Hammer spring weight for AR15 pistol caliber carbine???

[KennVFRidr]

I have a Fulton Armory AR built lower using their "National Match Service Rifle 2-stage, non-adjustable" trigger assy...hands down best trigger I've come across. When I got my Oly Arms K10 upper I used the Fulton Armory lower with it a bit, but really disliked the huge polymer 18 round magazines that came with it. I snagged an Angstadt Arms 1045 receiver set and assembled the lower with a standard parts kit but used a reduced weight hammer spring on advice from RMWXtreme. I have not run a lot of rounds through it, but no issues either way as yet.

Just wondering if anyone has had any primer problems with standard hammer spring weight when using a pistol caliber upper???

A proper PCC hammer is the way to go.

Thanks for the link, I'll look into it...but new upper will be direct impingement not blowback.
