The new Shift kit uses a unique insert system that cannot be swabbed out and behaves exactly the same as a 2 piece barrel. The kit includes a 14" barrel, 4 inserts (0.685, 0.689, 0.693, 0.696), MacDev swab and plastic spanner in a tough carry case.
The new Shift kit is the lightest alloy barrel available today. it also uses an expansion of the highly successful MacDev porting for quiet operation.
The kit includes an autcocker threaded back, 14" tip, and 4 bores (0.685, 0.689, 0.693, 0.696).
