Stiffi (aka Site Manufacturing) is preparing to release a new barrel called the MF. MF stands for metal free because this barrel does NOT have have an aluminum adapter on the back where it threads in to the gun. This is a one piece barrel from tip to back, all composite, and is hand made at the Stifii factory right here in the good old US of A.
The MF barrel will have .689″ and .691″ bore sizes. Stifii is using a 5″ Stepped Bore design on their barrels.
They’re only available in black gloss, 14″ lengths and threaded for Cockers or A5’s.
Of course you get the same high-quality construction that you’ve come to expect from Stiffi and this one’s at a great price too. MSRP is just $69 and street price should be just a little less.
You can purchase Stiffi Barrels here.
