Upper Receiver Block - Action block - Block Worx

The best, the original Block-Worx… “Patent Pending”

Please look at the feedback for this block set… it’s truly the best on the market!

Other upper receiver vice blocks can actually damage your upper, solving the problem of having uppers actually bend and crack when attempting to remove / install barrels was the inspiration for this block design. Unlike other popular receiver blocks, the Block-Worx set does not exert force on the weakest point of the upper receiver when working in the upper end of the torque range.

The Block-Worx two piece holding fixture for the "flat-top" family of upper receivers offers superior protection while performing a number of maintenance and assembly functions.

This set can be used with standard and non-standard uppers, billet uppers like the Vltor line, left or right hand uppers, Pistol caliber or rim-fire uppers, most any variant of the "flat-top" family of upper receivers can be safely secured in a vice with this set of action blocks and it will accommodate most hand guard configurations without modification to the fixture.

The two piece holding fixture provides the proper clamping position for barrel installation with no danger of warping or bending the receiver even at the upper end of the torque range. The bottom portion of the set can be used by itself for a number of operations such as scope installation, cleaning, bolt work, hand guard installation… ECT. Basically any operation that does not require a great amount of torque can be preformed by using either the top portion or bottom portion by themselves. And unlike other action blocks the Block-Works holding fixture set does not require removal of the bolt in order to clamp the receiver and because of this the Block-Works fixture also allows full access to the interior of the receiver for convenient cleaning of the receiver, barrel extension and bore from the breech rather than from the muzzle.
The Block-Worx holding fixture set is made from non-marring high density polymer and will provide years of service for less cost than most single piece action blocks.
