What is a Lok-Bolt? Is chop a thing of the past?

What is a Lok-Bolt? Is chop a thing of the past?


In the early days of magfed design, the markers were plagued with chopping—the paint would only partially seat in the chamber before the bolt came forward again, pinching the ball and "chopping" it in the chamber. This plagued almost every magfed design—and markers with gravity-feed hoppers as well—until we developed the Lok Bolt™.
Initially available only for our award-winning T68 and the all-new 468, the Lok Bolt™ is now available for the Magfed Conversion Kits as well!

The Lok-Bolt™ is one of the most innovative designs in the industry. It provides a purely mechanical solution to overcome that "chopping" phenomenon, and it works in all weather—there are no lasers to fry, no batteries to drain, no fragile circuits to baby... The Lok Bolt™ is purely mechanical, and built tough enough to thrive in scenario paintball. That makes the Lok Bolt™ a must-have feature for military units conducting force-on-force training, and for recreational paintball players alike!

MCS is proud to announce that chops are a thing of the past. We have exclusive technology that completely eliminates chopping, no matter your cyclic rate—even in full auto—and no matter what angle you hold your gun. That technology is the Lok Bolt, which we put in every 468 and offer as an upgrade to all of our MKP MagFed Conversion Kits.

The Lok Bolt uses a simple, purely mechanical approach to ensuring that every projectile you shoot makes it safely out of your chamber and into your barrel…and downrange straight at your target.

MCS's lead designer, Omar Macy, provides a look inside this crucial technology in this video:

At some point, you'’ve stopped shooting paint and started shooting splooge and shell fragments. That’s not a very effective way to overcome your opponents, and means that somewhere inside your gun is a sticky, game-stopping mess. Sometimes that happens in the barrel, and is called a “barrel break.” Those messes are bad, but you can clear them with a squeegee. They happen when you over-pressurize the ball due to a velocity spike, an abnormally large or humidity-swollen ball, or because debris fell into your barrel. Clean it, and move on.

But when that goo is all over your chamber? That’s the tell-tale sign of a chop, which happens when your bolt closes on a partially-seated, or mal-formed, or humidity-swollen paintball. Rather than hopping into your barrel, the partially seated ball gets crushed by your bolt, and you’re immediately out of the action until you can thoroughly clean the chamber. The over-sized and swollen paint, like your paint becomes after too long at camp during hot summer games, might fool the electronic “eyes” on a high-tech gun...but won’t make it out of your gun before bursting all over its internal spaces. It happens in woodsball, in mil-sim, even in tournaments…

…so companies have created high-dollar, high-tech solutions to prevent chops. Those are cute. And they work most of the time, so long as your batteries work, and so long as you don’t knock the wires loose.

Our solution is better, and specifically designed for the realistic guns used in the most realistic games. The MCS Lok Bolt is an all-mechanical, refreshingly simple, battery-free, sensor-free, fool-proof solution that makes chopping a thing of the past. Sound like a big claim?

It is. See for yourself in Omar’s video. The genius in the design is that the Lok Bolt physically restrains your bolt from crushing the paint until a perfectly round, properly formed (not humidity-swollen) paintball is seated in the chamber. And with our MagFed design, where our Mags and DMags hold the paint under constant spring pressure, that ball will be pushed into the chamber and held there securely no matter your rate or fire or the angle at which you hold your gun.

That’s engineered reliability that you can rely on. There’s no such thing as chopping with real firearms, and now, there’s no such thing as chopping with the Lok Bolt!
