Wingmann Posted September 24, 2013 Report Share Posted September 24, 2013 That flesh-toned plastic makes me cringe... Link to post Share on other sites
RodrigoMF Posted September 24, 2013 Author Report Share Posted September 24, 2013 It´s really hard find the manual ou HD exploded diagrams for this guns... Sorry the bad photos.. Link to post Share on other sites
Deinhardt Posted September 24, 2013 Report Share Posted September 24, 2013 Always interesting to see the insides of these clones, I can see at least one part of that trigger mech that (at least appears to be) the same as a piece of the mechanism found in the Maruzen Gas 870!

3vi1-D4n Posted September 24, 2013 Report Share Posted September 24, 2013 Is it possible to fit the G&P Shorty mags into the A&K? Link to post Share on other sites

renegadecow Posted September 25, 2013 Report Share Posted September 25, 2013 That flesh-toned plastic makes me cringe... That's nylon. Very likely even stronger than the other metal parts. Link to post Share on other sites
Wingmann Posted September 26, 2013 Report Share Posted September 26, 2013 That's nylon. Very likely even stronger than the other metal parts. It's actually the colour that puts me down, not its quality Link to post Share on other sites
swatti Posted October 12, 2013 Report Share Posted October 12, 2013 Notice the loading-nozzle setup has metal-part contacting the cocking-arms unlike MZ that dies on that part very fast. Il post something fun for ya soon... Link to post Share on other sites
Mike_West Posted October 21, 2013 Report Share Posted October 21, 2013 Now, where do I find a 1J spring for CA870 these days? To say nothing of G&P short magazines? Link to post Share on other sites
Aod Posted October 25, 2013 Report Share Posted October 25, 2013 VSR-10 springs are compatible, a stock Marui g-spec/VSR spring should do the trick. Link to post Share on other sites
RodrigoMF Posted October 25, 2013 Author Report Share Posted October 25, 2013 Mine with a little problem.. The gun don´t shoot and the BB´s drop out the barrel. Some suggestion ? Link to post Share on other sites
swatti Posted October 25, 2013 Report Share Posted October 25, 2013 Compression issue? Pistonhead maybe broken. Does the bb "fall" out or fly like 1 feet when you shoot? Ps: nice pics inc soon'ish. Link to post Share on other sites
kojak Posted October 26, 2013 Report Share Posted October 26, 2013 Is that 'block' of metal on the back of the receiver on all the SY/ A&K clones, or just the one with the fake wood grip with screws in the side? I want to install a RS pistol grip. Link to post Share on other sites
swatti Posted October 26, 2013 Report Share Posted October 26, 2013 Any ive seen or heard have the block. Saw it off and put in big screw from the inside. MZ "gearbox" is also a solid option. You may need to make threads for an adjustable hopup depending what generation mz-shell you have. Rs-grip is going to need minor modding too but nothing too difficult.

kojak Posted October 26, 2013 Report Share Posted October 26, 2013 Thanks! I bought one yesterday and they gave me the fake wood version by mistake when I had asked for the real wood, I'm exchanging it today and was wondering if I shouldn't get the EBR stock type instead to make a RS conversion easier.

swatti Posted October 26, 2013 Report Share Posted October 26, 2013 Id take the EBR-stock. Should quite decent as it is or atleast till you swap it out. Can you link me the gun? I havent seen the current models out there. Planned a bit. Saw the block off. Drill a hole in the rear, put large screw thru it with wide washer at its base to widen the stress. Then pick a small bit of metal tubing, add threads to it and attach it to the screw stickin out of the shell's back. Voila, mz-style "adapter" for rs-stuff. Link to post Share on other sites

I havent seen the current models out there.... EBR short: http://www.evike.com/products/41095/ EBR medium: http://www.evike.com/product_info.php?products_id=36442 Fake wood: http://www.evike.com/product_info.php?products_id=31211 Real wood: http://www.evike.com/product_info.php?products_id=32820 All of the above are the same Shun Yang clone with different externals. Evike reused the plastic stock pics for the real wood model; the pistol grip has a single large bolt in the back instead of side screws. I'm in a hotel right now with no tools but I'll post a photo when I get home and take it apart. Link to post Share on other sites
Aod Posted October 30, 2013 Report Share Posted October 30, 2013 They simples roll out barrel.. It´s point the muzzle down and the BB´s roll out barrel. it's likely that the piston has broken as they are wont to do on these models from time to time, especially with the giant springs they put in them. The G&P piston sets are 95% compatible, needing only minor filing to work perfectly. Link to post Share on other sites
RodrigoMF Posted November 1, 2013 Author Report Share Posted November 1, 2013 This G&P parts are compatible with Maruzen guns ? http://shop.ehobbyasia.com/g-p-m870-6-08mm-inner-barrel-with-hop-up-chamber-set-230mm.html http://shop.ehobbyasia.com/g-p-m870-piston-set-a.html Link to post Share on other sites
swatti Posted November 5, 2013 Report Share Posted November 5, 2013 They are compatible, BUT DO NOT USE THOSE BARRELS! They are poop. Just use a TM-type AEG-barrel and TM-bucking, better yet, R-hop it. You know those small brass-rings that go between hopups and barrels in AEGs? Put one of those in the front of the bucking to work as a spacer to fit it better. I have AEG-barrels in both of my shotties with R-hops and my god, they are good. That G&P cyslinder WILL WEAR out fast. The ACM-cylinder has metal part where the G&P is fully plastic. --------------------------------------------------------------------------------------------------------------------------------------------------------------------- Some questions regarding the "issue" with bbs fallin out of the barrel: When you shoot, do they fly out? At all, for like few feet maybe? If they fly out few feet, it may be a compression issue. If the gun sounds normal'ish the PISTONHEAD may be the issue, these can tear and thus no pressure is generated, only small breeze that throws out the bb If the bbs fall out when you point the barrel down, the hopup-bucking, that actually is only 1x2cm piece for rubber has most likely been blown off or dislocated. A functioning hopup should keep the bb in the barrel. --------------------------------------------------------------------------------------------------------------------------------------------------------------------- Oh, and as promised, some of my work. [/img] Cocking-arms, STEEL BABY! Fits nicely to the original pump-handle. Need to weld in one more part tho. the small bit that works as safety when the arms are not fully forward. Also steel as the arms would eat the original pot-metal part next to it. Last is the part locking the arms forward when ready-to-fire. Also steel, makes that nice metallic "klak" sound when cocked. All hand-made. Next in my to-do-list is the cylinder, piston and spring-quide. Link to post Share on other sites
Multicam_Pegasus Posted November 9, 2013 Report Share Posted November 9, 2013 I bought an all plastic one of these a while back for £10-15 (can't remember now!) Came with 4 mags, two stocks two for grips and a tac torch (led aluminium jobby) 450fps on .2's I absolutely love it, sold it to a mate who goes to CQB sites more than I do and made a £5'er profit. Might pick up one of these metal ones though... Link to post Share on other sites
kojak Posted November 9, 2013 Report Share Posted November 9, 2013 Has anyone swapped plastic parts onto a metal gun? Honestly, all I wanted to do was put a RS grip on mine and carry it around as an emergency backup, but the substantial weight of the metal/wood version makes that too impractical.

swatti Posted November 9, 2013 Report Share Posted November 9, 2013 Back-mounted holster should solve your weight-problems... Well, gun-related atleast. From above the gun is quite slim, molding a holster out of Kydex or regular plexi-glass should be quite easy. -------------------------------------------------- My gun is now "complete" and pics should follow soon.
