Dissipator

Old A2 receiver from a trade. 

Joe Bob Outfitters mid-gas 1-7" barrel from eBay

Hogue rifle length free float tube bought used

Recycled FSB

Used A2 flash hider

Drilled out the taper pin holes on the FSB with a 5/32" bit and tapped the holes for 10-32 knurl point screws.

Broke two cheap strap wrenches trying to get the gas tube holes in the barrel nut and upper receiver aligned. Resorted to a redneck solution to avoid buying a better strap wrench for one job.
