The Block-Worx two
piece holding fixture for the AR-15 family of flat-top upper receivers
offers superior protection for your AR-15 upper receiver while
performing a number of maintence and assembly functions.
This
set can be used with left or right hand uppers, 9MM or rim-fire uppers,
most any variant of the AR-15 family of flat-top upper receivers will
work 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 upper
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… ETC.
Basically any operation that does not
require a great amount of torque can be performed by using either the
top portion or bottom portion by themselves.
And
unlike other action blocks the Block-Worx holding fixture set does
not require removal of the bolt and charging handle in order to clamp
the receiver and because of this the Block-Worx 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.
