Replacement shroud tube and back plug.
Shorter one will fit all weapons that have 4-3/4" of barrel to cover with no obstructions
Longer one will fit all weapons that have at least 5-5/8" of barrel to cover with no obstructions
For the shroud to fit inside your hand gaurd/rail the opening of your rail must be at least 1-1/2" inside diamter.
We suggest the following for you gun as long as they meet the above specs also
- Standard carbine AR (can be short also)
- MP 15/22 that has a THREAD ADAPTER installed on an non threaded barrel ( Perfect fit for these guns with adapters. fits tightly inside the front dust cover area**)
- Standard carbine AR (can be longer also)
- MP 15/22 with threaded barrel (PERFECT length for these guns)
Sizing Tips Video
5-5/8 " Is the perfect size to fit on a M&P 15-22 Sport model and stops just shy of touching the hand guard end cap. The tube is a bit shiny so I plan to dull the color with Krylon paint but the added weight is perfect to add to my rifle to make it a better trainer. Plus the looks are awesome.
