Im not much on adding on EXTRAS
But since I was getting Older I did buy a Aimpoint ML2 for one of my Carbines back in 2001. wich sits on my Defender M4 Now
This add on was worth every penny
Since going threw Tropical Storm CHARLIE I thought of adding a RAIL
so I could mount a Surfire light
THE KAC R.A.S.
Fits on just like a regular HandGuard and took me a couple tries to install
No need to Take the FSB off etc.
R.A.S FITS ROCK SOLID!!
And is the Best ADD ON I have Bought for my M4
ANYONE looking for a RAIL thats easy to install must BUY a KAC R.A.S.
And they Look awesome as well
