Anybody know where I could get a set of the older CAR triangular handguards?

triangle CAR hand guards need to be made from rifle length ones. You'll need to get a  front, triangle, handguard cap and the custom large rear, triangle, cap from Ken Drasen at;
Hay River Trading Co.
                         P.O. Box 176
                         Alena, WI.  54805
                         715 357 6054
- this does require removing the muzzle device and the front sight tower for installation.
Also Ken may have complete "kits" available.
