Sir Stephen Posted July 1, 2014 Report Share Posted July 1, 2014 used mine this weekend, loved it. still need to get used to counting my shots, and remembering when i have already loaded the next shot, but managed to get some nice kills with it. Has anyone found issues when racking the gun in 6 shot mode? 3 or 4 times during the day i found that it jammed about 3/4's the way though racking, and i needed to remove the shell, before i could sent the action forward again. i have a suspicion it might be a dodgy shell, as it happened twice in the morning on 2 shell, then twice in the afternoon on 1 shell again (no idea if it was the same shell though, will have to mark the shell next time and check) i was also using Gaurder .28's, but i don't believe these where a factor.

Bleedout Posted July 1, 2014 Report Share Posted July 1, 2014 I have had the above happen once or twice but put it down to me not pulling the action far enough back before trying to pump it forward. could be a weak spring in a shell not feeding quite as it should / with enough pressure and the heavy bb's just making it worse. 1 Quote Link to post Share on other sites
Spam Posted July 1, 2014 Report Share Posted July 1, 2014 If it's only happening on 6-shot mode, then it is loading nozzle not feeding the the 6th bb in the top barrel properly. Popping the shell out and racking it/firing a couple of times will clear the jam, if you try and force it with the shell still in there's a chance the top of the loading nozzle could break.

mimesis Posted July 3, 2014 Report Share Posted July 3, 2014 New part. Steel loading plate. Quote Link to post Share on other sites
Trap Posted July 3, 2014 Report Share Posted July 3, 2014 Didn't realise SAT did cheap tight bores for it as well. Never had anything from SAT. Anyone know what their quality is like? The quality of that loading plate doesn't exactly look great even from just a photo. Quote Link to post Share on other sites
onizuka-gto Posted July 4, 2014 Report Share Posted July 4, 2014 New part. Steel loading plate. sorry if this sounds like a silly question, but where exactly is this suppose to go on the m870? Quote Link to post Share on other sites
GSO-Geko Posted July 4, 2014 Report Share Posted July 4, 2014 (edited) New part. Steel loading plate. On the inside, just in front of where the shell goes. Not sure that this is such a good idea. I've tried different weight bbs in mine, all the way up to .43g, and above .28 it seems like the spring associated with this part isn't strong enough to move all that extra mass. This could be a good investment if it came with its own, stronger spring. But this is one of the least in-danger-of-breaking parts in the whole system.

onizuka-gto Posted July 4, 2014 Report Share Posted July 4, 2014 ah, i get it. i never taken the internal casing within the metal receiver apart, so that explains why i've seen it before. Also why would you use any bb above .23? It's range is already short enough..... Quote Link to post Share on other sites

Also why would you use any bb above .23? It's range is already short enough..... Bumped up the FPS with HPA and a hammer spring mod. Polished the barrels, glued the brackets on the end of the barrels in place so it can't move. Now I'm getting man-sized spread out to 150 Feet (approx 30 meters), and can engage out to 200 feet (approx 65 meters) with 0.25s. Point is, for a given diameter, an object with more mass will end up having a longer range due to momentum. Also, tighter spread. Quote Link to post Share on other sites

Oh! you hooked it up to an external gas tank, no wonder you are using such heavy BB's. I'm surprised they let you have such a setup! How do you control the power? doesn't it have to be under 400fps?

Atsalakotos Posted July 4, 2014 Report Share Posted July 4, 2014 But this is one of the least in-danger-of-breaking parts in the whole system. The stock pin on that part is plastic... Mine broke within 30 shots (Probably a lemon) so at the time I had to get it machined. I think thats a very good choice for people who dont have access to machinery...

How do you control the power? doesn't it have to be under 400fps? I use the regulator on the tank to keep it just under 100 PSI. The stock pin on that part is plastic... Mine broke within 30 shots (Probably a lemon) so at the time I had to get it machined. I think thats a very good choice for people who dont have access to machinery... Definitely a lemon. My point is that it might be too heavy for the gun to function properly. I would like to see more replacement parts for this replica. Quote Link to post Share on other sites
bigguyairsoft Posted July 4, 2014 Report Share Posted July 4, 2014 GSO-Geko can we see a picture of your setup thanks 1 Quote Link to post Share on other sites

Also why would you use any bb above .23? It's range is already short enough..... It seems to easily overhop .25s already - I think it could take .3g BBs quite easily and the range would surprise many! Quote Link to post Share on other sites

Bleedout Posted July 5, 2014 Report Share Posted July 5, 2014 Anyone in the uk recieved the angrygun stocks yet?. Was looking at them compared to the G&P offering but wondering how people are finding them. Quote Link to post Share on other sites
mimesis Posted July 5, 2014 Report Share Posted July 5, 2014 Now there's a second one of these, so I am forced to conclude that there is a demand for them coming from somewhere. http://shop.ehobbyasia.com/pro-arms-cnc-aluminum-loading-arms-for-marui-m870-gas-shotgun.html#.U7iBUXlOWAg Quote Link to post Share on other sites
Habakure Posted July 5, 2014 Report Share Posted July 5, 2014 Or it's a part that people want to change, not because of failure, but customising? Quote Link to post Share on other sites
Stuey Posted July 6, 2014 Report Share Posted July 6, 2014 Customising the invisible internals of the gun? Probably not. Quote Link to post Share on other sites
BerserkDS Posted July 6, 2014 Report Share Posted July 6, 2014 I've seen one fail on a brand new 870. Quote Link to post Share on other sites
Habakure Posted July 6, 2014 Report Share Posted July 6, 2014 (edited) You mean, it was opened up and then you saw the failure? I haven't heard of this part failing to be honest, but that doesn't mean it hasn't failed out of the blocks (brand new, try to fire it and poof it brakes). Regarding the 'replacing just for replacing sake'. Some people do that, esspecially if it's replacing a part that's more expensive than the original.

Norotor Posted July 6, 2014 Report Share Posted July 6, 2014 Mine failed after a couple weeks; would not load BBs for 2-3 pumps, when it would it would only load 1 or 2, in 6 shot mode. Opened up the m870 and the arm wasn't functioning properly. I don't think it's the arm itself though, but the pins that hold it. Quote Link to post Share on other sites
Habakure Posted July 6, 2014 Report Share Posted July 6, 2014 Was it a first batch or bought within the last 5/6 months? Just curious you see (something to keep an eye on). Quote Link to post Share on other sites
