Perfecting The Remington 870 Shotgun With Vang Comp Systems

May 21, 2026

In this article, we will explore how Vang Comp Systems can improve the performance of a Remington 870 shotgun.

Introduction to Vang Comp

Vang Comp was founded in 1990 by gunsmith Hans Vang in California. The company’s primary goal is to modify shotgun barrels to reduce recoil and muzzle flash, while also improving pattern consistency.

Vang Comp Modifications

The company’s modifications include extending the forcing cone, back-boring the barrel, and porting the barrel array.

Extending the Forcing Cone

The forcing cone is the transition space between the chamber and the remainder of the barrel. A longer and gentler slope helps to reduce recoil and improve pattern consistency.

Back-Boring the Barrel

Back-boring the remainder of the barrel creates a lengthened choke, which helps to protect the pellets in the shot column.

Ported Barrel Array

The ported barrel array vents gases and helps to keep the muzzle level.

Vang Comp’s Impact on Our Remington 870 Police Magnum

We recently had our Remington 870 Police Magnum modified by Vang Comp Systems. The results were impressive, with a significant reduction in recoil and improved pattern consistency.

Conclusion

Whether you’re a seasoned shooter or a new enthusiast, it’s worth considering the options available to improve your shotgun’s performance.
