-SOMETIMES the inserts are not way they say they are. I never had that problem.
Received the Freak Jr. kit as a gift. Wasn't expecting it, but I had no barrel for that weekend, and my dad didn't know any better. He went of the local shop keepers advice. Went to play. One break in about a case of paint. Shot straight, and accurate. I actually love the barrel kit. Probably the only Smart Parts product I'll ever use ;).
