.223 piston & polymer
added adams arms, piston, 1 in 7, melonite, upper to new frontier polymer lower.
its a experiment, did due diligence as to why frontier arms and adams arms.
want to see what it's all about with pistons?
will see if things start crumbling/cracking/melting.
yesterday, 60 down range- no problems at all.
trigger very heavy, maybe ~10 pounds.
~ 2.5moa with factory.
new frontier armory will send me a lighter trigger spring.
already mollied trigger surfaces to see how that works.
