Rock River Arms AR-15 Lower Receiver Parts Kit - Single Stage Trigger

Great, fast shipping, just what I wanted

guess rock river didn't inspect it close enough cuase it was missing rear take down pin replaced by PA. also the pistol finish was dull was also replaced by PA. thx primary arms for your great custmer service.

I have bought other cheaper part kits and did get the quality that I found in this kit. All parts were in the kit to build up my lower and primary arms did an excellent job about shipping my order promptly. Spend the extra 10 bucks it's worth it.

I ordered this kit along with a forged Seekins lower and DS Arms buffer tube/stock kit to put together a lower for an Adams Arms upper I got around Christmas. The parts in this kit were well made and went together with no major problems. Once minor problem I did run into was that the pistol grip screw that came with this kit was a 3/16 allen style screw and I didn't have a long enough allen wrench to fit through the grip base. But, rummaging around in my tool box, I ran across a Torx socket that fit this screw well enough to get it tightened down properly. Other than that, no problems with the build and I went to the range today to try out my newly built lower and it ran like a scalded dog. I am very happy with the lower I put together from parts ordered from PA. Later on down the road, I will probably upgrade the trigger to a better quality one such as the CMC drop-in, but the trigger that comes with this kit isn't terrible.

l ordered the same part from my local store and still is not in. Good prices and ships quick.

Primary Arms delivered as advertised. The lower parts kit kit was complete and was sold at a fair price. I placed my order at 7:00 PM on a Sunday evening and I was notified by e-mail at 9:00 a.m. Monday that my order was in the mail. They have outstanding customer service and a good selection of parts and supplies. I placed a second order from them last week and it came in todays mail. I will be doing more buisness with them in the future.

Quality parts, assemble well would buy more in future.Fast shipping

Received this within 5 business days. Tracking was easy. The overall procedure of purchase was easy. My billing and shipping address were not the same and they even called to verify that it is ME making the transaction. They are always there when you call.

sitting in the safe waiting on some stuff to come back from adco but have one in my RRA already and works fine

Smooth when I squeeze the trigger.
