The Barrel Extension Vise is an all-in-one, compact vise block for the AR-15/M4. Takes the worry out of applying torque to your upper when installing and removing barrel nuts and muzzle devices by engaging the barrel extension with solid steel lugs and a full-length support shank to prevent flexing. This prevents torque from being transferred to the softer aluminum receiver.

Features:
  • Provides support for all AR-15/M4 upper and lower receivers
  • Solidly engages barrel extension with steel lugs
  • Full-length steel support shank
  • Body made from the same high-quality polymer as other Magpul products
  • Weight: 11.2 oz
Mounts securely in a vise and provides support for both billet and forged upper receivers. Steel hardness is optimized for durability yet won't damage barrel extension, and Magpul Polymer is used for all other engagement surfaces to protect the aluminum receiver. An O-ring post uses the bolt carrier for additional stability and an included pin keeps the upper receiver in proper position. The BEV may also be turned over and used as a mag well vise block to support the lower receiver during maintenance, etc.

Magpul continues to grow and develop based on innovation, simplicity, and efficiency. At Magpul, mission driven requirements inform their product design, materials, and manufacturing, focusing on efficiency without sacrificing quality or performance.

Good With Comments Not So Good

I've used the clamshells, which I don't like, and I've used the "bar" type that uses pins through the receiver coupling pin holes, and I do like them. I was attracted to the BEV as it locks up on the barrel extension like a reaction rod. It does do that but it is a sloppy, wobbly fit even with a stripped bolt carrier engaged from the rear. It does what it is intended to, swapping barrels and muzzle devices with all the torque isolated from the upper, but I will continue to use the bar type for light maintenance. It's more solid. Please don't misread this. It does isolate the torque from the upper as intended.

2 Tools in 1 & Magpul quality

I used this to install a new stock kit on my DPMS today and it did everything it was meant to do. I DISAGREE with the reviewer that said it didn't lock in the magwell. My mag catch locked into the block and kept things where they needed to be & stayed until I pressed the mag release. Tried the barrel spines on a spare barrel and while it IS a little loose it should isolate the torque from the upper receiver when removing or installing a muzzle device or barrel nut just fine. I highly recommend this tool to anyone that likes a combo tool.

Outstanding! Now Where's the LR308 BEV BLOCK?

I absolutely LOVE this thing! I actually have two so I can put two lowers in the vice at once just to show off your dope assembly gear... PLEASE PRIMARY ask Magpul to Make a LR308 Version!!!! I would buy two of those also! And yes, I do strip the carrier and lock it into position with the pins when i torque or remove barrel nuts and muzzle devices! And I have put TON of pressure on this thing loosening stubborn barrel nuts and it just takes it time after time. I love Magpul; its just good stuff at a reasonable price. I don't have any complaints about my bevBlock other than I don't have one for 308. My Geissele AR10 reaction rod cost a small fortune!

Great block!

Like how this engaged the barrel itself rather than encasing the upper. Used on both my 6.8 & 5.56. It was slightly loose on my 6.8 barrel but still did a good job. I tried locking it into my upper using the plastic pivot pins provided but they were a pain to put in & take back out. Maybe sanding the detents on the pins down a little would help but i got the job done without locking it into my upper.

Best tool on market

If your going to tear down, build or rebuild this tool is a god send...made my repairs so easy and much less frustrating. Much safer and less risk of damaging components. This with a bench block and your set !

Product was just what I needed. Worked as upper and lower receiver vise. Very happy with product and with Primary Arms on time delivery.

Saved my barrel and upper receiver

by

I was doing my first build and used this device. I had no idea what 30-50 ft lbs of torque felt like (it’s not that much) and my torque wrench failed to click because I had it in a backwards configuration (go ahead and laugh, I was a noob).

Anyways, this resulted in me putting OVER 100 FT LBS of torque on my barrel nut. Should’ve been enough to destroy the receiver, the barrel, and the barrel extension. Turns out that even though the aluminum barrel nut cracked and its wrench indexing teeth sheared partially off, the receiver and barrel were perfectly unscathed and were cleared by both the manufacturers and a gunsmith as being in great condition.

Anyway. Long story short, if it weren’t for the BEV block being inserted in the barrel lugs, my receiver and barrel would’ve been destroyed. Instead, they’re in perfect condition and I’m a little wiser and very grateful for this product
