$71.00

Description

These direct thread mounts allow you to use your 1.125-28 threaded Alpha (also “Harvester .300″) pattern suppressor in direct thread configuration.  stainless Alpha mounts install/remove with our Alpha mount wrench, a 1-1/16 or 27mm 12-point wrench/socket, adjustable pin wrench or hook type spanner wrench.  Our Titanium Alpha direct thread mounts will accommodate AR length tenons of .625″ (5/8”, 16mm).   Unless noted with “MR” for Muzzle Registering, stainless Alpha direct thread mounts are through-threaded (barrel shoulder registering); through-threaded  these will NOT register on the muzzle.   If you need a muzzle registering Alpha direct thread mount that we do not have in stainless, please see if we offer it in our ultralight aluminum version:  https://www.eccomachine.net/product/1-125-28-alpha-ultralight-aluminum-direct-thread-mounts/

M16x1 LH MR mount is designed to work with the Kriss Vector models having that thread.

M13.5×1 LH MR mount is compatible with the Sig MPX & MPX-K having that thread.  Note: it will engage the muzzle, NOT the taper; we do not offer a 13.5×1 LH mount which utilizes the taper.

    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
