Looking for bull barrel accuracy in a lightweight package?
Check out the new generation of barrels…carbon fiber, baby!
We cover the most popular ones in Best Carbon Fiber Barrels…but today we focus on BSF which brings us perforated carbon fiber instead of a wrap.
Plus…compared to the others out there…the BSF is the most affordable (I use that term loosely).
I only heard about BSF in the last year but they are making a splash in the carbon fiber (CF) arena with their perforated barrels instead of standard wraps.
My understanding is that there’s a 416R stainless steel match barrel underneath there that is covered with CF. However…95% of the CF doesn’t even touch the steel (only 4 contact points: chamber, before/after the gas block, and near the muzzle).
This creates air gaps that cool the barrel through the perforations.
I was lucky enough to try this out in a new build thanks to Rainier Arms who sent me a barrel for testing.
The barrel was a sight to behold. Even the wife said it was cool…and by now all the barrels and uppers around the house look the same to her.
I tried out the 16.5″ .223 Wylde in 1:8 twist which clocks in at 26.9 oz. Compare that to a standard M4 profile 16″ barrel at 28 oz. If you want to go bull barrel stainless…it can reach 3 lbs (48 oz). I couldn’t find exact numbers since I could only find 18″ bull barrels that are over 3.5 lbs.
My full build which contains all my favorites:
It is a little more difficult to install since there’s no barrel shoulder to gauge where to put the gas block. But if you have an electronic caliper…you should be good.
My go-to Superlative Arms block (this time in .936 for the bull barrel) went on easily after I made a small etch marking on the stainless section of the barrel.
Otherwise with my combo of the Brigand Arms CF handguard…I found that it rubbed the top of the gas block. Which technically makes it no longer free-floating…but I wanted to see how it would shoot still.
What you’ve been waiting for…does it actually work?
I conducted two rounds of tests…one with the touching CF handguard and one with the free-floating.
200 round break-in, targets at 100 yards, and shooting at a fast pace (as soon as sights were back on target) with no cooling down period.
And an assortment of my Best AR-15 Ammo.
If these were my regular groups with some cool-down and a slow steady shooting pace…I’d be a little disappointed. But I wanted to test how the heat dissipation worked and how it would perform in a little more competitive arena.
In that regard…I’m pretty impressed. It was pretty happy with Wolf Gold (the cheapest ammo) and very happy with Gold Match ($$$).
I also shot 30 rounds as fast as I could at the range and held the barrel. Only warm!
In my second round of tests on another range day, I used the Midwest Handguard and Aero upper. And a new Triggertech trigger which I actually like the most now.
And the results were on par…
All in all…pretty happy about the groups when I was shooting as fast as I could get on target with no cool down.
I’m sure if I started hand-loading I could really close up the groups. But it’s a pain to prep .223/5.56 brass so I stopped doing that. But even with this I was ringing steel at 300-400 pretty easily on a 1-6x scope.
No failures of any kind in the ~400 rounds I shot through.
Great groups when you consider shooting with no cool down and as fast as I could get back on target. A 5 would be consisten sub-moa even at high speed.
I’d make it a 10 if I could. But it really stands out…especially with the sweet carbon fiber drilled holes.
Bang for the Buck: 3.5/5
It’s $500…would I count it as double a really high quality 16″ Wylde barrel? Probably not. But if you’re at the top of your game or want an unfair advantage in relation to your groups opening up due to heat…this could be it. However…the most affordable out of other CF options.
Overall Rating: 4.5/5
I believe the hype of carbon fiber barrels now.
Take a lightweight bull barrel profile with great groups at speed…and you have a winner. If you have the coin for a sweet new build…check out BSF. It’s definitely my new competition rifle.
Ringing steel at 100 was easy standing up and with a 1x. The rifle was well balanced and once I got the Superlative Arms gas block tuned in…it felt like a pea shooter.
I’ll be reporting back as I get more rounds and comps through it.
Otherwise…check out our other Best AR-15 Barrels for something more bang-for-the-buck for the everyday shooter.
HIPERFIRE announces its new EDT3 (Enhanced Duty Trigger3) AR fire-control group for the AR15/10 rifle.
It completes HIPERFIRE’s enhanced duty trigger line up. Like the other EDTs, it was designed for law enforcement and the designated marksman rifle, OEM rifle builders, NRA service rifle competitors and home defenders as a lower cost, high-performance trigger upgrade.
This trigger features the novel “duplex” trigger bow with two finger pad rests, one high and one low. In the high position, the trigger-pull weights are five and six pounds; in the low position, the weights are four and five pounds. The range limits depend on which hammer spring was installed, red or green, which are both included.
a smooth flat stroke with an equally smooth and very positive reset
Thanks to the EDT family‘s novel mechanically advantaged design, these springs are heavier and more powerful than the alternative MIL-grade hammer spring, and yet the pulls are lighter and more controllable than stock. Like the EDT2’s massive hammer head, more collision power is carried into the firing pin to reliably ignite 308/762 NATO cartridges while still exhibiting faster lock time than stock alternatives.
It’s a HIPERTOUCH featuring only a hint of creep, a smooth flat stroke with an equally smooth and very positive reset that users of HIPERTOUCH FCGs have come to appreciate.
The MSRP is $99.

HIPERFIRE announces its new EDT(Enhanced Duty Trigger) AR fire-control trigger. This fire-control group is designed for law enforcement, OEM rifle builders, NRA service rifle competitors, and home defenders as a lower cost high-performance trigger upgrade. This single-stage trigger is an extension of the enhanced duty trigger introduced at the end of 2014. It sports two user-adjustable trigger weights of 4½ and 5½ pounds by simply interchanging two hammer springs.
Thanks to the EDT‘s novel mechanical advantaged design these springs can be, and are, heavier and
more powerful than the alternative MILgrade
hammer spring. Noticeable is the EDT’s more massive hammer head compared to the EDT designed to carry more collision power into the firing pin to reliably ignite

Tarheel 3-Gun invited HIPERFIRE’s match sponsorship early in 2013. Since then, shooters from around the country have won HIPERFIRE’s triggers off the prize tables and compared shooting notes that has established HIPERFIRE’s good reputation not only for trigger design innovation, but most importantly
performance and reliability. HIPERFIRE is very appreciative of Tarheel 3-Gun’s
role in cementing HIPERTOUCH triggers’ place in high performance shooting.
So, HIPERFIRE and Tarheel 3-Gun have now taken the next step to jointly
promote a new signature trigger and further promote the shooting sports in general, because as we all know, shooting the best equipment is not just for 3-gun.
