Kns Precision
The Adjustable Gas Piston System for VEPR Large Caliber from KNS Precision solves one of the AK platform's most persistent headaches: excessive gas cycling. If your VEPR rifle in 7.62x39mm, .308 Winchester, or 7.62x54R is flinging brass downrange 15 feet or more, your gun is running hot—and paying the price in accelerated wear on internal components. This adjustable piston lets you dial in the exact gas flow your rifle needs, taming overgassing and extending the life of your firearm.
Built to work with your existing gas block, the KNS large-caliber piston fits VEPR, AKM, AK-74, PSL, and M92 platforms without requiring a gunsmith visit. Installation takes about 10 minutes—no special tools, no trips to the armorer. That means you can get back to the range quickly and start tuning your rifle's performance to your ammunition and suppressor setup, if you're running one.
Over-gassed AK-platform rifles wear faster, run dirtier, and beat themselves harder than they should. If you've noticed aggressive brass scatter or want to reduce felt recoil and muzzle rise, this piston gives you real control over your gun's gas curve. It's the kind of upgrade that pays dividends in reliability and longevity, especially if you shoot your VEPR hard and often.

Yes. The KNS Precision Adjustable Gas Piston System for large caliber is designed to fit VEPR, AKM, AK-74, PSL, and M92 platforms. It works with your existing gas block without modification.
This system is designed for 7.62x39mm, .308 Winchester, and 7.62x54R. If you run a smaller caliber like .223 Remington or 5.45x39mm, you'll need KNS's small-caliber piston instead.
No. The adjustable gas piston installs in approximately 10 minutes without gunsmith assistance or special tools, so you can get back to shooting quickly.
If your brass is ejecting more than 15 feet away, your rifle is over-gassed. An adjustable piston lets you reduce gas flow, which lessens wear, recoil, and muzzle rise while improving reliability and component longevity.
