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.
On purpose with your hands or through wear and tear in a rifle?Quote:

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.
ONG,
I believe they are right around the $8 mark.
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.
I replaced all the standard firing pin retaining pins in my rifles with the KNS perma pins after experiencing a major malfunction due to a broken cotter type retaining pin. The pin broke and the small broken end worked its way out and bound my bolt carrier in the upper receiver of my LWRC M6A2.
