[ARCHIVED THREAD] - Looking for lightweight 16" barrel, dissipator???

Posted: 9/14/2004 4:34:18 PM EDT

Hey guys, I've been out of the loop for a while. I want to build a super light AR. My lightweight M4gery has really turned into a heavy pig as the years have gone by ;) .

I see that Bushmaster has a Superlight 16" barrel. Tempting, but I'm interested in the longer sight radius of the Dissispator style barrels. Does anybody make a lightweight dissipator barrel? Anybody know the weight difference between the new Superlight and a Dissipator?

Thanks in advance,

Lukejt

Other than Bushmaster? I don't think so. You could always have someone cut down a 20" govt. profile barrel and open up the gas port.

I went ahead and ordered a Bushmaster Dissipator. I see that BM does lighten the thing under the handguards in the M4 profile. I want to use open sights on this gun, so the longer radius is a big plus. Looking to try out a CAV Arms lower for added weight savings.

I called BM today and asked them the difference between the two. They guy simply said "ounces, maybe half a pound.". That was not enough difference for me to switch. I've just been cautious about what I'm mounting to the thing. That's why the only things I haven't changed are the handguards and the front sight.

A 16" HBAR barrel weighs more than the M16A2 barrel and the Dissipator has an extra gas block under the handguards so it's even heavier.

I had a Dissipator turned down under the handguards several years ago and the weight savings and improvement in balance is significant.

On a scale lightweight Dissipator is 4.8oz heavier than the M4 barrel (all up including handguards, etc), and 8.7oz lighter than the M16A2 barrel. There's your "half pound." (M4 bbl is about 13oz lighter than the M16A2.)

The best thing to do is have a Gov't profile 20" barrel cut to 16" and have any gas port work done that's needed.

ETA: Actually, thinking more about it, is there enough material on an SP1 20" barrel to thread the new muzzle if it were to be cut down to 16"? If there is, then you can't get any lighter than that.
