I just got my Omega 9k yesterday. It came with a 5/8x24 direct mount. And the end cap also. Since I am going to use this on my Glock 17 and B&T APC9k . Using the threaded barrels on each. I am wondering what is the best option for mounting. Should I use the 1/2x28 piston and included end cap? Or should I go with the Alpha 1/2x28 direct mount? I have an Octane with three lug that I use on my Evo and APC9. now.

Tilting barrels like the G17 need the piston.

A direct thread mount or piston with fixed barrel spacer is needed for a fixed barrel PCC.

Running the piston on a fixed barrel runs the risk of a baffle/end cap strike.

Thank you,
I am going the piston and spacer route.
