Griffin Armament Announces Revolution Upgrade Program

One of the unfortunate truths of NFA firearms and the long wait times associated with the approval process is that sometimes that can you bought eight months ago and just picked up might already be out of date. With a litany of companies producing suppressors and new releases hitting every few months, it isn’t uncommon for an entirely new release to render your much anticipated purchase “obsolete” (though not really) before you even take possession of it. New releases aren’t the only factor at play, though. Although the changes aren’t always widely published, it’s a fact that leading suppressor manufacturers often introduce multiple updates over the course of a particular model’s lifecycle.

These sorts of intragenerational changes are often kept relatively quiet for a very good and innocuous reason. No matter how minute they might be, any inkling of an upgrade inevitably leads to early/earlier adopter reaction. At best, manufacturers are left with hundreds of requests for upgrades. At worst, they’re accused of ripping off their customers. These sorts of reactions lead even well-intentioned companies to shy away from big announcements with each small revision.

Some news out of Griffin Armament today presents us with a surprisingly unique twist to this discussion. When Griffin came out with their Revolution line of pistol silencers back in 2014, they changed the suppressor game by being the first major brand to release a modular silencer. A good can in its own right, the Revolution’s biggest selling point was the fact that it could be configured into two different lengths by simply removing the blast chamber and swapping the piston housing over to the main tube. As some buyers found out, this process wasn’t quite as easy as advertised.

This is a close-up of the original Revolution. Notice that the piston housing has an exposed, knurled outer ring. Some have found that the knurling doesn’t offer sufficient grip to remove dirty housings when swapping the part between the modular addition and main silencer body. (Image credit: Silencer Shop)

The crux of the issue was the fact that the booster housing left only a small ring exposed when fastened to the main tube or extension. Once tightened down and dirty from use, the piston cage left insufficient exposed real estate for users to get a firm grasp and unscrew the part. This made changing the Revolution’s length surprisingly difficult.

When Griffin released the Optimus suppressor about a year after the Revolution was introduced, they carried over the same booster housing, but with one significant revision – notches. On the circumference of the housing’s outer ring, Griffin added four notches that are compatible with any AR-15 castle nut wrench to assist in installation and removal. This change was carried over to newer Revolution silencers to rectify the issues experienced by some users.

Notice the notches on the Optumus’ piston housing. These were added to the Revolution series at about the time the Optimus was introduced.

When owners of older Revolutions learned of the change, some were outraged. All of a sudden, complaints rang out that and some even accused Griffin of ripping off owners with a faulty product. On some firearms forums, the discussion got quite ugly, but Griffin Armament promised to make the upgrade available to current owners for a fee – which led some users to amplify their rip-off claims.

As of today, the upgrade is finally available. If you own an older Revolution series silencer that has the smooth piston housing, you can now send your suppressor and $145 to Griffin for the upgrade.

The parts that are included in the Revolution upgrade.

While I know some will balk at the idea of paying the manufacturer to “fix” their can, $145 isn’t totally unreasonable. It’s less than the cost of a new tax stamp and having used the Optimus, is probably worth the price. I can absolutely see how the old design might have gotten stuck and the ones on the Optimus (and newer Revolution/Resistance silencers) work very well. I also don’t necessarily see old models as “faulty”. As I see it, Griffin simply found a better way to design the booster housing and chose to incorporate it on current generation suppressors, rather than wait for a new release. I don’t know about readers, but I think their chosen course is preferable, even if it does leave some feeling burned.

If you have an older Revolution and would like to get it upgraded, head on over to Griffin’s website for the details.

    I ordered my Optimus last June and still haven’t gotten my stamp. I’m already just turned off by the whole suppressor thing because of the NFA branch.
