I have tried to put an A1 heat guard on a DPMS A4 upper. I have a triangular end cap, but the A1 heat guard seems too big to fit it. I'm not interested in an A1 replica, I just like the feel of the triangle better. What parts do I need to place that heat guard on an A4 upper? Also, are there any other kinds of triangular-shaped heat guards out there for AR-15s?
