King Arms CASV fitment on CA m4?!

Junky · September 19th, 2008, 00:49

Hey guys and gals.

I am currently putting together my first AR project, the main part of it revolving around a CASV rail system. The gun its going on is a CA, right now a stock sportline. I've been looking at the KA CASV rails on various web sites and im seeing on some of them that it doesn't work for CA guns?

Can someone tell me why, aswell as what i might need to change to make it work?

I will be buying a metal body for it anyways.. will this fix the issue with the CASV fitment? esspecially if its a KA body?!

THanks!

The CA receiver top rail is a little taller than most AEG's (plastic or metal) so some front ends won't match up (ie: you need to the foregrip top rail to be in line with the receiver top rail).

Most other metal bodies like G&P, King arms, Dboys, etc.. have a fairly standard / consistent top rail height, so most front ends will work on it. It probably won't fit on your CA.

The CASV is held onto the gun by slipping the upper portion onto the barrel nut; you therefore need a realistic style barrel nut, like this:

The rest is just attaching the rear portion of the CASV to the upper receiver's rail.

As long as you have the right barrel nut, I can't think of why it wouldn't fit. You can buy those barrel buts (for airsoft) separately.

The gun also probably needs to have a one piece outer barrel (i.e., I'm not sure those barrel nuts would work properly with a stock Marui M4A1 barrel).

alright so it is a body issue then. Easy enough to fix, im sure il get a new delta ring set aswell.

Anything else? anyone with some first hand experience???

If you're getting a metal body and a proper delta ring, there really shouldn't be any issue.

I have first hand experience with the KA CASV (I still have one) and CASV in general (has a PROUD one before that), but not with CA M4s.

Ok well i guess il get the body, ring set and CASV and see what happens.
Thanks!

THoughts on what everything you need is in the few posts before yours

I was asking if anyone managed to make a replica casv fit on a ca m15a4 carbine and what modifications were used. Is that so hard to understand jayhad?

I have experience fitting one on a magpul body. Took some serious Dremel 'persuasion' to fit on it but now it's nice and sturdy. If the rails aren't to spec with the average RS M4 upper (which they aren't on the magpul), then you'll need to work some voodoo to get it to fit. If the upper is to spec then you're sitting pretty. Good luck, the CASV is definitely worth the hassle and effort to mount.

What's this about having to mod the magpul receiver?

And by the looks of it I'm guessing you can't put a rail mounted M203 on there without it looking REALLY bad
