I recently purchased a RRA 15" M4 style chrome-lined barrel and am wondering if I should sell it and purchase a Bushmaster M4 style 14.5" barrel instead (I don't have a lower yet upon which to mount it to test fire it). Because this is a limited production barrel, there don't seem to be many reviews regarding the performance/accuracy of the barrel.
I just don't know how good of a barrel it is.
Which of these two barrels is better?
What would you do?
Thanks for your help.
The difference is so small, it probably can't be seen.
1/2" - the velocity difference would be so small that it would be unnoticable at this barrel length
4150 steel vs. 4140 steel - no difference to 99.99999999% of the users
Both need permanently attached muzzle devices, unless you go the SBR route
I'd not change for the sake of change. I'd have had the Bushmaster barrel in the first place, anyway. YMMV.
I would personally prefer the Bushy bbl but if you already have the RRA bbl it's not worth it to change.
