EagleSix 4mm Power Spacers (QTY 5) For TM M4/416 NGRS
These power spacers or “pre tensioners”. They pre tension the spring, so rather than cutting a spring, drop one lower and add a pretensioner for a safer and more predictable increase in smaller increments than cutting.
designed for TM ngrs spring guides BUT they fit many others.
