Montana-based manufacturer Rex Silentium is offering up a unique way for customers to buy suppressors – Bitcoin. Obviously, any NFA controlled item needs to follow the proper legal process of transfer and ownership, but it appears that Rex Silentium is the first manufacturer in the industry to accept cryptocurrency. Because of the paperwork, recording keeping and ATF processes involved in silencer ownership, using a payment form like Bitcoin will probably do little to obscure your identity. But more options are usually a good thing.

Additional details are listed below.

Our CoinPayments.com cryptocurrency payment gateway is now fully functional and ready for use. This is a great way to use your crypto directly without having to convert it on an exchange first! We accept Bitcoin, Bitcoin CASH, DASH, Litecoin, Ethereum, Zcash, Monero, Ripple and many more!!!

Rex Silentium – Fidelis

The FIDELIS suppressor boasts some serious suppression. The design is suppression-centric. What good is a suppressor if it does not suppress the sound signature significantly? We have also incorporated a lower back-pressure design to allow for use on many different semi and full automatics. Users will enjoy the benefits of zero impact shift in addition to the impressive sound reduction.

The FIDELIS has been roundly tortured for months in rigorous testing with thousands of rounds. Made from 100% 17-4PH Hardened Stainless Steel, the FIDELIS can withstand limited bursts of full-automatic fire. It will last a lifetime on semi-auto and bolt action rifles. This is a precision suppressor ready for use from 1000 yards or more to running-and-gunning your favorite match!

The 30 caliber will work with all calibers down to 22 caliber.
