Guys, I am not really up on all the AR accessories so I need your input here.

I bought an aluminium FF triangular forend a few years ago and never used it. I always thought that it was a little heavy and bulky. So anyway I got a flashlight at P&D a couple months ago and I was thinking of mounting options, and a tiny light bulb came on in my head. I could clamp the forend on the mill and then mill 3 picatinny rails on the peaks of the triangles. This would give 3 rails at 120 degrees apart.

I don’t want to spend $300 or $400 on a factory made forends w/ rails, and to do this, my time is free on my lathe and mill.

I really don’t see any problems with this not working, but has anyone already done something like this and had problems? Or can anyone foresee some problems? Uncomfortable to shoot, etc.

So give me your 2 cents.

Thanks …. Darren
 
Hey RePete;
Thanks for the link, I know I have that site somewhere, but I would have had to search for it.
There is lots of meat there according to the drawing. When I was comparing it to the riser that I have I thought it was going to be close, but now I realize that on the riser, the dimension on the flats (under the angles) is deeper to allow the riser clamp to seat . If I knew how to post a pic I would.

The walls thickness at the smallest dimension is .102” and I won’t touch that. Where I am going to mill, I will probably take it down to .175”.
