308 AR LOWER RECEIVER VISE BLOCK Reviews & Ratings

308 AR LOWER RECEIVER VISE BLOCK

Heavy-duty vise block takes all the clamping force, so your expensive lower receiver won’t get scratched, distorted, or otherwise damaged. Insert block into the mag well, just like an ordinary magazine, then clamp the other end in your bench vise.

Obviously mismanufactured

On further review, it's obvious to me that their fixture slipped at some point and no one noticed that the whole thing is off by 10 degrees which pretty much negates its usefulness as a tool. I've seen better Jr High School shop projects. I wish I would've seen the Sincair tool for half the price before I bought this.

An unsatisfactory tool

For the price of this tool, you would think that they would've finished it. Out of the package it is not useable. The angles that are milled into it are off by at least 10 degrees, it won't lock into the receiver like a magazine does. The edges have to be cut off before it will even enter the mag well. This is no more than a kit, to be finished by the end user and as such it is worth no more than the base material, $10.00 at the most! Don't waste your money on this.

Does not fit out of the package.

This is being used on a DPMS G2 Recon 308. Let's start by saying that magazine wells don't have square corners, but this block does... All four corners needed to be chamfered AND additional machining was required to get it to fit properly. I understand the need for a tight fit, but the block was about 10 mil to large fore/aft to insert into the mag well. The tooling marks indicate that this piece was hogged out fast to minimize machine time. A slower travel rate and lighter cuts would reduce the deflection of the plastic/tooling and improve dimensional tolerancing. For the price, this is a poorly machined piece that suffers from poor quality control and improper geometry. Either drop the price or improve the quality.

Poor quality

The shoulder on the one I received, when resting flat in the jaws of the vice, does not put the rifle in a horizontal position. Instead the muzzle is pointed upwards and the entire block has to be re-positioned in the vise in order for the rifle to be parallel with the work surface. My AR15 block does not work this way. Additionally, the R-25 end of the block is too large to easily fit into the magazine well of my POF P-308. I'm going to try removing additional stock and knock down the sharp corners with a dremel tool so it might fit more easily. Way too expensive piece of plastic that was not machined correctly.
