The design is a good concept, install is easy with no special tools required (no buffer tube nut wrench needed) Just remember to follow instructions and DO NOT OVERTIGHTEN, you can distort your buffer tube and gun will not function. Remember, tight is tight enough and if ring does not come completely together, that's ok, the sling mount will not move, its tight enough. The screws have some material on them to prevent them from backing out. Overall it works ok and Ill keep it.
I bought this three days ago and just got. I was already pretty jacked about it and could hardly wait. Once I got it and put it on, I was even more impressed. Fits great, very solid/tough and looks great. I have a M&P 15 and it fit it perfectly. It mounts with for screws, rather than the usual standard of one, which gave me even more confidence of its toughness and reliability. Its build is solid and once mounted, it is not going anywhere. Great product, worth every dollar and you will be very happy. The swivel it comes with can be positioned in the 3, 6 and 9 o'clock position. This versatility option is great. Very impressed!
WELL MADE PRODUCT, ONLY HAD TO PUT IT ON DIFFERENT AR THAN WANTED TO, DUE TO BEING MADE FOR MIL-SPEC TUBE ONLY. DOES NOT FIT COMMERICAL TUBES WHICH ARE NOT MACHINED COMPLETLY ROUND NEAR THE RECEIVER THREADED END, SO IT WILL NOT MATE UP RIGHT AND SEAT AS WELL. FYI FOR ALL THAT MAY HAVE A COMMERICAL BUFFER TUBE. GREAT PRODUCT, BUT ALSO BOUGHT A TROY BUFFER TUBE MOUNT WHICH WILL FIT BOTH TUBES DUE TO THE WAY IN MOUNTS OVER THE CASTLE NUT.
