[ARCHIVED THREAD] - CMMG Evolution question.

Does anyone know if a spikes dedicated barrel collar will fit on a CMMG Evolution 22 kit? I have a spikes upper and I want to buy an evolution kit to use in it! Thanks for the help!

Collar will fit. Live round extraction may or may not work as it is a function of the collar in the CMMG kit.

What does the collar do for the live round extraction?

It's in the machining.

If you have a tight chamber in your Spike's Barrel, meaning 0.227-0.228,
live round extraction has a good chance of working. The collar is another
factor, depending on the barrel / collar fit. As long as it is a reasonably tight fit
you'll be in good shape. The CMMG collar uses a ball detent and is pretty much
locked tightly to the barrel.

Did CMMG change from .460 to .500 collars/barrels?
Unless CMMG went to .500", It won't go on anyone else's barrel.
Never mind, I'm distracted.
Shadowcop has it nailed(again). Collars are essentially interchangeable on bolts.

The collars are interchangeable.. CMMG is using a ball and detent on their 0.460 collar and barrel and it works great.
