I know this is a old thread but feel compelled to talk about my recently purchased yl-12
The 1st one I got I sent back for a out of spec receiver, barrel wasn't sitting straight. So I exchanged it and the 2nd one I got is perfect. Action is very smooth and feeds everything I put in it. I love the gun for its simplicity. I honestly can't foresee any complications with this gun and am extremely happy with the purchase. On a 2nd note I also had a maverick 88 and it also performed well. I sadly traded it for a DA grizzly mag and regretted it. The DA was just to dam heavy so I got rid of it. I prefer the tube mags on shotguns, may not look as cool but to me they are a more practical shotgun
