Well I didn't fare any better with the gun I decided to purchase instead of one of these duds.
I picked up a beeman 2028 Marshall, and it was so inaccurate I couldn't even shoot it outside without fear of it slinging a pellet off into the abyss.
It was bought ad a project, so I had already muddled with stuff so there was no returning it. I ended up having to recrown it 2x, scrub it out more than any other barrel I've ever received, polished and chambered the leade, remove a burr from the transfer port, and polish the barrel about 40 strokes. Now it'll give me quarter sized groups at 25, but I did make it into a carbine. 20 shots at 18 fpe.
