aznriptide859 Posted September 12, 2013 Report Share Posted September 12, 2013 I recall seeing a link to your project progress umisodachi, do you have pictures/details for the gas tube conversion? Thanks! 1 Quote Link to post Share on other sites
chas Posted September 12, 2013 Report Share Posted September 12, 2013 Here you go. This guy is awesome. http://unisodachi.militaryblog.jp/e469317.html The bmod actually seems kinda simple with the right tools and skills. No challenge for an airsoft company, so either Marui makes this as a kit, or someone will clone the G&P kits and adapt them for the TM. Really hope Marui does it: I think it would cost 400$ as a full gun. Quote Link to post Share on other sites
umisodachi Posted September 12, 2013 Report Share Posted September 12, 2013 I am sorry that you and a reply are overdue. It is the gas tank of "GP391 M870 6 Position Extended Buttstock" made from G&P which is being used by this reconstruction. The connection method of the gas tank my Tokyo Marui M870 processes a screw inside the gas route by the side of a main part, adds the end connection of a gas tube, and connects it with a gas tank. However, since the main part only shaved off screw processing inside a gas route, and a part of trigger guard, it can also be returned to M870 of an original state. Those processings are performed and the gas tank is installed for the inside of a pistol grip into through and the stock tube for GBB. Quote Link to post Share on other sites
aznriptide859 Posted September 12, 2013 Report Share Posted September 12, 2013 That's pretty damn smart, I didn't know the extended stock came with the gas tube. How many shots can you get from a full gas charge? And did the kit include the proper tubing to reroute the gas? Quote Link to post Share on other sites
bigguyairsoft Posted September 12, 2013 Report Share Posted September 12, 2013 umisodachi did you use a G&P ris forend for the pump? similar to thishttp://shop.ehobbyasia.com/g-p-m870-ris-forearm-set-short.html Quote Link to post Share on other sites
umisodachi Posted September 12, 2013 Report Share Posted September 12, 2013 (edited) Although I am using HFC134a chlorofluocarbon here, once it fills up gas completely, discharge is possible about 25 times.However, since it becomes easy to flow through a liquefied gas into the vaporizing chamber inside a main part in case of this system, unevaporated gas is emitted several times from the first discharge. However, since white smoke comes out more violently than a muzzle of a gun, I who have shot am pleasant. Although it is the parts used for the gas route used for these reconstruction, in the portion attached to G&P products, only a gas tank and the parts for a part of tank fixation are used. At attached gas hose and end connection of G&P products, since it was vulnerable, a gas hose and end connection newly because of connection needed to be exchanged. In addition, although the additional pipe for keeping a gas tank from entering is put into the rear, in accordance with required length, it is starting by itself. In addition, RIS which I am using for a pump removed the regular pump, and has only stopped RIS for M4GBB with the screw. When it was G&P M870 RIS Forearm Set, since the path of the magazine tube by the side of G&P products was thin, use to Mary was not completed.

aznriptide859 Posted September 12, 2013 Report Share Posted September 12, 2013 Hmm, only 25 shots? That seems a bit low, compared to the advertised ~100 shots per TM cartridge. Quote Link to post Share on other sites
umisodachi Posted September 12, 2013 Report Share Posted September 12, 2013 Though regrettable, since the gas tank made from G&P is used, by this reconstruction, it will become half rather than the capacity of the gas tank of an original Marui regular article. It considers converting the stock tube itself into a gas tank from now on.Expectation is carrying out reservation of capacity equivalent to Marui by Colet. However, the manufacture here is likely to require time. Quote Link to post Share on other sites
bigguyairsoft Posted September 12, 2013 Report Share Posted September 12, 2013 so the G&P ris pump will fit yes or no? do you have pictures of how you made the pump using the mauri one? Quote Link to post Share on other sites
umisodachi Posted September 13, 2013 Report Share Posted September 13, 2013 Although I am sorry, it is forgotten to take the photograph in the middle of manufacture of a pump. About the pump for shotguns made from G&P currently sold at present, attachment is difficult, and processing is required. However, since G&P is due to manufacture the part for Tokyo Marui M870 by a future schedule, it may be good to wait for sale from now on. http://www.gp-web.com/en/productspop.php?pid=3338 Quote Link to post Share on other sites

TheFull9 Posted September 13, 2013 Report Share Posted September 13, 2013 Well.. at least someone's making stuff. Not surprising it's G&P. Having rails on top and on the pump makes sense, you can actually use those. All that chunky stuff just behind/around the muzzle seems really pointless to me. Quote Link to post Share on other sites
hitmanNo2 Posted September 13, 2013 Report Share Posted September 13, 2013 (edited) Jesus. That G&P thing looks mean as *fruitcage*. Like it lives on diet of small babies. Having rails on top and on the pump makes sense, you can actually use those. All that chunky stuff just behind/around the muzzle seems really pointless to me. No different to fully railed ARs surely? Mount lights and PEQs e.t.c. up at the front. Edited September 13, 2013 by hitmanNo2 2 Quote Link to post Share on other sites
TheFull9 Posted September 13, 2013 Report Share Posted September 13, 2013 (edited) Quite different I'd say. You're always going to have your support hand on the pump, ready to cycle the action after each shot right? Putting something like a light all the way up there just wouldn't make much sense (to my mind anyway) when you could just get the railed pump instead and put the accessory in question right next to the hand you're going to use to activate it. I suppose you might potentially same some light/laser splash on the mag tube or the end of the barrel, but it's going to comparably be very slow and inefficient to manipulate compared to simply mounting stuff where you can hit the buttons without having to move your hand. I certainly wouldn't be putting things way out there personally. If people wanna rock it then hey, crack on, it's airsoft. I'm sure lots of folks will just like the fact it looks different, which is entirely their choice. But when most people have a rail on an AR (or indeed any rifle) they tend to put their electronics in such positions whereby they can press the switches with a simple movement of a thumb, not having to reach somewhere with the whole arm, hence why I would say it's different.

hitmanNo2 Posted September 13, 2013 Report Share Posted September 13, 2013 Yeah. I was figuring using remote switches but you would have to have quite a bit of slack to take into account of the pump. It would have to be cleverly managed I suppose. Quote Link to post Share on other sites
TheFull9 Posted September 13, 2013 Report Share Posted September 13, 2013 I mean yeah, if you're using one of those extra long coiled-wire remote switches that look like the cable from the handset on a standard old house phone i.e. the type which always seem to come with clone lights/lasers, then that'd work. But I don't see many people actually using those in game to be honest and I don't think a lot of players would like the aesthetic. Quote Link to post Share on other sites
spawn_lee Posted September 18, 2013 Report Share Posted September 18, 2013 Can someone tell me if that Mesa Tactical model "High Tube" stock adapter replica (picture posted above) is or is not compatible with RS 870s? http://mesatactical.com/products/high-tube-telescoping-stock-adapter-and-rail-kit-for-rem-870-12-ga-9-in-rail/ Quote Link to post Share on other sites

onizuka-gto Posted September 21, 2013 Report Share Posted September 21, 2013 anyone know how to convert the new TM M870 GAS shotgun to a pistol grip?The default one, is driving nuts. Hell, i got a M1100, maybe there is a way to break that up and put it on the M870..... hmmm.... Quote Link to post Share on other sites
Horsem4n Posted September 22, 2013 Report Share Posted September 22, 2013 just wait for TM to release the pistol grip kit. they said they would. Quote Link to post Share on other sites

You better not be lying, you'll make a grown man cry if you did.... *takes his pristine M1100 shotgun off the sacrificial alter* Quote Link to post Share on other sites
notrabies Posted September 23, 2013 Report Share Posted September 23, 2013 (edited) If you're nuts you could always get the G&P buffer tube adapter for the Maruzen M870/M1100 and find a way to rig that on, as that also includes a little tank inside the buffer tube. This guy right here: http://www.dentrinityshop.com/pr_details.jsp?pid=9377 Should work, but I'd certainly expect some modifications required on the fitment and gas line side of things.
