Had to replace the end plate

by -

This kit was fine with the exception of the end plate. It was bent, and the edges were rough. I couldn’t even get it on the buffer tube so I had to order a new one.
<br>From PA: We're sorry that you received a bad one and we'd be happy to swap it out for you.

Cheap for a reason

by -

The end plate wasn't perfectly smooth. You could run your finger around the inside and fill a lot of raised and rough areas. Because of this, it would not fit over the threads. It took alot of sanding to get it to finally fit.
<br>From PA: I'm very sorry that you had this issue. We'd be happy to swap it out for you.

Great kit

Installed this kit today and the fit and finish was great. Threads were clean, buffer weight was accurate and the charging handle clears the end plate no problem. Great, simple no frills buffer tube kit. Can't beat it for the price.

Great Value!

Very nice kit for the price. Nice threads and no visible toolmarks on the buffer tube, spring and buffer are good quality. Didn't use the end plate so not sure about it's fit or clearance for the charging handle.
