I mentioned my idea for a new style of Carbon Fiber Handguard on another thread, and some guys showed some interest.
I thought I would start a new thread to see if there is any interest in me making a limited run of these.
I had a CF HG with threaded rings glued into a carbon fiber tube. It was then threaded onto a free float barrel nut. A locking ring is then used to tighten and "time" the HG.
The tube is only supported by .75" so it has a little flex. The locking ring also doesn't look the greatest. It works, but it can be better.
My idea is stronger and seamless, however, it requires the end user to do a little work.
Design:
1. Standard Free Float Barrel Nut: Any make will do. Will need to standardize since each company has a slightly different thread on the OD.
2. Aluminum Adapter: The OD matches the ID of the CF Tube. The ID of the adapter has threads to match the free float barrel nut. It also has an internal lip to tighten up against the barrel nut.
3. 2" OD Carbon Fiber Tube - these can be purchased from a few places online in 6ft sections. The tube can be cut down to any length. The end could even be cut back at a 45deg angle or anything else to add style.
Installation:
1. Assemble free float barrel nut per standard method.
2. Tighten Al adapter onto the barrel nut hand tight or with a strap wrench.
3. Slide the CF tube onto the adapter. Aligning any added rail sections or sling studs.
4. Mark the tube and adapter for alignment.
5. Take the adapter and tube back off of the rifle.
6. Glue the adapter and tube together, taking care to line up the previously made marks.
7. Let the glue dry.
Key points:
1. The adapter supports about 2.5" of the CF tube.
2. The lock ring is eliminated.
3. The tube is perfectly centered around the barrel.
4. The HG can be removed for work on the gas block.

Standard end caps can be glued in the front end of the tube.
