Awesome accessory This product was installed on my Mossberg 500A(shotgun was purchased at Big 5). I mounted a red dot scope to my gun. November 11, 2014
great quality product! I was a bit hesitant about buying this product because it was so economically priced. Luckily this is a fantastic item! It lined up perfectly with my mossbergs predrilled holes an I had it mounted in a minute. Then the tru glo scope I purchased at dicks mounted right up perfect. Great item at a great price!!!

Just what I needed After looking for this part for my Mossberg 835 Ulti-Mag at several reputable gun shops across town, I was surprised to find it at dicks. Quality piece, easy to install, used it to mount a red dot for turkey season. February 20, 2013
Just a good buy This is just a good rail that you can slap on your gun. I liked the price and it was easy enough to install. I would recommend this product over others because its not complicated or expensive and works with several gun models. January 29, 2013
Aluminum Base by Weaver WORKS PERFECT,QUALITY PRODUCT August 24, 2012
Just what I needed Fit my mossberg 835 just right. Watch out Turkey May 15, 2012
Weaver Scope Base Product is simple to install and fits perfect, screws were included and with a dab of LocTite it was installed in seconds. I used this base on a camo Mossberg 500 20 gauge along with a Bushnell red-dot scope to get ready for this years Spring Turkey Season. We shot several rounds to get the scope sighted in and the 417 base did it's job by staying rock solid and right where it belongs. Weaver has been making Great products for a long, Long time and they continue to produce the same quality today. April 23, 2012
went right on Worked great. Install easy taking the old screws out of the mossburg was difficult. It will look great with a read dot or a rear sight. April 16, 2012
