  1. KWA Kriss Vector Infinity Build - infinite firepower for your GBB Vector for whom you can't find good mags anymore! This works for all KWA GBB mags btw. Supplies needed: -CQB Russian HPA adapter valve for KWA fill valves -Any Electric autowinding box mag (I used A&K M249 mag) -CA Glue and Zip Kicker (optional) -JB weld epoxy (the tubes, and faster cure time is better) can be found at walmart -Ideally 1*7.5*1000mm steel extension spring (I've only found .5*8*1000 and that worked for me https://m.aliexpress.com/s/item/32812313986.html?spm=a2g0n.search-cache.0.0.70bc08b9FMNRwW#autostay) You might want to double check the minimum diameter of the bottom of your mag's bb reservoir using a micrometer/calipers because all mags are different. Also spend time trying to find a spring with a thicker wire diameter than the 0.5mm that I used, because it's pretty slinky. It's tough tho. If you do, *please* link me it. 1. Install the HPA Valve and take out the spring and guide assembly out of your mag. 2. Insert the extension spring into the bottom of your mag until it stops. Make sure you take out the reservoir parts before permanently fixing this spring in. 3. Use CA glue+zip kicker, or JB weld along the contact line of the bb reservoir and spring to affix it into the reservoir 4. Take a >1in piece of rigid tube that's wide enough to slide over the spring. I find larger plastic pen barrels work, but you can use anything you want. Slide it up the spring up to the bottom of the mag, and apply generous amounts of JB weld to the magbase-tube connection. 5. Optional, but use some kind of flexible rubber tube to slide halfway over the tube you just glued to provide some play in case the bottom of the mag is pushed against something. You don't want your spring to get bent out of shape. I used the rubber grip off the pen I used for the previous section. Tape of any kind should be okay. 5. Take an electric box mag and JB weld the feed spring on it in a similar fashion. You may need to remove the release lever on the mag's feed lip that keeps BBs in, or remove the feed lip totally. On my A&K M249 mag, upon removing the mag's top part that clips into the gun, there was already a metal spring with a widened portion that I could stick my spring into and glue it. 6. Splice and solder adequately long (3 or wires onto the pressure switch for your mag, or if the mag doesn't have that, disassemble it and splice/solder the switch wire onto the segment of positive wire coming after the switch and battery. 7. Tape the switch onto your gun wherever you like. 8. Use 3+ ft of 3/4 in or wider plastic wire conduit (flex tubing) to wrap around your hpa/bb/switch lines. It's the stuff you see wrapped around the wires in your car's engine bay, you can get it at NAPA auto parts and sometimes Lowes or Home Depot. You can also use other stuff like mesh tubing as long as it protects your lines from snagging. And BLAMO, now you have INFINITE firepower from your Vector without paying $100s for new mags!
  2. Hello, I have a TM Five Seven and it is not firing correctly. The main problem is that the piston/loading nozzle is not moving smoothly. It sticks and has a lot of friction. For a GBB to work properly, I know this MUST be smooth as butter. I found faint scratches and wear on the piston plastic, so I am assuming it is the bbu/blowback housing that is the problem. I took a file and steel wool to it several times in an attempt to remove any burs, but it did not fix the problem. It looks like I need to buy a new blowback housing. Does anyone have information on where to get a new bbu, or maybe a fix for this problem? Is there any way I can acquire just the blowback housing? I have searched for days trying to find one for sale, and apparently Tokyo Model company used to sell it, but I looked on their site and didn't see it. DogTag Airsoft sells a whole upper slide assembly for just over $100, though. I've asked multiple airsoft craigslist groups to no avail. Couldnt even find anyone with a five seven. I have lots of upgrades on this gun and I don't feel like spending a ton of money to get a new slide assembly with a bunch of parts I don't need. P.S. The piston is worn at the riders and that may be causing friction, but it doesnt feel like that's where its really coming from.
