Description:

Protect Receiver From Damage When Clamping
Heavy-duty blocks allow you to firmly clamp AR-15/M16 receiver halves in a vise without risk of crushing, twisting, or otherwise distorting them when applying vise pressure or torquing the barrel nut. Keeps your rifle secure for safe, effective cleaning, assembly, and repair. High pressure, solvent resistant, structural Rynite block and insert surround the entire upper receiver and support it inside and out to make rebarreling the AR-15/M16 an easy, one-man job. Lets you firmly secure a mil-spec carry handle receiver or mil-spec flattop receiver in a large bench vise for barrel removal/installation. Torque generated while tightening the barrel nut is transmitted to the block and insert, not the receiver. Minimizes the possibility of damage to the barrel detent pin and receiver detent notch. Holds securely without marring the finish.  DO NOT USE ON BILLET UPPERS OR LEFT HAND UPPERS, OR DAMAGE TO THE UPPER CAN RESULT.

Definitely recommended

Brownells USA Works just like it should have 05/04/2011

I had a Spike's Tactical upper and it worked just like it was supposed to. The insert that goes inside the receiver was loose the whole time however. I'm not sure if it was doing anything. I ended up having to put 70 foot pounds of torque on the barrel nut to index the next hole and it worked flawlessly.

Brownells USA Maybe being picky 27/01/2011

Great looking block, fits a carry handle and a flatty I have perfect, however I would have liked to have seen the insert fit tighter inside the upper. Maybe I'm too picky but it seems like it would be better if it was more of a slip fit than a loose fit.

Seems really stout though and it's good the hinge has a little preload to it, should help hold the receiver in and not drop it on the floor while you are placing in your vise
