Reply #20: There a bunch of different styles,

[necso]

but I have never been to a store that had more than a small number of choices.

An expandable (slides) stock should be OK if you can get one of the right length. I believe that most are zero or full extension lock only, but I see no reason why there couldn't be intermediate positions if you designed it that way. But, hey, I like the folding kind.

Personally I have never liked that "wire" style of extension. I like something that I can use with just a hand hold, then in a few seconds move to a shoulder position with a real butt. I think that they balance better too.

I also like a front rig, and a folder drops a bunch off of the length and helps with balance.

Pretty much I insist that any modification to my guns, (that is a matter of "taste"), can be undone.

In any event, I couldn't find the banner that you are talking about, but, if you are willing to pay the coin, I am pretty sure that something can be found.

If you can give me some idea of what you are looking for in terms of collapsed and extended lengths, I am willing to look around a bit.

You should probably give me overall lengths too, because sometimes that is the way they talk about it.

The 88 and the Mossberg 500/590 take (some of anyway) the same aftermarket buttstocks, don't they?

I am thinking about another 12 and the 88 is on the possible list.
