[ARCHIVED THREAD] - Carbon Fiber Handguard Modification

Since nobody makes a midlength, I want to cut down a full length. Anybody try this? How hard can it be?

I cut down a Clark carbon fiber handguard for my latest build.
Not hard, just take it slow.
I wrapped masking tape around the tube (check for squareness), then used a hacksaw and gently cut.
The end required very little sanding.

If I remember correctly, the carbon layers are epoxied together. So this shouldn't cause any integrity issues or chance for future fraying or warping, right?

If you use a sharp blade you shouldn't have any problems.

Just be sure to work somewhere where you can set up a vacuum to capture all the carbon fiber dust and wear

a well-fitting dustmask.

When Kevlar burns (one of several different types of Carbon Fiber) it produces toxic airborne near microscopic fibers that embed in the lungs, NOT that you're going to be burning through your carbon fiber handguars. Really don't know how dangerous the fibers or residue is from sawing / cutting other types of carbon fiber is, BUT, I would follow the above advice and NOT risk it. Unless you have good proof otherwise, have a filter mask on at least, and make sure all the fibers are vacuumed up / cleaned up, before taking it off.

Its really easy with the clarks hand guard, i did it a few months ago and love it. I used JB weld for the bonding agent and it holds very strong i just had to take it off to put a new barrel on and it held through all the torque i could put on it with a pipe wrench.

I used a hack saw to cut the hand guard and cut it a little longer than a normal hand guard it work out very well and it is extremely light.
