VSR w/ HPA mod vs Kjw m700?

Hey guys. Not sure exactly where to post this in,as it concernes 2 guns.

I have the chance to get a King Arms vsr gas chamber, which I would mod to hpa/co2. I was originally planning on selling my vsr in summer, and buying a kjw m700 with a hpa rig.

Cheaper would be to keep my vsr and sell my piston/cylinder/trigger etc. As my vsr shoots accurately upwards of 80m, I'm debating whether or not to hpa it.

Any advice?

Thanks

Well never touched a gas VSR cylinder but I've seen HPA mods on them.
For me it's not worth the fuss dwelling with the VSR, the air line will pass extremely and will attach directly on the bolt which is ugly.

IMO a HPA M700 would be better but like I said I don't have experience with gas cylinders.

Not a problem george! Neither have I :P

It looks simple. Just unscrew the valve and attach a hose. As you said, it wont look the part, but neither does a M700 with a hose out of its mag ;)

For me the main (+) on the vsr is, that I can use VSR mags, which means quick reload, whereas the M700 would need refitting or speedloading the mag...

Lets go people...ideas/advice?

I vote for the hpa vsr... because I've never heard of it being done before, and if it works I'd be interested myself.

GO GO GO

Converting a VSR to HPA can be done. But not with those awful CO2 bolts. Attaching a hose where the valve is supposed to be just won't work, as the bolt has to be rotated and be able to move backwards to reset the trigger mechanism, and so the stock will get in the way of your hose.

But I have some great news: Take a look at the system from Mancraft.pl. They have a HPA conversion system for springer SVD, L96 and VSR guns that works great. They also make custom ones for alternative platforms, like ARES WA2000, Cheytac, etc.






The hose goes trough your stock / pistol grip, so you can use a little CO2 tank hidden in the stock (maybe those 12g bulbs) or have a good looking and comfortable line to a bigger CO2 / HPA tank, with no need to disconnect the hose from your mags to reload like a typical M700 air rig would.






Check their facebook and this review.

That being said, I would stick to the M700, AWM and other gas guns, just for the plain awesomeness of having the mag where it is supposed to be.
Rubiksklube, luismx and HERO like this.

wow thanks dimitri!

i have to say tho that its not that much of a problem as the bolt doesnt need to be cycled that far back. I will however take a look at the links you sent me! looks pretty sweet.... I just dont truely understand how it works ATM, but ill find out :)

Thanks alot

Edit: After reading through it, i am truly impressed with the set. Unfortunately, its a bit out of my price range. The vsr conversion would cost 120 Euros. I might get the vsr KA chamber for 50...

Interesting, I have a JG bar 10 so the Mancraft HPA or CO2 kit for a VSR looks good, I'm still a little shaky on how it works exactly.

Does it completely replace the whole bolt cylinder assembly? Like is it a simple install of replacing the normal bolt/cylinder with their version and running a gas line somewhere? Is the CO2 and HPA pretty much interchangeable if you just swap cylinders and change the regulator for the FPS you want?

I can't seem to navigate their website and there is a bit of a language barrier, google translate isn't great either.

I would definitely go with the M700. I just recently purchased a KJW M700 with the Tanaka Long mag and a CO2 conversion rig by Palmers Pursuit. Why? I had previously owned a completely upgraded VSR-11 that was shooting 450 consistently with a .30g and still had trouble lifting the bb and quite frankly I couldn't accurately hit anyone (even when they were standing still) at 180 feet. In my experience, the hop up on VSRs arent great, but on my KJW M700 I am going to make a custom nub, which is something you can't do with a Springer.

Bobcat, I suggest you do some more homework. You can fit a custom nub in a springer. It has been done many time by many people. You can put a custom nub on any gun with a hop up.

Yep, that's a bug with google translate. You can navigate the website if you access it directly via mancraft.pl.

Installation is simple as replacing the stock cylinder assembly with Mancraft's conversion kit, and perhaps making a small hole in the stock for the macroline to go through.

Then you can attach that to your favourite regulated CO2 / HPA rig. They offer their own regulator, connector and gauges also.

Thanks for your input. I kind of understand why you would swap if the VSR wasnt working for you. On the other side of things, I have a VSR which outshoots everyone here on my fields. FPS deviation is +-1.5 fps and I can reach distances of over 100m with a bit of overhop and aiming higher. Talking about distance... I hit a friend of mine at 122m about 2 weeks ago in the neck. I waved at him, he stuck his middle finger up and shouted 'you cant get me' so i aimed for him, and fired. Didnt see the BB anymore, turned my head away, then looked back, and i saw him raise his hand. Hit him exactly in the neck. We laser measured it after with someones rangefinder as we could not believe it happened. It was slightly downhill....so i guess it doesnt realllllllly count fully, but....its an ego boost none the less...

Cheers, so potentially I could get a second cylinder fitted out for the CO2/HPA rig and if it didn't work or if I couldn't get hold of gas at the time I could put the spring one back in and use that....

Does this work with those small CO2 bulbs or has it got to be a large cylinder??
