Browning / Miroku BL22 Tuning Kit
Shotgun Boogie's tuning kit browning BL 22 / Miroku 22lr.
Sometimes the sear spring is to weak. For that case I added a second sear spring to the kit.
This kit requires fitting by a competent Gunsmith.
From a customer:
I thought you might be interested in the results of installing the Browning BL-22 Tuning Kit:
Factory original springs: Trigger Pull: 100.45oz., SD 6.796, ES: 25.5.
BL-22 Tuning Kit springs: Trigger Pull: 67.4oz., SD 2.484, ES: 8.2.
The above is an average of 10 trigger pulls.
That's a reduction of: 32.81oz. of trigger pull (32.66%), SD: 4.312 (63.44%), ES 17.3 (67.84%)
Amazing difference and a massive improvement in consistency! My BL-22 is now a pleasure to shoot.
