Tench Regulator & Tune (Includes a full service)
The Tench Regulator & Tune packages are designed to make your rifle more consistent and air efficient, not more powerful. All sub 12 (non FAC) rifles are set to around 11.5ft/lbs after any work is done, keeping you well within the legal limit.
As Well as fitting a Tench regulator and tuning the rifle we also engrave the breech block with the words RAT WORKS as a way of showing that your rifle has been regulated and tuned by us, this is free of charge. If you would like extra engraving as well please select from the drop down menu above and you will be charged accordingly.
