SIG 516 barrel swap?

Hello all,

What is involved in swapping a 14.5" barrel for a 16" one in a SIG 516 upper? Are there compatible AR barrels, or must I find a SIG-proprietary one? Regardless, I will have a skilled AR armorer do the work.

Thank you,
Ian

I had a bit of a discussion on this awhile back. If you ignore the discussion of the semantics it tells you the work needed.

Probably easier just to perm. pin a flash hider or comp on there.
