My B50 barrel
So far today I managed to turn my gmac barrel down, drill the tp and finish the leed. It fits nice and everything is in the right place so far.
I’m thinking of gluing it instead of set screws
Got my barrel band done, I am still deciding how long the barrel should be, right now its 24” but it doesnt seem unwieldy.
What do you think is 24” too long?
Managed to take a few quick shots today, I think Im on the right track with this barrel.
I was nice and smooth to push a pellet through. No rough or tight spots.
Mine has a LW barrel and an Alteros regulator. Nice machining by the way. I'm a terrible machinist. If you ever have to change the orings you'll be glad you used the set screws.
I am no machinist that’s for sure this turned out mostly because of pure luck.
Right after I got it put together and ready to take out for a few test shots I thought I just top off my air tank and it started to leak I had to replace the O-ring on the fill valve.
I have another bridge that I’m thinking of converting to 25 and I get a marauder barrel for that.
I’ve done a bit of valve work as well as modified the hammer and installed an SSG so at this point I’m not thinking of a regulator
Now look what Im up to, I cant be stopped lol.
this was a practice run before I cut the barrel.
Im going to use the cut off to make a thread protector.
I have another breech not bridge.
So I cut the barrel to 19” an inch longer than stock and its now threaded with a thread protecter made from the cut off. First time I used a knurler.
Tomorrow I blue.
I was in a hurry but Im not going to reblue unless it rusts.
The mismatched stain on the butt was me cutting the LOP from 15-1/2”to 13-1/2” where I like it. I like the silver barrel band but maybe I should try one in brass to match the cocking handle.
Not sure how many air gunners keeping their old BAM’s ...I appreciate that commitment. Did help rebarrel one (not mine)...some issue barrels are good, some didn’t work out.
Threading it in is a good idea..steel breech seems thick enough, would promotes stiffness.
Don’t see any reason they can’t shoot great given a good barrel. Trigger at least good, can get the valve to be uniform, breech attachment to the tube quite secure, really thick (heavy) air tube.
(At it’s most basic….well secured fitted breech, well secured fitted barrel, uniform air release from the valve, good barrel…..why wouldn’t it shoot well?)
This one ended up with a 14” LOP...a little long for me with a winter coat on , just about right for T-shirt weather.

Not my stock work..bought it used about 2010.
My B50 is a tank and has been thoroughly gone over inside and out. I have spare parts on hand and now it will be much more rewarding to shoot. I think its time to refinish the stock.
