Honestly all you need is a vise and some soft jaw pads (or wood) to clamp on the barrel at a 45 dgree angle in the vise with the barrel and part of the front sight assemblly in the jaws so the barrel will not spin. Do not clamp on the reveiver without a proper receiver block.
Then take the flash hider off. Standard Flash Hider will take a 3/4" open end wrench. Some breaks take a 13/16" wrench. Then take out the Front Sight Taper Pins from the Front Sight on the Barre;. Since you have a S&W the Taper Pins will remove *Right to Left which is the opposite as the mil spec specification. Smith as well as Stag messed the normal procedure up. On most rifles and Mil Spec they are installed Right to Left and removed Left to Right but as previously stated yours should remove Right to Left. You can see it by noticing the Taper Pin Heads are larger on one side than then other. You can also use a wood block with a hole drilled in it to support the barrel while removing the taper pins. Once you remove the flash hider, front sight assembly and gas tube from the upper. You can take a Dremmel Tool with a small round metal cutting blade and cut the Delta Ring through on one side then rotate 180 degrees and cut it through on the other side. It will break apart for removal at that point. Then take a large screwdriver and spread the Weld Spring apart until you can get it off. The Snap Ring can then be forced off of the original Barrel Nut which will need to remain on the barrel. Then Troy Alpha is now ready for installation.
Good luck and there are plenty here who can help should you have any questions.
