TexasArmor84 posted review of the Remington 870 Wilson Combat +2 Magazine Extension Review on Remington 870 Forum:
Finally installed a Wilson Combat +2 extension quick detach sling stud. My thoughts on this product is that it is very well made all steel very tuff. The kit came with mag extension, spring, wave washer(which you will need if you do not have a detent ball) and a high viz lime green follower which I didn’t install because I installed a Brownells SS follower. Also installed a Remington super cell butt pad fit was perfect and a ProMag Archangel 7 round shell holder. All said cycled dummy rounds and function is smooth and no FTF what’s so ever. This project started off with a simple Remington 870 Home Defense 4+1 model and thanks to Rem870.com forum I was able to transform my 870. Also thanks to Vitaly for the site that made this happen now the field test is to come soon.
