. Matched up perfectly with the PSA lower. Functions like a Swiss watch....perfectly!!
