I just bought 2 not long ago. This one was installed and tested. It is in as new condition and back in the wrapper. They cost $28 plus shipping.....I would like to see $25 shipped out of it. It's like ordering a brand new one and saving $10 by the time things are said and done. It's a real nice gip...I'm keeping one for my Bullpup, but decided I don't need both.
After looking at the the pic.....mine has a standard slotted screw, not an allen head style. That's how it came.
