I have the latest MPX 8" and want to chop the barrel so my AB Suppressor F4 non flow through suppressor will line up with the end of the handguard. The length of the barrel will be 3.14" when measured from the face of the bolt after the cut. Does anybody know the shortest length with the cans added back pressure it will function without having to open the port?

If you have chopped your barrel, will you let me know the shortest length you went?

I will be shooting this always suppressed.

I'm not worried about the bullet stabilizing since I've seen the Suppressor used on a p365 with a 3.1" barrel.

Any info is appreciated.

it is normally frowned upon double post. delete one of these.
