In one web forum, it was mentioned about the AR15 model’s trigger sometimes not firing with the military “hardened” primers & the recommendation to use an AR-10 trigger instead. My question is how this is going to affect the firing pin over the long run. Obviously if the FP of a 15 is designed for a certain amount of force, and one increases that force (stronger spring in the 10 trigger), it is essentially going to either shorten the life of the FP or cause a failure (thus shortening it’s life).
I’ve got quite a bit of mil-surp ammo & would hate to have multiple FTF’s simply because the primers are hardened, but on the other hand, it would not be an ideal situation to have the FP crap out, either. Perhaps a titanium FP could alleviate a lot of this concern? J |

AR-10's have different triggers? When did that happen?
I thought they were the same... My understanding was the firing pin is the different part; the AR10 has the spring loaded pin vs the free loating 15 pin. Experts chime in please, I'm getting ready to help a friend assemble a 10 soon and this would be useful info to have..... |

However, in Timney's case, the AR10 hammer has a tail and is only available with a #4 pull weight. Whereas the AR version comes in either #3 or #4 and doesn't have a tailed hammer. |
