I'm going to say yes, an LT is an LT. The magnum receiver may have a slightly larger port which would not affect regular size ammo. The 2 & 3/4" barrel should have sufficient port area to cycle if it's anything like the 12 gauge engineering.
please send me a close up of the receiver where the scope mount is on the gun, or was mounted, does the scope come with the gun. I am interested please send me some better picts. thank you victor can you please call me also @ 330-429-7996
