B.T.A.S. Regulator System:
* Both models are fitted
with our highly regarded regulator system, incorporating revised hammer
weight (30% less cocking effort), revised stroke and ultra low friction
movement.
* The standard Air Arms valving is discarded or modified resulting in
more than double the standard rifles shot count with no power curve
and closer to the legal limit.
* Typically we achieve 120 shots from a .177 cal AR400/410K and 140
shots from the classic length in .177.
* The .22 cal gives 140 shots as a K and 160 as a classic length.
