NcSTAR Upper Receiver Block for AR15 VTARUVB


Upper receiver block is designed to fits AR15/M4 receivers to help with assembly and general maintenance of AR receivers.

  • The modular AR15/M4 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 AR15/M4 upper receiver block fully supports the upper receiver to prevent damage from torque twisting forces when installing or removing barrels from the receiver.
  • The AR15/M4 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.

Very sturdy & nice looking! Impressive & functional
Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
I needed to divide our living room room in half and create a work room but didn’t want it to be visible so we decided to get this and use it in an L shape. It’s very simple and functional, but it does exactly what I need. I’m contemplating hanging a photograph from a ribbon just to add a little personality to the side that faces the living room room but honestly, it’s much more sturdy than I gave a credit for. I am a full-time reseller so I got foam from the hardware store and covered it in fabric as a background for taking pictures and I have a huge one that’s 6‘ x 3‘ plus another one that’s 4‘ x 4‘ both of which are hanging on the inside of this and it works great. I’m impressed!!

Weigh your options
Color: Grey, Size: 2 Large Panels
It serves the purpose but make sure you stabilize it. It's not a bad product it's extremely light and insecure without something to hold the base in place. Maybe it was just the one I bought but it moved a lotI would just bump it a little and it would fall over. The good thing is It is easy to set up and has versatile usage. Also it's really big. Takes up a lot of space make sure you measure your room first.

Functional not durable
Color: Grey, Size: 1 Large Panel
When first assembled, it looked exactly like the picture. However, over time, the top bar has begun to bow. The metal bars are weaker than I expected. It is still doing it's job providing privacy but the quality is not quite up to par. The height, color, and functionality are all exactly as described. If you need an inexpensive room divider, this is a great option. I don't expect it to last more than a year or two, but I would still recommend this product for those needing something fast, easy to assemble, and don't need for an extended period of time.

Good Product
Size: 3 Panel-102'', Color: Beige
I got these dividers for outdoor use for some privacy from neighbors. They arrived quickly and were easy to set up. They look good, and though the legs don’t offer stability against any amount of wind—which I expected as it wasn’t advertised for outdoor use—all it took was placing a cinder block on the feet to hold it up right. Coverage is good, it’s easy to fold and move as needed, and it’s light weight. All in all a decent product. I will caution the purchase of “used like-new,” as both of the dividers I ordered were previously returned items, and one came missing a cap, instructions were not included, and the poles were all mixed up and not properly labeled. If I had not ordered a second divider (which did include the instructions) I would have had a much harder time figuring out which pieces were which and how to put them together.
