I was in a gun shop that I hanged out back when I worked part time and a lady comes in with a 20ga 870. Dad died she didn't like guns wanted to get rid of it, he gave her $95 for it, as soon as she left I asked ro see it and asked what he wanted for it he said $175 and I told him I had $125 cash...
That linear comp works great with sound reduction @ the shooter,. I have one on a 556 and I could shoot it without earplugs. The holes in the front through the muzzle blast forward
The load my Savage likes is
55 grain bullet
25.0 grains of h-335
C.O.L. 2.260
I got a 4 shot one hole group with nossler ballistic tips and sub moa with other 55 grain bullets (remington sp, and siera sp)
Hopes this helps
