Description
The Hornady Black 7.62×39 111gr MonoFlex SBR is built specifically for what short-barreled AK and AR platforms need. This isn't a one-size-fits-all cartridge trying to work in everything from a rifle to an SBR. It's engineered with subsonic optimization in mind, meaning the bullet performs exactly as intended when fired through barrels that run 6.75 to 11.5 inches. That matters because velocity changes dramatically in shorter packages, and most standard ammunition won't expand properly at those reduced speeds.
What Makes the MonoFlex SBR Work
The bullet itself is all-copper and completely lead-free. It features a polymer Flex Tip that initiates expansion immediately on impact while the monolithic copper construction retains around 95% of its weight as it passes through. This combination means you get deep, consistent penetration without the weight loss that plagues some expanding bullets. The secant ogive profile keeps flight efficient downrange, and the broad expansion diameter (around 0.73 inches in testing) provides energy transfer without excessive over-penetration.
Performance You Can Count On
This load works in standard 7.62×39 rifles too, despite the SBR name. Whether you're running an AK-47, SKS, or longer-barreled AR platform, the MonoFlex SBR still produces solid terminal ballistics at higher impact velocities. The Hornady Black line uses premium brass cases that are reloadable, high-quality primers, and carefully selected propellant. Everything is manufactured in the USA and assembled to Hornady's standard quality controls.

Frequently Asked Questions
Will the MonoFlex SBR work in a standard-length AK-47 or longer rifle?
Absolutely. While the SBR designation indicates it's optimized for short barrels, the MonoFlex SBR performs reliably in full-length rifles and carbines as well. The bullet expands properly at both reduced and full velocities, making it versatile across different platform lengths.
Why is this load subsonic-optimized?
Short-barreled rifles lose velocity compared to standard-length barrels. The 111-grain MonoFlex SBR is specifically designed to expand and perform reliably at these lower velocities. This is especially important for suppressed platforms where subsonic performance is critical.
Is the brass reloadable?
Yes. Hornady Black ammunition comes in reloadable brass cases, which is one of the reasons the line is popular among handloaders. You get quality components plus the option to reload and reload.
Why is this ammunition lead-free?
The all-copper monolithic construction eliminates lead entirely, which makes this ammo suitable for hunting on land that restricts lead ammunition. The lead-free design doesn't sacrifice performance or terminal ballistics compared to lead-core alternatives.
