Many people have asked me to do this and I’ve been hesitant to since I am finding so many variances on different Titanium FP’s I’ve tried. Fortunately there are several sources of Titanium firing pins out there. I used some cheap ones from ‘Total War Tactical’ but they haven’t been in stock for a long time. The first one I ran for probably 50K rounds. The second one lasted maybe only 10K. I got some from HK Parts and those were hit or miss. Some wouldn’t even fit in a Colt 556 bolt and I had to modify them to even go in a bolt. I obviously wouldn’t recommend those. I know some of you are running ones from Iron City Rifle Works. I’ve tried emailing them and left them several voicemails and they never communicated back so I gave up. I got some of these from Anarchy Outdoors. Notice that they advertise these to work in 7.62×39 builds which typically require a longer FP protrusion for deep seated primers typically seen in various brands of 7.62×39 ammo. All that said, these bushings MUST be made to be paired with FP’s that are confirmed to have the appropriate protrusion which is in the range of .028″ to .036″. DO NOT use the provided bushing with any other FP unless you or a a qualified gunsmith has validated that it lands in the range mentioned.
I use full power hammer springs in my builds. I have seen the bushings get deformed after a lot of rounds and it is your responsibility to confirm the FP protrusion over time. I personally have not seen the protrusion go out of range but that is me. I cannot control all the variables of YOUR build or what conditions or ammo you use.
Again, this is MY UNofficial reliability kit.
By purchasing this, you:
- Acknowledge that you may be voiding any CMMG warranty using these components.
- You also assume all risks, known or unknown using these parts.
- You release C3Junkie LLC from any and all liability using these parts.
- There are no warranty’s from C3Junkie on these parts. Again, this is what I personally use and will last longer than the factory alternatives but nothing lasts forever.
- You need to be aware that the protrusion may change over time and you or a qualified gunsmith should check it periodically.
If any of this bothers you, CMMG customer service will replace the factory FP, FP spring and cam pins free of charge when they break and you won’t be voiding any warranties. I do this because in my experience the factory parts do not last long enough for heavy use and I don’t care about factory support.
