A Good Item But Not For DPMS

by -

I bought one and was disappointed to find that it was too short, so I called KNS. They researched it and said that it would not fit my DPMS lower and offered to take it back if I had bought from them but I hadn't. I just kept it as it would cost as much to return it to PA as I had in it.


<br>I built a carbine last weekend for a friend and used it on his Anderson lower where it fit perfectly. Will put one in my new lower.

No problems here

Works great and it's nice to have the ability to remove the bolt catch pin without much trouble. I found the best way to install the C-Clip is with a pair of tweezers, or at least get it started where it belongs and seat it with a punch. You can also use the tweezers to remove it if need be. When I first saw this item I went to my lath and made one to see just how effective it would be. Mine works but to have one that's the right color is a plus.

KNS Quality, new and testing...

I was unsure about this at first, but wanted to give it a shot. I'm not disappointed with it either. The C-Clips are a pain in the rear to get on, however it's a great fit. I'm using this on my Aero Precision Freedom lower build and it works.

Great idea, poor execution

Great idea. But, the lower does not allow the pin to slide in all the way so you cannot put the c clip on. Even if you could, it doesn't look like the c clip would have enough room to fully seet on the pin.
