My Schedule 80 AR Grendel

[jackwagon]

Here is another one of my ideas, electrical schedule 40 PVC handguards.
These barrel nuts are $8 on ebay (free shipping) and will get a barrel attached to a receiver for testing purposes.
The 10 ft, 1-1/2 inch pipe, available at Lowes, has a bell end on one end.

It can be split with a hacksaw (2 crosscuts worked best)and directly attached to the barrel nut with SS hose clamps.
I used 2 clamps for redundancy. I wouldn't want the handguard to release accidentally
A union is necessary to make more handguards out of the rest of the pipe without the bell end, unless you made a 10 foot handguard.
I attached the union with screws but PVC cement would be permanent.
I had to cut a relief cut in the tubing inside the union to clear the gas tube as shown in the photo.

I was surprised at how rigid this is when I used it at the range.


Anyway, more options are better, IMHO.

They also make a female adapter( if the threads matched up with your barrel nut) you wouldn't need the clamps, just glue the pipe in. https://www.lowes.com/pd/Charlotte-Pipe-...er/3699086
