Finally,
a drop-in solution for taming the notoriously-overgassed AK platform.
The patented KNS AK Adjustable Gas Piston is a replacement for the
AK’s piston head that attaches to the bolt carrier in about 10
minutes with no major gunsmithing or permanent modification required.
The user is granted an extremely wide range of gas adjustment for
suppressed and unsuppressed use, as well as a variety of different
kinds of ammunition.
A
good rule of thumb to determine if our piston will be useful, is if
your gun throws the brass over 15 feet.
This can signify excess gas pushing the carrier back at a higher
velocity and pressure, than is needed for effective operation. Most
(but
not all)
AK’s are over-gassed.
This causes more recoil, more wear and tear, and less
controllability. Many users are surprised to feel the difference in
how their gun shoots with our Adjustable Gas Piston System installed.
Variations
in the AK platform, the use of some after market parts and a
properly-tuned and gassed firearm may
not
greatly enhance the performance and may impede function due to
under-gassing or interference.
We’ve
redesigned and improved the adjustment collar for your AK Adjustable
Gas Piston. With robust collar geometry and the addition of a roller
detent, this version is MUCH stronger and protects all critical
components from impact.
There
is no need to remove or replace your gas block for adjustability.
Just change the piston, and go shoot.
Small
Bore/Caliber pistons are for .223″, 5.56mm, and 5.45mm. They work
better in AK’s of ALL CALIBERS with less excess gas.
Large
Bore/Caliber pistons are for 7.62×39, .308″, and 7.62x54r.
**When
selecting your piston please refer to the chart pictured above to
ensure maximized compatibility with your firearm.**
***A
small percentage of Commercial Spec firearms have the piston welded
to the carrier, instead of the usual Rivet holding in the Piston. We
recommend purchasing a new carrier for the easiest installation.***
****
Vepr and Saiga Pistons will require drilling through the op-rod after
screwing the piston into the carrier, due to variations in the
staking location. These Op-Rods are Phosphated instead of Nitrided to
allow easy drilling.****
