The Geissele Reaction Block is designed to aid in the assembly of lower receivers. Once the armorer has installed the buffer tube, the lower receiver can then be slid into the Reaction Block at the 12, 3, 6 and 9 o’clock positions. Allowing the armorer to rotate the lower in 90° incraments in the block simply by loosening the provided nylon screws, removing the lower and sliding it back in at its desired orientation. The Reaction Block provides an ultra-stable platform for performing an array of lower receiver operations, as well as making the installation of the buffer retainer nut quick and easy. All while keeping both hands of the armorer free to work, saving both time and frustration.

I have sever rifles and perform repairs and upgrades. Wedging the magwell into a cloth covered vice got old. This block is just the ticket. My first usage had me forget about the price. Having the proper tools is a must!
