  • I CAST THEREFORE I SHOOT
Anyone ever have a problem breaking Hammer pins right in the center groove?

This lower is just a Spikes lower I bought from Dan 4 years ago (just before Obamas re election)
originally on a piston carbine upper. (3 pins)

2 months ago it went on my on my 18 inch DI rifle length system (2 pins),

Standard buffer and spring, ammo is 55 gr clippin around the hi 2900 to 3000 fps mark.

Standard mil spec pins is what Im told I purchased.

Any Ideas


Nice marmot, man.

Check your pin location guessing your lower is out of spec

If the lower is out of spec KNS or JP pins will most likely solve your issues, if you’re using a standard mill spec trigger group I would replace the hammer at the same time I replaced the pins.

Maybe its time for one of those modular drop in 3 gun trigger groups.

On the other hand I would like to find out if it is out of spec.
Where or who should I take the lower to to find out?
