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.

US
incredible receiver block
holds the upper securely, no wobble at all. the pins are loose, but the upper is held securely to the receiver block without them. probably absorbs some of the force from using a wrench, so i'll keep them in anyway, just my guess. in the background on my table you can see two other brands' receiver blocks i am unhappy with. no longer do i feel like i'm going to bend my receiver or something similarly catastrophic. great product.
USMade installation of my muzzle device a breeze
Very easy to put on my upper receiver and attach to my vice. This is a great budget friendly alternative to “the device”.
USGood to go.
Work's as designed. Nice tight fit. I like the way it comes apart and that it can be used as a cleaning jig. Way more secure than the clamp style holders.
USGotta 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.
