Description

1.375-24 Bravo pattern direct thread mounts, 17-4 H900 stainless steel. Except for the lightening holes drilled from the front, these are machined in a single set up from solid bar stock to ensure all critical features are concentric and aligned. These are properly counterbored for installation on AR barrels and others that lack a rear undercut.

Flange diameter: 1.5″
Flange thickness: .2″
Overall height: .65″
Weight: 2.4-2.8 oz

These mounts install/remove with 1.5″ or adjustable spanner wrenches.  We recommend the OTC 4791 adjustable spanner wrench, which will work with many mounts & adapters of varying diameters as well as some suppressor bodies.


Unless otherwise specified, 1.375-24 Bravo direct thread mounts are THROUGH THREADED; they DO NOT have an internal shoulder to register on muzzles.   If you need an internal shoulder in a direct thread mount, please contact us about custom parts.   M14x1 LH Bravo mount has a rebated register face so that the flange does not contact the front sight tower.

In stock Natural finish or Black adapters ship 1-2 business days. Other color options add up to 10 business days.

    Fit and finish are awesome! I got this 18mm for my factory CZ Scorpion EVO3 so that the suppressor would sit the absolute closest to the rail as possible. It did just that and looks great.

    I've recently purchased a ruger m77 African in 375 ruger and a hybrid 46 suppressor to go along with it. While waiting I started searching for a thread adapter for 5/8-18 x 13.75-24. There were no factory options, which led me to Ecco. I ordered the adapter and it was shipped immediately, I received it a few days later. The adapter is marked with the threads so I always know the threads, which is ideal. The black finished is great and all but spinning it onto a rifle is so satisfying! This is a testimony for the high quality cut of the thread. One quick flick of the finger firmly shoulders the adapter.

    The ECCO Machine 1.375-24 HUB mount is excellent quality, fit and finish. It fits my YHM suppressor perfectly and adapts to my KAK .578-28 barrel perfectly. Their response time and shipping are fantastic.

    Well made adapter, flawlessly finished. and one of the few I could find to adapt a Ruger American Range Rifle in .450 Bushmaster 11/16-24 to a HUB adapter.

    This was just what I needed for a customer's setup. It is very well made and half the price of the only other option I could find for this particular combo, a Q The Fix 8.6 without the Cherrybomb and equipped with an AB Suppressor Raptor 8 .338. Highly recommended!

    Amazing quality, fit, and finish. Matches up perfectly with my dead air primal to mount to my trapper. Works perfectly with the factory wrench, and is 2/3 the price of anyone else. Bravo Zulu again Ecco.
