HS-Armory Pre-Embeded Laps - 3pk

$10.00

These are the new pre-embedded versions of the HS-Armory lapping system which make it easier than ever to increase accuracy via barrel lapping. They come with the abrasive already embedded into the lap and just need to be pushed through your barrel with a standard cleaning rod. They use a single CrOX abrasive so while they won't cut as fast or as deep as the coarser abrasives in the higher level kits they can easily be driven through your barrel as many times as you would like.

These are generally pretty simple to use, just insert them into the muzzle end of your barrel and push to the end with either the flat or cleaning end (not the unjamming end) of your cleaning rod. If you are using the a standard lapping drive rod (like the brass ones also available) see the lapping manual here for push-pull instructions. Just repeat this rotating the lap's angle each time until you are satisfied with the surface finish. Clean the barrel with a solvent after lapping and apply a lubricant (like a light silicone oil) if you like making sure to use a dry wipe to remove most of the lubricant after.

The latest development in pushing the limits of accuracy from HunterSeeker5 has arrived, the barrel lapping system. Some of you may have heard or even tried barrel polishing in the past and noticed it offers some advantage. Well polishing and lapping are not the same process. Where simple polishing removes micro scratches from the surface and improves surface finish it does not make any attempt at leveling the surface. Lapping uses abrasive embedded plates to file down high spots and level the surface while still leaving a mirror finish. This smoother surface on both the micro and macro level allows BBs to glide along the barrel with minimal disturbance and off axis spin. This system works great on both cheap stock barrels and high end Japanese barrels, while high end barrels have much better than stock tolerances they are still far from the surface you get from lapping. These shouldn't be used on coated barrels as they will remove the coating so brass and stainless are fine while most aluminum aren't. These are the 8th gen version of the lapps that have single large area sections in a spiral pattern. They provide better leveling than previous versions and the spiral pattern allows them to cut more evenly around the circumference.
