Solid Construction, Easy Installation, Adjustable, Folds up with the touch of a button
Weaknesses:
cannot use a rear velocity adjuster.
Review:
This product is very well designed. The folding mechanism is very solid, and when locked in either extended or folded position, it holds the stock in place with no shaking or rattling.
The length is adjustable, from a minimum of 11.5" to a maximum of 14.5" (from the rear of the gun to the rear of the stock)
When folded, the stock locks into position along the right side of the gun. Overall length when folded is increased by a mere 2". Very solid.
As far as aiming goes, the stock greatly aids in keeping the gun stable. Although as others have mentioned, some mask modification, or raised sights will be needed as the angle needed to sight down the (stock) marker sights is both uncomfortable, and with most masks i know of, physically impossible.
Finally, it looks really cool.
Conclusion:
Great product, I definitely recommend this to anyone considering getting a stock.
