New KWA MP7 in need of Npas / power down bolt.
 
Anyone have a good store with a link to where I can find these items ? Spur of the moment purchase and looking to make this gbb an indoor only gun but i would like to add that angry supp. to it. Ideally the Npas putting it down to 300 ish then adding the supp. would get it to around 350 would be great for me.

Thanks in advance.

contact KWA direct, they ship to canada and carry the Low Power Bolt. I'm saving up for one for my MP9 (it's shooting around 450-500 fps on .2s stock... yeah wtf lol)

Only other company I saw with it is AirsoftGI and it was out of stock.

Why do you want to add the Angry Gun suppressor if you want to power it down?

Why not just use the VFC suppressor in that case?

The benefit of that, is not having to take the accuracy degradation that you'll get with the Angry Gun suppressor.

Airsoftparts had some in stock when I was there this past weekend

I agree with that the ANGRY GUN kit INCREASES FPS a bit and can also damage your hop up after a while. I didn't see him mention the AG kit first read through so i was like 'wtf ILLusion' until i reread it lol. If it's purely for lowering FPS, dont get the AG kit. Get a regular suppressor that's foam filled, it might absorb some of the gas and weaken it SLIGHTLY but don't quote me on that.

lurkingknight September 19th, 2013 17:29

the 5ku suppressor is a much better option, especially if you want to keep it indoor velocity. It has no inner barrel extension.

The low power cbq bolt can be ordered from kwausa.com directly. Call or email the pro shop requesting the part they will ask for your shipping info and ship it out to you usps. Don't order it off the website otherwise they'll ship ups.

This theory is unfounded. There's no such thing as the foam "absorbing" power... it's not like the round has to punch through the foam.

When the round leaves the muzzle of the inner barrel, it has already reached terminal velocity. There is no additional compression at that point. Any "loss" in power between the muzzle of the inner barrel and the muzzle of the suppressor is exactly what would normally be experienced in deceleration from that distance, regardless of whether there were a suppressor attached or not.

Reaver_RRTS September 19th, 2013 17:32

Just a quick thought that it MIGHT, didn't say it would, but there you go. Regardless, AG kit is not suggested.

I wanted to lower the fps and put the angry supp. on basically for look and a little bit of a longer barrel. If it will do more harm than good, should I just go to the low power bolt ? Out of the box it says its shooting 370 fps. As long as I can get to 340-350 with very minimal effort ( since its my first gbb ). If an AG kit is the same thing as an Npas cool. I just learned about these things today after picking this gun up.

Just checked out airsoft parts site. Pretty cool place.

The angry gun suppressor is going to increase your fps.

Typically people install the npas or a flute valve ( or low power bolt) to decrease to indoor safe gps and then add the angry gun to bring it up to outdoor fps

Reaver_RRTS September 19th, 2013 18:16

the Angry Gun kit is a built in (but removable) inner barrel that butts up against your current barrel. Over time it damages the internals and will INCREASE your fps. it's the same as installing a one piece longer barrel, it'll increase the fps. it will NOT decrease your fps at all. unless you remove the inner barrel, but at that point, just get a fake one for less money.

His thread. That's whom I'm replying to. Disregard reply if you aren't op. lol

ILLusion September 19th, 2013 18:19

I have a used complete bolt here that I'm looking to sell or part out. It's a fairly upgraded unit, with the following upgrades:

- Action Aluminum Ventilated Piston Head
- Ready Fighter Reinforced Loading Nozzle
- Ready Fighter Upgraded Nozzle Return Springs
- Ready Fighter Reinforced Screw Set
- RA-TECH NPAS Conversion Kit (includes adjustment tool)

I still have all the original parts, so this unit can downgrade this back to stock components if the upgrades aren't necessary.

Contact me for more info.

AnthB September 19th, 2013 18:24

Npas seems to be the easier of the two to install so I'd prefer that . I guess the angry supp. is out due to damaging of internals after time. Though its going to get damaged regardless I may as well stay away from that to slow the process just a bit.

Reaver_RRTS September 19th, 2013 18:27

It'll also raise the FPS too high for indoor anyway, if the NPAS or LPK lower it to let's say 340, the Angry Gun kit would boost it back up to around 360 anyway if not more, depends on temp, gas, etc etc...

On the wide open setting, the RA-Tech NPAS will barely reach 350fps. 340fps is more realistic. Unfortunately, the design does not allow it to go any higher.

Adding the Angry Gun kit on after that, will bring the power back up to around 410fps.

The dynamics of gas guns are VERY different from AEG's. Barrel bore or length increases have extremely dramatic changes to power output.

As an example of this, I just upgraded a gas GBBR's inner barrel, from a 200mm 6.08mm inner barrel, to a 229mm long 6.01mm, and the power jumped up 57fps. That was with a very minor length increase and a tighter bore. Now imagine adding the full length of an Angry Gun suppressor...

AnthB September 19th, 2013 18:50

Seems like ill have to do some reading on what does what for GBB's . Still a rookie but I dont mind reading sessions. Oh btw, is there a walk in store for airsoftparts or is it all orders off the site ?

AnthB September 20th, 2013 20:16

Having a hard time finding 'The difference between upgrading an AEG and GBB for end results'. Anyone have a link that explains it. Not sure if what im searching for is even right. I just want to know about changing internals and how it affects fps and all that stuff . If there is one that's just on GBB I would much rather that one.

NANA September 20th, 2013 21:17

Hero Outdoor in oshawa has the CQB bolt. I picked one up a few weeks ago. Very easy to install (3min) and brings your fps down to indoor levels.

AnthB September 21st, 2013 00:31

Im looking at the site now. Is it a KWA item or like a modified item ?

Another thing. Is it okay to melt the glue off the threads with boiling water? I mean, I could use my torch but i'd rather not.

There are a LOT of threads in the gun.... which one are you referring to specifically?

I'm guessing the flash hider, but generally, clarity is preferred, since nobody can read your mind.

AnthB September 21st, 2013 15:25

yeah for the flash hider. I dont think anything else is glued in place.

ILLusion September 21st, 2013 15:35

I've heard of a number of people removing the flash hider by putting in boiling water. I don't recommend a torch.

AnthB September 21st, 2013 15:36

Cool thanks. That was another thing I was told to do that I apparently shouldn't . haha

A torch would be okay to do if you use a lower heat mixture of gas... and only if you've completely assembled the entire gun so that the entire outer barrel assembly is free of the gun. The concern with torching it while attached, is heat transfer to the sensitive plastic and rubber components of the hop up chamber at the other end of the barrel. Also, radiating heat from the barrel to the surrounding areas of the rest of the gun.

AnthB September 21st, 2013 16:06

Yeah maybe he thought I used a propane torch but its acetylene which would definitely burn up everything rubber inside lol

AnthB September 22nd, 2013 14:58

Still have yet to find the proper npas valve or any cqb bolts in stock anywhere. Damn you gbb!

Have you tried the link I posted? It's not mp7 specific as it is for all KWA/KSC system 7/NS2 pistols and smg's

AnthB September 22nd, 2013 15:58

I checked it out but theres that one that you linked and this one http://www.revolutionairsoft.com/RA-...gbb_p_309.html that i found. There is definitely a difference but I wouldnt know if it matters.

K3vX September 22nd, 2013 17:03

The difference is the long velocity adjusting tool. This one doesn't include it. That means you will not able to adjust on the fly thought the barrel. That's something that I would recommend not doing anyway, but that's a personal opinion...

Edit: I don't know if the airsoftparts version includes any tool...

Reaver_RRTS September 22nd, 2013 17:44

All this talk about the MP7 and seeing the WE SMG8 (not buying it) on a local site made me really want one now.... Ugh! Too many guns already! >.< TT_TT for the tool KWA also has it and once again can be ordered from.

Revoking September 27th, 2013 14:48

Npas for kwa mp7 in stock at Bent barrel airsoft based out of red deer call them up and they can ship it out has adjustable npas unit and long adjuster tool. You need to take of the suppressor if you have one on your gun to adjust but they work extreamly well
