AL Barrel Nuts, Alloy Handguards and Heat

[A5BLASTER]

A5 meant galling, on the threads surfaces. Bill A is the expert on bbl nuts and torque, upon his beloved Grendel idea. 60 ft. lbs., is max.

Never use any heat to separate, aka- a bbl. change. Kroil oil- seep- soak - wait-

Shoot less quickly, don't overheat all the components-- better groups on target.


Galvanic corrosion is the result of aluminum and steel connectivity- Not good, Bill A reduced that by using the Loctite, Permatex threadlocker, as a barrier to the


dissimilar metals,,, and as the lube on the threads.- Plus to help keep all parts together for the best accuracy possible.

Slow the rate of fire for best groups.

Thanks for the spell check Sneak, been a ruff last few days on bed rest.
