Question: Would this fit well on a Browning 20 ga BPS butt stock?  Or would it be too loose?
Document: Overall I really liked the quality and look of the shell holder/product but I just wish it would have been described better. It does NOT fit a 20gauge Remington 870 very well. very loose and unusable if you have a 20gauge. It would fit a 12gauge because the butt would be thicker therefore making the sleeve tight around the butt stock.
I bought this for the obvious reason that I wanted to carry extra shell (is there ever enough?). Some have said that it is loose on the small side of the stock but I didn't find that at all. It fits very snug on a Remington 870 Express. Just what I needed. I would purchase this again if I needed another one.
It is a little loose on the smaller end of the stock, and I think it should have been slightly more tapered. However, it is a generic one-size-fits-all item, so it's not a bad fit.
Fit gun great when installed on a short stock. It holds the right number of shells too. Would recommend to friends.
I like this and rated the shell holder four stars... and let me start off by saying I bought this at Sport's Authority, not through Amazon, but it's the same thing. It holds 12 gauge shells very securely, and fits well on my Remington 870 Express 7-Round... though it is a touch loose on the forward end, as the elastic isn't completely stretched because the stock is too small where it meets the grip.
Did not quite fit the stock of my 12 gauge, but serves its purpose. Holds the shells snug and has a nice tactical touch to it. I would recommend
This holder does fit around a standard stock (Mossberg 500), but it does not hold in place. The sleeve rights up to the palm grip on the stock where it gets loose and the nearest shell will move around. To get around this I have to let a little edge of the sleeve hang off the rear end of the stock. This is not ideal, i will be keeping my eye out for a better holder.
This fit my gun stock OK after some work to get it on. I actually had to put it on in reverse of how you would take a sock off inside out.Not the best quality, but a good value for the price.
I bought this for my Mossberg 500 turkey shotgun. Why they don't make these to actually fit snug on the stock I don't know. The part closest to the trigger is a little loose. I'm not an avid hunter or anything and mainly use the shotgun for shooting clays and home defense so not a huge deal. This shell holder doesn't slide down or move it just looks a little shoddy.
Very Nice product. It is as advertised, a fairly well sewn together shell holder. The best part about this product is the price! At a department store this is easily 20 bucks or more!! !
