liquid propane is getting into the gun, thats my whole issue. jhalek, thats almost identical to the setup im using, i just dont have the valve. the reason liquid propane is getting into the gun is because i have the tanks upside down, because when upright they only get about 60 psi, and that barely ...

Alright guys I have another question for you. I started running my bbmg on 1pound propane tanks a while back, but the problem is that the propane expands when it hits my guns chamber, causing everything to ice up, and jam. I bought a co2 expansion chamber online, but it does not seem to help. i have...

put a hop-up bucking over the barrel and put rubber bands around it so they detent into the barrel, but dont make it to far down. this will raise your rof and fps because higher pressure builds up in the gun.

yeah, cutting a slit and then using an actuall hop-up bucking works really well, turns out if a just straight up zip-tie the rubber into the slot it needs crazy pressure to shoot, the rate of fire was insane like that though lol, no doubt passed 100 rps. but it wasted a lot of gas, and the chamber a...

i actually lost the o-ring i was going to use but found a spare hup up bucking... so i cut slits with a hacksaw, and then filed them to make all the slits even, i made it slightly smaller than a normal airsoft barrel hopup cut, and it works phenomenally. I then just put a small ziptie around the buc...

alright, ill attempt it later today, i just have to make sure that the slit is perfectly straight up and not tot he sides...

Alright guys, i know there are a few topics about this on here already but i couldnt find them with the search. So i was thinking about adding a detent into my barrel, and was wondering if my simple idea would work. I plan on using a hack saw and cutting out a slit from the top of my barrel, right a...

I tried a few online cnc companies and they wanted over 200 dollar for an aluminum block with a hole in it lol

Where did you get that pretty block from? I'm definitely interested in one.

the rig is actually on a remote line setup, just tip the can upside down and throw it in my pack, the line itself acts as an expansion chamber, and then goes into the handle. it delivers about 150 psi and all of it is not completely expanded out of liquid form. (I have a Gauge before my blowgun) I h...

well looks like im takin this to a local game tomorrow haha. hopefully my propane rig and new air handle work correctly!

JB weld seems to be the answer for everything around here haha. Ive never used the real stuff just the crappy 1 hour cure, that stuff doesnt hold for crap.

yeah i did just ram the head into the hole lol... but i found a nipple that worked and its solid and leak proof now.. a 1/4" NPT nipple fit both the hole i had drilled and the threads on the end of the blowgun, thanks alot JDP. I just hope the aluminum doesnt give out, and strip.. I dont know what i...

I already have a hole drilled i the chamber though, and the nozzle itself goes through it, so i doubt i would be able to tap a 1/8 npt thread into it lol

Alright so i have my BBMG just about finished, it only needs a few more little tweaks, but i keep sprining leaks around my blow gun, its just on of those cheapy ony you use on air compressors. I see alot of people with the same concept as me, the handle just sticks out of the tube, but theres never ...
