Does anyone know if the bushmaster lightweight chrome lined barrels are any good. Have been thinking about building a lightweight but did not know if I should just buy one of the cmmg lightweight uppers. Just trying to gauge quality before I do anything. I have never had a bushmaster barrel. Thanks, RG

I have used Bushmaster barrels on 4 builds. Top notch.

If you're a nitpicker, you should know that 3 out of 4 had little dings in the finish when I got them. Someone at the BM shipping dept. apparently likes to knock over stacks of barrels. Yours may very well be perfect. They are well-made and accurate.

I'm in the process of finishing up my first build. I decided to go with a Bushmasters super lightweight barrel also. Everything I heard and read was positive. I can IM you with a range report after I get it finished.

Have a 1/7 Superlight I'm very happy with. Only wish it was a 14.5!

I have a Bushmaster upper with their 1/9 super lightweight barrel. When I was looking I had trouble deciding between the M4 and superlight barrel - I am very happy I went with the superlight and would buy again in a heart beat.

All I have is a BM 14.5" M4 barrel on my duty rifle. It's 1/7 Chrome Lined 5.56mm. It does what I need it to do with no chamber/gas system issues.

I got on a month ago.
They are chrome-lined. (the DPMS lightweights are not. i have owned 2)
I have no problems with grouping as the barrel gets hot. i have not gotten it white hot, but too hot to handle nontheless.

I have a 16" superlight and I love it and would buy another.

I have a 1-9" superlite and it is a good barrel. It will hold to 3"-4" groups at 100 with a 4x scope, just on it for a accuracy test iron sights are normal. If you have some accuracy requirements this is not the way to go, if you want a light weight carbine that you can carry all day they are the way to fly.

Just received mine in the mail yesterday! So far so good! Finish was flawless and everything went together perfect. I love the feel of the rifle. Can't wait to get it to the range.

i found that the weight difference in the ultralight and m4style barrells is not that significant give the rest of the rifle. i stick to m4 barrells now.


My experiences with the superlight is identical... less than 1/2 pound lighter than an M4 profile and MUCH more "whippy" (groups opening up).

Additionally most superlight barrels I've seen use the smaller diameter FSB, so standard GB and FSB's (.750") can't be used if you want to change at a later date.

+1

Built one for my 10 year old son w/one, and both of us love it.

One note on both the barrel mentioned, and the M4 14.5 incher on my M4gery.

Both of them were apparently measured for length to the end of the chamber, NOT from the front to the face of the bolt, which is the standard way to measure barrel length. This makes them actually about 1/4 inch longer than advertised. That worked out well for me when making the M4 barrel a legal 16 inches; because using a crush washer and a thicker than normal A1 type split washer,and permanently attaching a standard A2 flash suppressor gave me a 16.1 inch legal barrel; and saved me having to buy one of the grossly overpriced extended flash suppressors.

I'd be interested to hear from some of the other Bushie carbine barrel owners, both 14.5 and 16 inch prople as to the actual length of their barrels from muzzle to bolt face.
