I would like to have a parts surplus on hand. Is a titanium pin worth the 40 bucks or just get the steel pin. Thanks

Unless your shooting a precision AR15, long range rifle using custom reloaded "accurate" ammunition, there's is no need whatsoever to utilize the titanium firing pin.

Most comments will tell ya they have all kinds of problems, (which is not true in my experience), pierced primers, etc....

I use one in my precision AR, mainly to reduce the possibilty of slam-fires and because I use Remington 7.5 BR primers, which aren't as "hard" as other choices. I have fired thousands of my red-line custom 77 grn. SMK reloads thru it and NEVER had one problem. YMMV

added: btw this is a great kit for "extra" parts: www.bushmaster.com/shopping/lowers/arpartskit.asp

And also the standard firing pin is not "steel" (which would be too heavy and cause slam- fires) but some sort of aluminum alloy.....

Thats what I thought. Thanks for the link Mike... KM
