so i am building a new carbine and i have it in my head that bushmaster makes the best barrels for the buck. i am not quyestioning bushy but was wondering if this is true? how so they compare to saber, RRA, stag, and CMMG?

Its been awhile since I've bought a Bushie barrel, but the ones I've used have done quite well for me.


Saber, CMMG, and Stag/ CMT all make pretty decent barrels as well, but I think the Saber and CMMG will run quite a bit more.



We are talking about chrome lined barrels right......?

Bushmaster makes a good barrel for the money, if a 1/9 twist is ok with you. i have three BFI barrels in total. one of them has about 12k rounds through it, mostly Wolf, and its still grouping fine (as one would expect).

BFI barrels are quite good, they use better steel in their bbls than some of the other well known brands, chrome lining is standard....as long as you aren't planning on using the heavier bullet types, it should serve you just fine.

Bushmaster makes great barrels. I just wish they made more 1:7" twist barrels.

I've never had a problem with the BM CL barrels. While they do make occasional runs of 1/7 barrels, the vast majority are 1/9. Most of my shooting is done with 55 gr so the 1/9 works fine.

so if i wanna shoot a heavier grain than 55gr 1/7 twist would be recomended?

A 1:9" twist can handle anything up to 69 Gr. Some 1:9" barrels can actually handle 75/77 Gr. bullets. Ideally, the 1:8" twist barrel would be great, but there aren't many chrome lined 1:8" twist barrels around except for the CMMG 18".

The 1:7" will handle anything from 45-80+ Gr.

yes. i've heard that the stainless Rainier barrels are nice, but never run them myself.


comparing an ultra-match stainless Shilen blank bbl from Rainier to a CL Bushie bbl isn't really fair tho. two totally different classes of equipment.

what if i wanna get a .22LR kit and shoot .22LR as well? would a 1/7 be fine and would the .22LR have any problems?

If you are looking at doing much with a .22 subcal kit, the 1/9 would probably be a better way to go. If you are looking at shooting a lot of .22, and for accuracy, you would want to get a different barrel or dedicated upper.

so i will prolly be mainly shoot 55gr and 62 gr. will a 1/9 over 1/7 be that much of a difference? anything significant?

1:9 or 1:7 will handle 193 and 855 all day.

Any of the high end barrels will likely outperform its shooter in the accuracy department - GTS/Rainier/WOA/RRA/Sabre/CMMG/Noveske/Lothar/Douglas/Kreiger /etc.

For just practical shooting, anything will do. Chrome lining you'll want, M4 ramp cuts in the upper are nice to have, but if you're not running the poo out of that upper, the more affordably priced STAGs will do just fine.

For a .22lr/.223 setup - I'd go with a STAG or Bushy 1:9 barrel (cheap, work), and CMMG conversion kit. Won't need a hugely expensive barrel, but it will get the job done at a good price. CMMG carries 1:7 as well as 1:12 as options - but a 1:9 will handle everything from lr to 69grSMK's.
