With 14 strategically placed holes, 2 grooves and a larger design, precise pin alignment is made easy for all firearms. This block was constructed with upmost attention to detail for those looking to clean, repair or modify their firearms. The three elongated slots quickly align with compact size to full size pistols. Both the vertical and horizontal grooves offer the properly needed length and cutouts for work to be performed on long and short action bolts. To help secure parts, frames or barrels firmly in place, two Smart-Block Clamps have been incorporated into the block, allowing the end user to focus purely on the task at hand. Mounted inside are two strong magnets that grasp any pin you punch out and hold it securely to the block.
