This is a rough prototype of the M4-SD II. It is not the same outer profile, but is the same product internally, except for a bore .005" larger than the production specification. In other words it is louder than the production product will likely be.

Also the 14.5" barrel is louder than the 16" barrels most people use for testing suppressors on "rifle" barrels.

I apologize for the wind, it's windy in Wisconsin.
