Specification Brand : PLASMAGAL BulletPoint1 : Twenty 1/2 × 28 stainless‑steel shims in five calibrated thicknesses (0.004‑0.040″) let you clock muzzle brakes, flash hiders or suppressor mounts on .223 / 5.56 mm sporting barrels with fingertip torque, eliminating crushed washers, over‑tightening and repeated trial‑and‑error sessions at the bench. BulletPoint2 : Use a single 0.004″ shim for micro corrections or stack several layers to raise a free‑float barrel nut in precise 0.10 mm steps, aligning gas‑tube ports perfectly, protecting thread shoulders from 90 – 100 ft‑lb torque and achieving repeatable concentricity shot after shot. BulletPoint3 : Each shim is CNC‑machined, deburred and glass‑bead finished to resist corrosion, galling and heat discoloration; they can be removed, cleaned and re‑installed indefinitely, saving money versus disposable crush washers and guaranteeing consistent muzzle timing on every rebuild. BulletPoint4 : Every thickness ships in its own colour‑coded bag with ink‑stamped dimension so you identify the right piece instantly, cut set‑up time in half and keep spare shims organised in the workshop, range bag or armourer’s roll without having to measure with calipers each time. BulletPoint5 : Beyond muzzle devices, these precision shims true scope rails, space Picatinny risers, correct suppressor end‑caps, level sizing dies or shim shell holders during case‑reloading, making this 20‑piece kit an essential accessory for builders, competitors and enthusiasts who demand sub‑MOA alignment.
