Due to local laws, I HAVE to have a permanently fixed muzzle device regardless of barrel length. Taking that into consideration, I decided it made more sense to have the shorter 14.5" barrel with the 1.5" muzzle device pinned and welded. I also opted for Noveske's Light Weight Mid-length and it has been exceptionally reliable and accurate with .223/5.56 using just a standard Colt H carbine buffer. I contemplated the A5 system at one time, but after researching it here, it seemed like "too much of a good thing" as some have put it.
