Lothar Walther chambers our SPR AR15 barrels with .223 Wylde chambers which will fire 5.56X45 ammunition as well as .223 Match ammunition from Lapua, Federal, Winchester, Hornady and Fiocchi as well as any other SAMMI or C.I.P specification ammunition. The AR-15 SPR barrels are completely stress relieved after they have been rifled. They are machined on the highest quality CNC turning centers and checked for straightness both before and after turning. The Lothar Walther button rifled match grade barrels are CNC taper lapped by Lothar Walther after the chambers have been reamed. The LW-50 Polygonal stainless steel barrels have a ground external finish and are supplied with an M4 barrel extension and have been gas ported. The AR15 barrels we offer are necessary to complete your AR-15 upper assembly build or project. The barrels provide known accuracy with Sierra’s .224 diameter 69 grain Match Kings as well as the .224 diameter 77 Match Kings which are used by Federal, Winchester, and Fiocchi for loaded .223 Match and 5.56X45mm Nato Match ammunition. The 69 MK and 77 MK provide consistent accuracy for tactical and long range competitions.
