Vism Upper receiver block is designed to fits AR15/M4 receivers to help with assembly and general maintenance of AR receivers.
Features:
-
- The modular upper receiver block can be used in several ways for many different maintenance tasks
- You may use just the lower half of the block by attaching it quickly to the upper receiver with the two provided receiver pins
- This allows you to clamp the AR upper receiver to a vise for maintenance work
- Bolting the two halves of the upper receiver block fully supports the upper receiver to prevent damage from torque twisting forces when installing or removing barrels from the receiver
- The upper half of the block inserts into the receiver just like a bolt carrier group
- The bottom half of the block can be bolted together with the upper half with the provided steel bolts
- This fully supports the inside and the bottom of the receiver and it also leaves the receiver optics rail open for mounting accessories and optics
- Unlike other upper receiver blocks that bolt/clamp to the exterior of the AR receiver
- The upper receiver block also has a hole through the length of the block to act as a bore brush guide for cleaning out the bore of the barrel
Constructed with blue anodized Aluminum.

Gotta have
This is a definite must have if you build on a regular basis. Great quality and snug fit. If this one ever wears out I will definitely get another one. Definitely will recommend to my friends.
United StatesVery solid tool
I have built quite a few AR's and have found this to be a very handy addition. The plastic vise blocks fail, and I even made my own hard wood jig for securing slick side uppers. This tool provides a solid work platform for irregular shaped and billet uppers, and mil-spec by securing the upper from the BCG channel. It takes a few minutes to assemble properly, but is worth the time to get everything secure and when placed in the vise it makes a solid work platform. Excellent for scope mounting and basic work. For securing a barrel, I do still prefer using a barrel extension torque tool to eleminate stress on the upper. Vism is usually budget gear, but this one was a good option.
United StatesJim 1- BCM 0
If anyone on here has ever attempted to take off a BCM barrel nut you know it's a insurmountable task this defeated it ,this is my new favorite upper receiver vice. Held it rock solid so I could use enough torque to remove barrel nut. BCM must use a machine loading over a 100 ft/lbs its ridiculous. Not to mention cosmic loctite they use. Phenomenal guns but man tough to disassemble.

My new favorite upper receiver tool!
Bought this on a bit of a whim, but also for a billet upper that I was going to assemble soon, since a standard "clamshell" type upper vise block won't work. Instead I think I've found my new favorite upper receiver vise block. It'll work on standard forged receivers also and won't mar the anodizing! Thanks AR15Discounts!
