Description

The Strike Industries Mass Driver Compensator (MDC) represents a quantum leap in compensator design. Current designs have largely been unchanged since the 1930s. It’s about time for something revolutionary. The Mass Driver name is inspired by the idea of theoretical mass driver engines in space travel. By ejecting mass, an equal and opposite reaction is generated propelling the space vehicle forward. The Mass Driver Compensator is driven by the hot gasses expelled through the barrel after the round is discharged, and acts as a counter balance system to attenuate mechanical recoil. Barrel mounted compensators add reciprocating mass and increase the moment of inertia to the operating system, which can have a negative effect on reliable cycling of recoil operated handguns. By separating the compensator from the operating components after ignition, the MDC allows for close to stock cyclic speeds, and reduces reciprocating mass. The compensator of the MDC system has a widened bore to reduce baffle strikes and keyholing rounds along with a 2.5mm relief cut at the top of the rear to reduce “lipping” and damage to the face of the pistol slide.

Reliable and dependable
Style: 17548N
I installed a new starter on my 1995 Dodge Ram Cummins, and it has exceeded my expectations. Ive had it for about 20k miles now. Installation was straightforward, and the starter fit perfectly without any modifications. From the first turn of the key, it cranked the engine smoothly and reliably at a great price. Since installing it, my truck starts every time, even in cold mornings, which has been a huge relief. The starter feels durable and well-built, giving me confidence that it will last for years of regular use. It’s clear that this is a quality part designed for heavy-duty performance, just what you need on a classic Cummins diesel. Overall, I’m extremely satisfied with this starter. If you’re looking for a reliable, strong, and easy-to-install replacement for your Dodge Ram Cummins, this one is an excellent choice.

Good quality except for the supplied bolts.
Style: 18493N
So far starter works great. Be careful if you use the supplied bolts. They are not good quality. The last thing you want to do is snap them off in the block. The starter itself really spins the engine over. If it lives long, it's a great deal for the money.
