One of the brothers has a few AR-10 carbon fiber hand guards, wants to use them on AR-15s
Worked up a prototype this weekend.
Started with some thick wall 6061, bored and turned to spec and a JK Ultralight barrel nut.
Looking things over.
On to the rotary indexer for some holes and a slot. Ended up not using the larger countersinks. Just part of prototyping. Call them lightning cuts now.
Some graphite black cerakote and ready to assemble.
Never handled a really nice CF tube before, weight comparable to about three hummingbird feathers. Thing of beauty.
