Re: Quad rail for ar15
Researched and found out my dilemma. I bought it at a show in phila. I was not aware that there was a different quad rail for a carbine, mid barrel and long barrel. Now, looking at model number it is MAR4L. The L standing for long....Little did I know they have a MAR4S (short) which is what I need for my smith & Wesson m&p sport. Their box just said ar15 quad rail. Now I need to find somebody who can use the long one.......it really doesn't look like a bad piece. Machine work pretty nice.
