Excellent Product! Makes Installation and Upgrade Easy!
by Danny -
This product made it super easy to install the both catch, and has performed flawlessly through many rounds. KNS's customer service is out of this world. They were really accommodating with a request for extra c-clips (I needed to upgrade my bolt catch). Shipped the same day for a tiny fee.
Great product!!
by Jon Reese
Fits great, takes away the hassle of that pain in the butt roll pin! This may not fit every lower, for the majority they will fit. It is well worth the cost to avoid the hassle!!
KNS Retaining Pin

I have installed these on 5 rifles, 3 S&Ws, 2 on Colts. They are like Primary Arms fast shipping, THE BEST! Perfect fit on all 5.
Again and again, great!

Have installed well over 20 of these on rifles. I've never once had one come off in competition or training. If you apply locktite with needle to divots on pin for the c-clip you get an additional level of security (use magnifier for those with poor eyesight).
Needs better c-clips
by Jackson -
C-clip is way too soft. lost the first one, second and third both bent open instead of clipping to the pin.
Say Bye Bye to Painters Tape!
by Joshua -
One of my favorite parts when building lowers. I actually use an old set of surgical clamps to snap them into place because the retaining clips are SUPER SMALL! I also do inspect it after i shoot and I have never lost a C-clip yet.... I hope I didn't jinx myself just now...
Love it!

Excellent and innovative product, like some of their other newly patented parts. This pin slides in by hand like butter, and the clip retainer is easily attached by using a tweezer to place it and then snap in. Under a minute job!
Great product, better if there was a length specified.
by Gerald -
Looks like a great idea, that eliminates the risk of scratching a lower. Yet does not fit into "pre-ban" Essential Arms cast lower. The pin is too short. Would be nice to have a length spec to check before ordering.
Great Product. If you have extra money use correct ones on your trigger pins as well.
by Justin
Great product. However there is special set of punches in which the backs have a shallow hole drilled into it. This is done so you can put the spring pin in to get it started and drive it almost all the way in. Keeps you from slipping or jumping off. Then opposite side of the same punch has a special dimple that sits in the middle of the pin so when you drive it home flush, it will not slip off. Also about a quarter inch in from either side has a rubber section molded on so if your doing other jobs in a tight space the sides of punch will not leave any markings. As far as those pesky little half moon retaining clips if you look up spring half moon retaining clip installation/removal tool. You will find something that looks like a punch kit but is flat on the end with a bevel and a slice down the center. All you do is insert back end of clip into the tool and then push it on. To remove go to the open side of half moon retaining clip push tool against the clip and it will pop right off.
What a great idea
by Seth -
It really goes on easily to Ruger and Spike's lowers. I sed it through a genuine Colt bolt catch without a problem. (I don't know why someone would downgrade this because their rifle is out of spec!!??!)
There are a few install ideas here. I used a roll pin starter (hollow) that was slightly smaller than the OD of the c-clip. Wrapped in masking tape. A very easy push for the clip to get on.
