Bowkett FWB piston

[Garvin]

Thanks for that Garv, it also looks like a piston liner has also been added. I have both a 124 and 127, and the 127 in particular, with a Maccari kit, is a joy to shoot

Can you tell me what the transfer port is opened up to on yours, and also what the barrel length is? I have read the article in the link below, but was a bit reluctant to try any mods as I'm afraid to modify mine in anyway unless it's a genuine improvement on what are great little rifles.

OK Pete, here's a rough idea of the FWB Bowkett transfer port diameters, subject to it being impossible to measure accurately while holding the cocked barrel plus a torch and sticking digital calipers between the breech jaws.....

The port on my 124 Bowkett is about 4mm, the 127 Bowkett is about 4.35mm and a factory standard 127 is around 3mm.

I couldn't see properly what, if anything, JB did to the inside edges of the port in the cylinder when I had the 127 apart.

The barrels on both Bowketts have been shortened to about 13 inches including the breech block.
