Mossberg barrel device of some sort
I recently won a Mossberg 144LSB at an on-line auction. The auction pics weren't the greatest, but I could tell there was something on the end of the barrel that I've never seen.
It arrived at my FFL dealer and I got a few pics before it went inot his safe for the "10 day cooling off period".
It is in pretty decent shape, with a sling, sights and a magazine
The knurled knob appears to be a thread protector for some fairly course threads. Does anyone have any ideas about the thing on the muzzle?
Thanks
