Had a PSA Gen4 9mm firing pin fail and although eventually they sent me a replacement,"thank you" they didn't have them in stock to buy at the time so I bought this one in the mean time. It fit right in spring and all. Tested it and had no failures after 200 rounds. This seems to be the Colt style firing pin for 9mm AR. Always verify the type of firing pin you have and measure it before installing it using a caliper or armorer. Thank again Optics.
Pros:
Relatively affordable
Cons:
None
Best Used for:
fit in my PSA GEN4 9mm BCG
Would recommend: Yes

I broke my firing pin and spring on my PSA ar 9 and this was a solid replacement and the price was right on. Other company’s wanted a lot more $ for theirs. Optics planet has always had my back with any gun parts and supplies I needed. Quick shipping and they always have some kind of coupon code and free shipping for orders over $50.
Would recommend: Yes

All I really needed out of this was the spring. The one I got stock from BCA was so weak that after a year or so, it started causing slam fires. I'd pull the trigger and in less than a second, my entire 20+ round mag was gone. Terrifying. I reached out to BCA but didn't get any help so I tried this and it fixed it.
Pros:
Fixed my issue with a BCA weak spring
Cons:
None
Would recommend: Yes

The description makes it sound like it will fit all PCC BCG's However These will not work on Glock style Bolt carrier groups/ Magazine wells or lowers that use Glock style extractors like Aero Precision. These are for COLT style BCG's and extractors The spring is bigger/thicker/longer so it will not fit into any of my 4 PCC bolt carrier groups! But.. the actual firing pin will work seems to be sturdy well made I was really hoping the stronger spring would have fit but NO!
Pros:
nice firing pin
Cons:
spring only works with olt style BCG's
Would recommend: No

Got a colt style 9mm bolt carrier group needs a new extractor? This is hard to find and if you find it it is Expensive! I have on in my ar45 that I made.
It will work on 9mm, 45acp, 10mm, 40sw as long as it is colt style ramped pcc bolt carrier group. I have broke the first generation one. This is actually Gen2 with a tension bend that gen 1 did not. Made of better Steel than gen 1. I did NOT break Gen 2 yet so it is still in my defense ar45. I would know about this extractor as I went to R&d precision with my wife at Lake Havasu for vacation and gotten a few to try.
It fits well and comes with the extractor roll pin. You need to buy this kit and stow it away.
Pros:
Gen2! better than Gen 1, Affordable
Cons:
for Colt style pcc bolt carreir groups
Best Used for:
PCC PDW rebuild
Would recommend: Yes
