What do you guys think of the updated cotter pin design? I forget who makes it but was wondering if its worth 8bucks?
Thanks
The ‘updated’ solid pins are just actually like the really early design. Stay with the standard cotter pin type, they hold up well.
Are you talking about the KNS Perma Pin? They go back to the early days of firing pin, retaining pins.
I personally like them a lot. The reason is that they are made out of better materials (stronger). I have broken and bent a lof standard pins and have not been able to do so with these.

Yup thats the one, Grant are you selling them?
Grant (or anyone else),
Do you still like and use the KNS Perma Pin? I’m using it one of my 6920’s but I have only shot about 200 rounds with that AR in the last year.
For me, the standard FPRP 5 pack/$2.24 at Brownell’s works fine.
Hey Dave I used one in one of my builds but the sucker was not very tight after awhile like the standard pin and would fall out of the carrier so I X’d it.
thats actually the first thing that came to mind when i saw the pic- that it wouldn’t stay put for too long. that big ass head is just bound to rub all over the inside of the receiver
I cannot find that item. Would you provide a link?
I have broken and bent a lof standard pins and have not been able to do so with these.
On purpose with your hands or through wear and tear in a rifle?
brownells.com Item # 989-015-014…but it shows as out of stock.
231-000-073 is a single FPRP showing in stock for $1.43.
#430-000-452 also a single FPRP for $1.13 showing in stock.
These are worth every penny. I have not broken a standard FP retaining Pin personally, but I have replaced enough broken ones in other people’s bolt carriers to know that the KNS is cheap, nigh-unbreakable insurance against a tied-up bolt carrier. I have them in all my carbines.
Also, you will never struggle to bend (without tools) the two ends of a standard pin back into shape just that last tiny bit, enough to slide back in again easily. That alone, for me, was worth $9 or so.
what is the price of these ?what would two dozen cost me ?
ONG,
I believe they are right around the $8 mark.
I replace the standard pin when I rebuild the bolt at 3k and again when I replace the bolt itself on a fighting gun at 5k.
Thank you. Am I alone in finding brownells.com difficult to navigate?
Nope. The search function isn’t the most user friendly. I usually end up thumbing through the catalog to find what I need and enter item numbers in the search box to add items to my cart.
Grant, I checked the link and it’s not there…
not to start a shit-storm from fan-boys,but, i have two daniel defense uppers---- you EVER pull the retainer on one of them bad-boys—you’d best have a replacement pin to get it back up. the first i wondered what i did wrong— the second i thought i was seeing a pattern here… i figured they got them from some little brown guys in mud huts, replaced them with B//M’s that would go right back in, have since re-ordered some more to have on hand from G&R. the bottom line to me is that if you get a D.D. fifle [or upper], get some spare firing pin retaining pins. mud-hut shit from the factory.
