I try to find a place where I can get a M4 pistol grip and a crane stock to fit on the AG gas chamber. Anyone have an idea? Airsoftparts and airsoftstore don't have both of them. Thanks for your help!

does anyone know where we can get replacement parts for the TM breacher?

What parts you're looking for??

Just find some buddies with WE M4s that have swapped grips and stocks.

I'm looking for a tm breacher pistol grip.

looking for info on the 2 orings for the inlet valve in the stock, that the gas resevoir valve pushes into

can't find it on the parts diagram

sadly 1 of mine had shredded and the gas dumps with only 1 in
can anyone help me save $200 on an AG m4 resevoir purchase by
helping me with a $2 oring
also looking for a replacement butt pad unit

I only have 870T-56, the one you need looks a bit thinner, not sure if they are the same.

If you do still have it in hand (oring), bring it to a local hardware store but with clerk behind a counter. I destroyed my AG oring and he found me some. Picked up 3 for 2.75$. If you can remove your part, bring it with you to test it.

Any idea of the 870's compatibility with real steel as far as the pump/handguard goes? I hate how skinny the stock one is D: How much modification would it take to put a RS, or perhaps a maruzen pump on?

Went with the Angry gun stock adaptor..it was great.. for a day..
I seem to now have developed a major leak from the front of the gun.

I have removed the stock, and lubed the o ring to the resevoir and oring around the mounting screw
but I still get all the gas just escaping out the loading area as if there is a seal missing, as it blows out just as fast as I fill..or something is stuck in an open position

the day before I had taken a few test shots when I first installed the AG stock and had great fun shooting but found the gas empty the next day, figured it just needed some rings lubed but now its gone all to shit

Do you think the gas leak is coming from between stock and receiver? Check above post, "fixing gas leak between stock and receiver". That possible after you changed the stock and leave some space on between. Get extra one more o-ring from dollar store, hope that is it, good luck.

Sadly no,
its definitely near the loading area around the brass tube and spring..somewhere inside around there

the brass tube and the spring? I try to find it and cant see it. I did test mine and it kept the propane in for 1 week in the tube without leaking (it sit about 1 meter from my bed, I would smell it). I can only see it's an oring snapped or the valve is not tight enough/oring snapped.

One of the reason I would like to keep both of my Marui M870 and breacher with original external gas tank, is that when I'm done gaming, I just remove the gas tank, without keeping the gas pressure in internal parts, it might reduce the life of use. Keep it healthier. Marui design for 134c mainly. Green gas and propane have excessive pressure to shorten life of use. Also can carry more extra tank for gaming. I have five tanks for breaher.
I suggest empty your AG gas tank after game use.

Where you load the shell you can see the brass tube and spring mech straight ahead..the gas seems to be venting about 1 cm to the right

I'm sadly going to break it down

Thanks for the help
