SP1 Configured 9mm Bolts

.223 and 7.62 Carriers can be converted.

Colt Style 9mm bolts ramped and modified for use with RLL's.  I can replace the existing weight in the bolt with Tungsten (over twice as heavy as steel)  The added weight will help counteract the weight removed and the ramping of the bolt. The weight removed does contribute to the rate of fire increase but the ramping is the main contributor. Ramping allows the hammer to be re cocked so easily the rate of fire increases.  Use Tungsten and a Rate Reducing Buffer to slow down the rate of fire and help protect the link from the abuse of the 9mm blow back design.
