great addition to breacher 12ga (07/06/2010)

added to a mossberg 12ga breacher shotgun. very well made and has not induced a failure to feed. still allows the breacher 2" at muzzle. replacement spring was included along with the vang comp stainless follower. sling can be positioned left or right side. over all very good.

VANG COMP +1 Ext (22/08/2011)

I too ordered this for my Mossy Breacher. The very end of this extension is about 1/2" behind the breaher's slots, so no need to worry about any powder blasting on the extension itself. It mounts SOLID to the mag tube. I think the other review stated "sling mount works on either side" it does, although you will have to flip the sling mount.

NOTE:
On my Breacher, this extension is ONLY a +1 with 2-3/4" shot shells you can get a total of 6 shells in the mag tube or 5 - 3" shot shells in the mag tube.

I had two minor issues with this product.
First the SS follwer had sharp edges all over it, from the machining process, although it was nothing a few minutes with some 400 grit sandpaper couldn't fix.
Second, the inside of the extension appeared to have a thin layer of surface rust. A few minutes with some oil and a wire brush took care of this.

If you are thinking about getting one quit thinking and do.

Later,
D
