8 months waiting on the stamp, finally glad to have this assembled:
Firearm Gun Trigger Gun accessory Airsoft

BUT - whereas the stock is extremely snug fitting, the top pin hole is canted to where I can't seat the push pin.


what is the recommended fix here? There is absolutely no play in the B&T stock and there doesn't seem to be a reasonable amount of hammering this with a mallet that will seat this.
Presume it'll run a few rounds, but need a good long-term solution.

appreciate any leads!

Some of my pins were like that and needed a little convincing to go it. You need that pin to seat fully, don't shoot it like that.

Just some ideas to try, put the gun muzzle down on a hard surface and push down hard on the stock while seating the pin, flip the pin around and try it from the other side, try a different pin, try a little oil on the pin, try tapping it in with a nylon hammer/punch, try playing with the insertion order of those two pins. I would try all those and futz with it for a while before doing anything more dramatic. Chance are you will get it.

Congrats on getting the stamp, out of all the SBRs I have done, I like my MKEs the best.

Mine was the exact same way with that B&T folder. What I eventually did was put the stock on and made sure it was fully seated then got a drill bit close to the size of the pin (slightly smaller) and ran it trough a couple of times making sure not to take away any material from the gun itself, only the stock. Works great now and the stock is tight with no movement. It just took a tiny bit to get it to fit so don't be scared to try it. Sounds worse then it is.

thanks for the input! Took the stock out and opened up the top pin towards the top/front and after a few cycles of trim/test was finally able to get the pin to seat. It's still super tough and will be a bear to get out, but certainly isn't going anywhere.

FWIW my B&T folder on an MP5 clone was VERY tight when new. With a little oil and force I eventually got it on without modifications. With time it has "worn in" fits great.

This is what you want to do.

Make alterations to the pin hole in the STOCK, not the gun, and not while it's on the gun.

I ran drill bits through it carefully, in increasing sizes until I achieved a tight, but workable fit.

B&T needs to work on their QC tolerances. At their price point a misaligned pushpin hole is unacceptable. Had the same issue with mine on my SP89.

I think they just make them VERY snug from the factory to prevent any OVERSIZED holes. It's a lot easier to fix an undersized hole than it is to fix an oversized hole.
