Hey, just recently purchased a poly M305 full length and after now joining this forum I'm wondering if I got myself in over my head. I picked it up for $399 new thinking I had a cheap little plinker to play with but after reading one too many posts on here about these chinese rifles blowing up in faces I'm wondering if I made a big mistake. Wasn't planning on dumping cash into this toy and tinkering to bring her up to code. Are these rifles really that bad?
