    I received my alpha direct thread mount, and it is engineered and manufactured perfectly. I’d rate it better than SilencerCo’s and I received it quickly. Kudos to ECCO!

    So glad I found EccoMachine.net! I couldn’t believe it when SilencerCo did not make the two Alpha direct thread mounts I needed for my Omega 45K. The ones I received from EccoMachine fit like a glove and cost much less than SilencerCo’s. I highly recommend! #BOYCOTTGoDaddy #BOYCOTTPayPal
