Quoted: Are these barrels inherently any less accurate on the first few shots, or does the accuracy only degrade under rapid fire?
|
When cold my superlight is just as accurate as any other Bushy barrel. I have not done accuracy testing with the barrel when hot. I can tell you it WILL keep all the rounds in a 2"x4" box at 50 yards when has been exercised and it too hot to touch.
In other words, is there really *any* point to having excess steel on your barrel when the accuracy potential is limited by the chrome lining process?
|
Not IMHO. If you're really looking for that supream accuracy you should be looking for a stainless barrel, or a quality chrome-moly.
Would this barrel be permanently damaged by dumping a beta mag or two through it as fast as possible?
|
Uhh no - this was the same barrel profile that was used for 20+ years the M16A1 and XM177 series. Though I caution you about doing two beta dumps - that would exceed the cookoff danger point (just as it would if you did the same 200 rounds through a M4 or M16A2 barrel). I don't know if the HBAR has the same cookoff point.
Is it possible to order the barrel without the drilled holes for the front sight taper pins?
|
No.
Can this barrel be had with the M4 extension, or will I have to have that added on afterwards?
|
Not from Bushmaster, you'd have to order it from Colt to get the M4 feedramps.
Also I seriously doubt you could add an M4 extension to an existing barrel - the extensions are timed to the barrel and the gas port is drilled based on the extension. Near impossible to retrofit a new extension. Your only hope with the Bushmaster would be to dremel the ramps in.
Though I've never had a need for them in the last 2 years and thousands and thousands of rounds of ammo of all types (from Wolf to Black Hills 75gr OTM).
Does anyone else make a barrel that compares to the Bushmaster superlight?

Colt. (and expect to pay twice as much)
If price is no object as you say, then call up SAW Sales and order the Colt barrel.
