Questions & Answers
Will this work in a panzer m4

yes it will fit....but the panzer magazine is 1 inch to long. will need a spacer or a real benelli magazine tube. I tried the real (thats what sellet said)benelli magazine and the threads were not compatible. so I will probably have panzer mag tube machined to proper length

is this version ported?

part numbers starting with BRBMPB are ported - example BRBMPBBKSBS is ported black SBS barrel
part numbers starting with BRBMNPB are non-ported - example BRBMNPBBKSBS is non-ported black SBS barrel

source: https://www.blackrivermfg.com/product-page/benelli-m4-14-barrel-sbs - select a color and ported or non and the part number comes up

Product Info for Black River Manufacturing SBS Benelli M4 12 Gauge Ported Shotgun Barrel

Upgrade your Benelli with Black River Manufacturing M4 14 in barrel. ALL NFA RULES APPLY. Black River Manufacturing barrels are drilled from 4140 steel instead of 4130 which has nickel in it which makes it softer. 4130 is used because it can be extruded to make barrels to cut down on costs leaving you with a low quality barrel. Theirs are drilled from 4140 to ensure the highest quality possible.image
