Smk b2 air rifles

[Talon]

Well i have to admit i never got into the Theoben gas ram craze that was quite predominant when i was highly into air rifles (i enjoyed tinkering with mine which the gas ram doesn't really allow).As far as im aware there was never a tuning kit made for the B2.I used to machine my own part's for my air rifles (very easy with access to a lathe).My particular B2 though nothing special had decent rifling and a secure lockup (think poor mans HW35) The trigger was atrocious compared to the Rekord or the air arms CD,it had a lot of creep and a let off of 5lb's (tested with kitchen weights).it still hit the target though.
My absolute favourite was the webley mklll i've owned four of them.Very outclassed compared to modern air rifles due to the low swept volume and the tap loading port was very inefficient but perfectly adequate if kept under 30 yards.A B2 is very cheep and cheerfull, but it will do the job and yes it will take a bunny with correct shot placement

Forgot to add Robb,you could try fitting penny washers in the piston,a brass hat washer is preferable as it will help seat the spring as it acts as a secondary spring guide and also aids in the spring unwinding when the gun is fired, but washers will help as they add weight,i would ream the transfer port out,3mm is the absolute maximum from what i remember so i would go smaller first and chrony the gun to check the results.Also polish the exterior of the piston,i was taught to polish it in straight parralel lines but clamping the piston in a drill and using various grits of wet and dry always worked well for me.It's been a few years since i modified a spring gun but i spent many a happy hour tinkering with my air rifles
