Question: How well does this vise work with the AR15 ?
Document: Well made,  strong, and sturdy. Purchased to do heavy duty work on a heavy barrel rifle. Far surpasses the cheat Chinese, plastic stuff out there. More than a cleaning station, perfect for barrel in letting using hand and motor tools.American made, great job! !
Was debating on getting a couple different vises sold at BassPro. None of them impressed me. Plastic stands/vises to use on guns  where you need to manhandle things sometimes just don't seem to mix very well. This is a solidly made stand out of welded steel. You're not going to break this thing. It is also versatile. You can make a lot of adjustments to get your different guns settled in just right to work on.
The cleaning rod holder is made to work that way. ** the leveling screw blocks and vice tightening mechanism are made of some type of neoprene, or similar material. They can be easily cross threaded initially if not careful. Otherwise they seem to work quite well. ** Tools required for assembly will be a couple of wrenches and a phillips screw driver. ** All nuts (4) are self-locking. ** The vice assembly has a mind of its own.
If loosened to remove a firearm, don't try to pick up the entire T assembly by just the vice head as it may fall off. The vice is designed to work quite well when tightened but it remains very loose, even floppy, on the main rail if not tightened on itself when no firearm is present.After assembly, being anxious to see how it held a firearm, I clamped down the longest gun I have, a WW-II Mauser that is 48" long.
I am very impressed at how tight and stable the Mauser could be locked in the vice. There was no tendency for the gun to have the center of gravity forward of the front Y rest, and no tendency for the secured gun to rock forward with reasonable pressure on the barrel. This vice should work well for cleaning firearms and also for holding the gun steady for sight and scope installations.All things considered, I am VERY HAPPY and impressed with this purchase.
This piece of junk is just about the worst piece of equipment I now own. Go ahead and put your rifle in it and try and adjust it for your scope. It s a joke. I will not purchase a thing from CTK again. I even showed some friends how poor this vise was at the range club I belong to and they could not believe how junky and poorly made this CTK P3 Gun Vise is. I will use sand bags from now on. They may be archaic but they always work.
For years I've been using various gun rests to to do repairs, cleaning and scope mounting. One of the biggest problem is keeping a rifle or handgun level when mounting a scope, red dot,  to square off the reticle ( up,down,right,left ). This vise comes pretty close to keeping a firearm locked in place for this type of work. Once you get the firearm close to 0 level, you can use the two front leveling screws to level off your firearm.
As it is, you can work on the rifle in different positions by unclamping, rotating the rifle, and reclamping.
One of a kind and worth the money, Only one you will ever need, a work rest and shooting stand in one, all my bros want to use it.
I bought this for my fianc&eacute;e for his birthday, and he loves it!! Although it took some work to put together and the assembly instructions are horrible, it was worth it! Wonderful quality at a good price.
