11-87 extended magazine

Excellent product with instructions to match. 20 minutes to assemble that included drilling the indentations out of the stock magazine. Highly recommended.

Great addition to my Remington 870

Easy to install. 6+1 is what I wanted for a home defense shotgun. Taking it to the range in the next week to practice.

Excellent product!

I bought this to increase the magazine tube capacity of my Remington 12 Ga 870 Express pump shotgun (27 inch barrel). The magazine tube would originally only hold 2 shells, but now it holds 10. Very pleased with the product. Although it is blued and not matte black like my shotgun, that is not a problem. Still looks great. The pump action works great while chambering and ejecting all ten (+1) shells. The shell sizes I'm using range from 2 3\4 to 3 inch. Assembly was easy, and, in my case, did not have to make any alterations.
