GPR Lock Improvement

[JStanley]

Just got my WL liners in the mail.  Gonna visit the machine shop one afternoon next week to do the offset install, hopefully eliminating my FIP problem which cost me a couple of deer already this year.

I finally got some time to run over to my friend's machine shop for a little therapeutic session with a Bridgeport mill.    My only complaint is the touch hole diameter in the WL is a bit smaller than my vent pick that I carry in my bag.  All picking was done with a pipe cleaner at the range.  I don't think I'll drill the WL out just to fit my pick - no need to waste vent life, right?

Be blessed.

How do you get the liner out? I had Chambers send mine directly to Mark, so I never got to see it.

You don't take this liner out for cleaning like you do those with screw driver slots or hex head sockets, etc.  When installing, I counter bored it a tad short so the final position was a slight interference (crush) fit, to make the edges less likely to hold water & rust.  Finally, I used a Birchwood Casey gun blue Sharpie to run a little bluing into the seam around the chamfered edge just as an added safety measure. When the touch hole finally wears out, you simply use the proper drill/easy out combo and it will release.  I also used a little anti-seize before final installation. Since this gun has a wedged barrel, pumping the water through the barrel is still pretty easy.  If it were a pinned full stock, you would just clean like you do a non-vent liner equipped rifle; toothpick in the hole trick.

Nice job JStanley. I did not realize that your vent hole was that far off, I really thought it was just marginal (similar to mine which has given me no trouble at all), but seeing these close up pictures of yours, I see where you could certainly have experienced problems. Very happy you got it fixed! Nice Job!

Thanks for the kind words fellas!  I really had a lot of fun in the shop. Something about the smell of a machine shop.

Ok, my concern was flushing the barrel in a bucket. I wasn't sure it would work with the small hole.

Ok, another silly question. How did you screw it in?

the size of the touch hole doesn't matter at all for bucket flush out cleaning.

the chambers white lightning vent liner has a cut off screw in extension - once screwed in, you hack it off and fair in any remaining vent liner metal flush to the barrel.

What Rob said except I used an end mill to gently mill off the wrench extension cuz I was afraid I would booger up the finish with a file. Since it was in the mill and the tools were there...

Ok, I got it. I thought they were two piece with a liner screwing into a sleeve.

yer WL job is just fine and she'll go off lots better now, for sure.

building another GPR for a friend, just got the rifle yesterday and first thing i did was check the touch hole to pan alignment, it's good.  
notice the barrel test fouling debris inside the touch hole, too ....
