So speaking of hammerhead barrels and fins.....
Techt make an Autococker to hammerhead adapter to use with the ifit system.
Does any one see any benefit to using this vs the hammerhead fins? If one already has the ifit they won't need the hammerhead fins.
Little bit longer? Shorter? Before rifling? Better fit?
And even the 20 in hh uses fins correct?
Anyone got a close up picture of this?
