Machine operations not complete.


Just has threads but is not milled for the piece that goes between it and the upper. Can't be properly installed.

Close but no cigar

Build quality and finish of the buffer tube are great, but it's to large in diameter to work with the GearHead Works Mod 1 Tailhook brace. PA doesn't list the diameter of the tube in the specs which would be a great help when ordering.
