GrovTec USA .223/5.56 Alignment Rod Features The GrovTec USA .223/5.56 Alignment Rod is machined from ground O1 tool steel a material chosen for its hardness and dimensional stability so the rod holds a true consistent diameter through repeated use. At 15 inches overall the rod is long enough to pass through the bore and into the suppressor cavity confirming that the two components line up concentrically before the suppressor is torqued down. Verifying alignment this way helps prevent baffle strikes a common cause of suppressor damage when a barrel and can are not perfectly matched. This rod is sized specifically for .223 and 5.56mm bores matching the exact dimensions those barrels require for an accurate check. A black oxide finish coats the tool steel to resist corrosion and reduce friction as the rod slides into the barrel and suppressor. The straightforward design requires no batteries or special tools just a steady hand to insert the rod and visually confirm alignment. GrovTec builds its accessories in the USA backing the Alignment Rod with the same attention to ruggedness and reliability the company applies across its firearms accessory line. For anyone mounting a suppressor on a .223 or 5.56 rifle this rod is a simple dependable way to check the fit before firing available for sale at GrabAGun.
