This is the only good solution I have found to run on my mtw with the wraith to keep the stock/bottle from spinning when attaching a sling. It’s a better setup than the wolverine clamping stock or a stock bar that mounts to the bottle because that would have the same rotation issue. Only 4 star because while I assume there is a reason in polarstar builds for the whole behind the stock bar if it was dimpled like a ar receiver endplate it could not rotate. I wished they included an adapter to put in that hole for that reason as this can still rotate. I believe if I get the ar receiver end plate that will completely solve my issue. Other than that this is a very nice quality part and I do like its design for the most part other than I can’t get my armors wrench on the castle nut because it recesses into the endplate too much. Nothing a punch and hammer won’t fix I would just prefer to use the tool made specifically for the purpose.
