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. The magazine catch locks to the block, safely and securely holding the rifle for assembly, disassembly, cleaning, or repair. Double-ended design fits ArmaLite® AR-10®, Bushmaster .308, DPMS Panther™ LR-308, and Remington R-25. Does not fit Rock River Arms lower receivers. Machined from rugged, durable, chemical-resistant Delrin® polymer; will not mar or scratch weapon’s finish.

Value for Money

38%

The pricing of the vise block is cited as an area of concern, with multiple reviewers feeling that its quality does not justify the cost.

Worked perfectly in My Aero Precision

Did my first build. Worked perfectly in my Aero Lower. I have not yet tried it in my SR25 or Noreen Lowers. No issues at all holding securely for barrel installation.

Works as advertised

Fits my M&P 10 perfectly. Nice solid hold while cleaning or working on my rifle.

Yes, you have to fit it.

This is a gunsmith tool, and as such it didn't surprise me that it required a little bit of fitting. I wouldn't have it any other way, because I got a nice tight fit on my DPMS Recon. Guys who are sanding and dremel-ing on nylon are doing way too much work. It only took a couple of passes with a sharp knife to break the corner on only two of the edges of this block. Now my rifle sits over the vise and does not move. Excellent.

Works Great

I just got this block and it works great in both my AR-10 mag well and my R-25/LR308 mag well. Does exactly what it's supposed to.

Will not fit a S&W M&P10 .308

This is a very nice product but will not fit the highly proprietary S&W M&P10. I thought it would work since the DPMS mags fit the M&P10 without issue. The block is just slightly too large on the DPMS side and will not enter the well more than one inch before jamming. I intend to keep it as it is the closest match that I have found to date, and it appears that a little sandpaper work will achieve a fit.

Great product, awful price

The block itself is solid and exactly what you would expect in a lower receiver vise block. It fits perfectly with my DPMS lower. The block itself earns 5 stars, when you don't consider the cost.

Not a good fit

Nice quality but found out that it DOES NOT fit a SIG716 magwell...its to big or the Sig is to small.May work on other AR-10 style rifles.

.308 Lower Receiver Block

I purchased the Lower Receiver Block to work on a KAC SR25 and it was way too tight for the magwell, would only go in 1/3 the way. Worked on a Larue rifle, but not on the KAC, so I had to return it. As usual, Brownells exceptional customer service was on the money and refunded my account.....even though the block did not fit, I am very pleased with the CS...that is why I am a loyal customer

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.
