Got inside this gun,several times
not really troublesome inside though its best to diagram it out.
Took apart the expansion chamber gave it a lube, still have issues with gas leak but it seals itself after a bit of a filling.
Took the opportunity to purchase a Pro Arms valve kit, will discuss when I install.
Found WIITECH on the bay,
purchased and installed the set of aluminum loading arms(both not just the single one that PA and some other have in steel) they are working as they should.I did put a thin film of superlube between the plates.
WIITECH also has a bunch of other M870 upgrade parts,
a stainless steel valve pin(which I think may be my culprit but didn't install due to ordering Pro Arms valve kit after)
2 aluminum nozzle sets for duster or TOP(propane)
an aluminum hop housing
a 3 barrel upgrade
Steel lever set
steel hammer
steel trigger upgrade
and other upgrade bits
shipping has been auto refunded as I purchased in bulk several times so first package with loading arms and steel valve was about $13 USD but original shipping at checkout was about that per item
it came Airmail with signature,took appx 5 days to get here and a bunch of dead time with Canadapost and CBSA
Have not seen this brand at any Airsoft sites I visit and they have a lot of upgrades for many other items so I'm surprised at just finding them
I will update with my findings as I receive and install
I have the Angry Gun gas stock installed and now that my M870 works well enough I am pleased with how it works, I still get the tank running empty after a bit in storage but am so far blaming it on the expansion chamber
Had sold my Tonic gas tank and had received notice that it seemed to swell much like the stock marui one, and buyer could not get it to fit in the stock. I had managed to get a few shots out with it and had no fitting issues, though I only filled the tank 2wice before my oring troubles and that from a not so full propane tank,
Happily got a fun shotgun now, sadly brand new ones are now available for less.
Happilly it looks very easy to tap the stock fitting with a 1/8 threading so it's HPA friendly, I wish I knew how to though.any capable takers here?
Anyone got a line on Breachers for less than$600 taxed in Canada?
and finally, has there been consensus yet as to how to chrony this gun at games?
