Model X

Model X-800

The X project was our challenge to come up with a new suppressor not just in design but also in the way our industry builds suppressors. The idea was to get away from the norm. X project silencers were not built using the typical tubing and machined endcaps. We started with aircraft grade billet. Taking a solid piece of metal and machining a silencer. No entrance cap, it is an integral part of the suppressor. No spacers, they are machined into the suppressor body. Changing the outward appearance by adding spiral flutes to aid in cooling and to make this suppressor look like one “bad dude”. Stainless steel thread inserts. There were, however, a few things we wanted to keep. We use our tried and true V-Tech baffle and like all Coastal Gun Suppressors built over the past 20 years these units are never sealed. There are two X project suppressors and both are built for multiple caliber use.
