Can I shoot 5.56mm out of a .223 Wylde Chamber?
I'm looking at this barrel:
Description:
We wanted to build an AR15 barrel using the finest blank and mass producing them to bring them to you at the most competitive price. Our ultra match barrels start out as Shilen blanks and contoured to our specifications. We wanted the best balance between accuracy while keeping the weight down as much as possible. It also features Shilen’s Ratchet Rifling™ which allows for better bullet travel through wind and easier cleaning.
Features:
■Stainless Steel Match Grade Shilen Blank
■Length: 10.5″
■Twist: 1:8
■.223 Wylde Chamber
■Carbine Gas System
■Ratchet Rifling™
■M4 Feed Ramps
■WOA Contour
■Bead Blasted Finish
But I also want to be able to shoot issued M855 rounds out of it. Please educate me on what the hell a .223 Wylde Chamber is.
