CMMG Banshee barrel length

Post by 5Jeffro7 » 04 Mar 2019, 17:17

Very seriously considering getting a Banshee in 5.7 (that would be the MK57).

not interested in doing the SBR thing...AT THE MOMENT..., so a pistol it shall be....

prefer NOT to go with just a bare buffer tube, so the 100 series is OUT

I like the looks of the 200 series, 8" barrel with the arm brace (part number is 57A247C)

seems like the only differences between the 200 & 300 series is that the 300 (part 57A1843) is only (for now) available with a 5" barrel and has the added feature of a "no charge" cerakote color to choose from

Considering that I'm eventually going to form 1 it to an SBR, and add a suppressor, is there any particular reason to go with one barrel length over the other?

My thoughts on the 8" barrel is that even with a suppressor of about 6", still looking at the equivalent of 14" of barrel(+suppressor)...and I'm thinking that the additional 3" of barrel will not only give a slight increase in velocity, but help a little with accuracy.

if there's not really going to be a significant difference in velocity/accuracy, hell, I'll pick one up in 5" in about a week...otherwise, I'll have to wait for the 8" barrel in the 200 series to be released.

I appreciate all input from those far wiser than myself

The 8" version I reviewed had velocities very close to P90 SBR.

barrel length probably matters more than pistol/SBR classification, but was it an 8" pistol you reviewed?

Yes. the SBR wasn't available for me to review at the time.
