Are they MIM parts or milled?

and what is the weight of the hammer spring?

I bought one and put it in a 7.62x39 AR.

I looked on line for info but couldn't find it.

They are cast, but not MIM.
The total pull weight on the Varmint weight trigger kit is 3.5-4 pounds.

The hammer spring is a standard hammer spring...your trigger pul lweight comes from the semi-captive discnnector spring.

and I apologize.
I was thinking the hammer spring in the kit, but you did say you were using it with a 7,62x39 upper.  Was it one of our x39 uppers (not the LAR-47, th euppers w emake fo rstandard lowers)?  I ask because ewe use  a different spring in the dedicated LAR-47 builds, but the regular hammer spring in lowers used with the upper kits.

Bonr….Are you trying to use yours in a blowback 22 (just looking at the receiver in the photo)?  If so, that may have caused the damage to the hammer "tail".  The bottoms of the carriers are different enough, and the interaction with the hammer is also different enough, that the hammer may be impacting the inside bottom of the lower receiver.  In that case it may also be stressing the hammer pin and egging the pin holes in the receiver.  You'll want ot check both if that is the case.  We used to have that problem when someone would install a NM hammer in a 9mm carbine (factory builds were all single stage), until we started ramping the bottom of the 9mm bolt assemblies, making them NM trigger kit-compatible (but no longer usable with our old 9mm single stage hammers).
