Griffin’s GP-N™ (General Purpose, Nato) suppressor is a robust, dedicated 5.56mm suppressor which provides secure fitment to common A2 compensator. The A2 compensator is a familiar muzzle device to nearly all AR15 rifle owners. This simple, inexpensive, yet effective compensator has served the military for decades. The Griffin GP-N™ was designed to bring modern suppressor technology to the A2 mountable class of silencers which became commercially popular decades ago with the Gemtech® Halo.
Fully billet machined from 17-4 stainless steel, the GP-N™ offers users with an extremely durable welded general-purpose suppressor. Full H900 heat treatment further increases strength and service life to the product. The mounting collar is QPQ nitrided and the suppressor is spray coated in Cerakote® to provide a smooth, heat resistant, and desirable finish.
Cutting edge materials and composition aren’t the only upgrades to this suppressor. Griffin’s ECO-FLO™ baffles provide substantial blow-back reduction on semi-automatic systems while balancing sound pressure levels at the shooters’ ear and the muzzle to optimize sound performance.
“There are hundreds of thousands of firearms globally that use the A2 compensator. This is a highly fielded, low-cost muzzle device that has served free world military units for decades. This silencer brings modern materials, construction, performance, and durability to this simple, robust attachment system. The objective of this product was to offer a modern suppressor that could provide a direct fitment to those firearms. ”

The Gemtech HALO was a good system. When my unit was issued HALOs no one knew that all the crush washers had to be replaced with shims so we had a lot of endcap/baffle strikes initially. One phone call to Gemtech describing the problem and we had a huge bag of shims in our hands delivered gratis to the other side of the globe in under a week.
Griffin would be wise to emphasize the use of shims over crush washers. I see they are included.
