    A little work went into getting the pin to seat into the slots, but that’s just some basic dude stuff to make it work.

    This does the job well, however I looses the adjustable lever to put it on my gun chassis, and the level is loose now. But it does the job!

    Cheaper stock but not overly bad. Had to open up holes on the chassis so I could get positive lock on the stock detent lever. Other than that for the price it will get you started

    Being that this came from the same company I would have expected that it would work correctly. The lock pin didn’t fit into the lock holes in the tube. I fixed it by drilling out the hoes two bit sixes bigger. It all works great now.

    The stock is great but I wish I could figure out how to “tighten it up” a little. But it is pretty good.

    I had a small issue with mine after some use, the roll pin had to be knocked out and I readjusted the tension. After firing a round it sometimes would slide to next position. More tension resolved this quickly & easily.

    It was a little difficult to slide the stock onto the chassis, as the adjustment lever didn’t allow the pin to be recessed into the stock. Come to find out the release works both ways. To adjust position, you would squeeze the lever and to remove the stock you need to push ( Down) and slide it off.
    Another issue is the holes for the stock adjustments aren’t large enough to accept the pin to ” lock” it into place. I had to drill out the holes, in the chassis, with a 21/64th” bit. After this was done the stock was LOCKED in any position.

    Ok, butt could have a plate over it to prevent it from positioning too far forward or a thin rubber pad, feels incomplete.

    Sets up perfect with the chassis.

    Unfortunately every time i shot, the whole buttstock goes forwards. I quadrupled check everything on the buttstock and it looks like the pin slides out when i fire one shot and makes the whole thing slide forward. Very disappointed on that product.

    Great piece. The detent would not fully clear the stock so I had to file down the end of the receiver butt stock mounting tube in order to get the stock on. Very easy to do.
