Modding the airsoft quad-rail (how-to)

[MP_OHIO]

a foregrip would be cool if you didn't hinder the barrel movement. That is the only reason I took mine off. I ended up putting too much crap on it and it threw my zero off. I like mounting my laser above or below the barrel as it has better accuracy that way. You can adjust up and down by eyeballing it easier than left or right.

That's why I got a smaller EOtech (XPS2) and put a unimax on my optic rail. I got tired of that 2 axis thing too.

O.K. you sold me. I just checked the link you provided and it beats the heck out of the one I had that sold the same kit for over $120. They have the price down to $22 but then theres the shipping, etc...

Have you looked at the replacement trigger?

I just got mine in and the pictures do not do it justice.

Thanks again. You are a life (and money) saver! :P

I found this thread after I found the airsoft quad rail and was wondering if anyone had tried it. Thanks for posting this!

I did not have to adjust the screw holes that attach to the threaded fillers that fit on the stock. However, I did have to install a screw and bolt on the side rails. If you notice, the holes toward the stock near R13 and L13 are larger. I found that the provided screws didn't thread in like the rest of them and the rail was not 'rock solid'.

Finally, I stripped one of the screws in the round spacer piece after grinding (not drilling) it out. I believe I am going to get one of the fake suppressors and use that as a whole barrel spacer. I'll let you know if it works.

Thanks again!

Has anyone tried an Airsoft rail with a Moerse barrel shroud? I'm not planning on SBR'ing my PS90 so I ordered a shroud, then I realized a rail would solve the lighting problem I've been agonizing over (personal preference, I don't like tape switches). If the Airsoft version won't work, I'll go with the MPFTech.Thanks for any info

Thanks! Sorry for the lack of introduction but my internet has been crappy here tonight (I'm in Afghanistan, contracting).
