Works maybe, but is definitely way too expensive - Magpul SGA Remington 870 Reciever Sling Mount MAG507

This is typical Magpul product, lots of hype and it generally works OK, but it is expensive, much more than it should be. Magpul imho does this all the time, they create a product like a rifle stock, charge you a high price, then nickel dime you to death to buy options that should have come with the original product! It reminds me of Microsoft..suck you in then charge you for every single separate piece and support! While I think many of their products work fine(AR mags) many of their products are over priced and other manuf. give you similar options that work as well with equal quality at a better value. this set up with many individuals who do not go in harms way has limited use. Shotgun slings are generally best used to transport the firearm from A to B, they are not as effective in a tactical environment and many professionals advocate that they are not used in CQB, because they can be grabbed etc by an adversary easily! In addition, look at the set up with the swivel/attachments on the same side as the ubiquitous arm chair commando hard side saddle...ever try and put that firearm on your back or close too you? try it...not much fun and no comfort at all! Put the mounts on the other side..where it is FLAT and will also prevent the firearm from "rolling" better.
