Just saw one for the first time at the gun show last weekend.
What to the folks here on the ARFcom think?
It looks kinda neat, but I have my doubts on how well they will actually work out there in the real world.
TIA all opinions and comments,
I bought one of the adjustable ones. It worked great, but started leaking oil after about 100 rounds. One of theese days I'll send it back for a new one.
