Even though I was warned by KNS in the packaging that the pin could break, I still broke it after trying to insert it several times. I'll stay with the normal pin.

Great Upgrade

Great Upgrade & Price. As usual, Primary Arms has the best quality, name brand, products at below competitor prices, with one of the fastest shipping times around and a customer service department that will stop at nothing to ensure you are not only 100% satisfied with your product but will be the first place you go without a second thought the next time you need anything firearm related. Again Primary Arms, you deserve a HUGE Thank You for your continuos and never ending loyalty and dedication to all of your customers out there. I truly appreciate you setting the standards so high. Your competitors truly need to take notes from you because anyone can have a business with customers but a truly SUCCESSFUL business is one that has customers that will return to buy again and will refer you to friends and family. I just wanted to let you know that and again thank you and for ensuring that myself, (and I am sure countless others are also), a loyal customer for life!!! MERRY CHRISTMAS!!

Quality part. Does what it's supposed to. Good fit.

Works great

by

Recently got a 7.62x39 AR pistol and it would destroy the firing pin retaining pins after every trip to the range. Replaced it with the perma pin and so far It's taken the beating without fail.

Perfect fit CMMG AR15

by

Replaced the original bent cotter pin in a CMMG AR15. Nice fit. Moderate pressure to fully seat.

Works well

by

Very consistent tension, the cotter keys always seem all over the place, some are loose, some are tight, some don't line up real great. These fit right, and fit the same every time, picked up a couple more.

broke on install

by

prongs broke off on the first attempt to install in my anderson bcg.

Worth the few bucks for your firearm.

My first time disassembling my AR's BCG was the first time I ever broke the stock retaining pin. This KNS is wonderful! I've taken the BCG apart dozens of times and it hasn't broken yet. About to buy some more as backups.

The good and the bad

by -

Broke on initial install. Very disappointed with this product too brittle. As always Primary Arms customer service handled this problem without hesitation. Thank you again for the awesome customer care.

Worked great in my

Disappointed

by -

This is the only KNS product that I can’t get behind. Broke 3 going in and 1 coming out. Still have some left but going back to the old cotter pin. Sometimes they take a little finessing but always work and if you have to throw one away it doesn’t cost as much.

Breaks easily and not worth the cost.

by -

Purchased two of these to replace difficult pins, sad to say they don't cut it. I tried them in three different BCGs,( Spikes, Odin, PSA) and the only one it worked easily in was the PSA ( was actually loose), one ended up breaking while putting it in the Spikes BCG. For the price of one you can get more than 10 of the standard pins.

Not what they once were

by -

Junk. Broke on installation. I have one of these I bought years ago that has been flawless. Sadly, it seems the quality has fallen big time. Not even worth the hassle to return it.

Nice solid retaining pin for your BCG

When following the proper installation instructions it goes right in no problem. Shot hundreds of rounds after install still in one piece.
