ECCO Machine offers mount conversion services using our patent pending Conversion Pieces for many popular suppressors. We can remove the original unsatisfactory mounting system on your suppressor and convert it to use mounts & adapters in industry standard 1.375-24 Bravo (“H.U.B”, “Omega 300”, “Hybrid”) pattern. For more information, visit our Conversion service deposit page, scroll down to read the whole description and follow the instructions listed to send in for one of our batches.

ECCO Machine offers recoring services for all legal production (Form 4) and Form 1 suppressors. We can employ both serviceable and fully welded non-serviceable core designs, as well as tubeless recores, although not all suppressors have all core type options available due to their construction. We are able to improve your can in one of more of the categories of performance, durability & serviceability, as well as often reducing weight considerably on many rifle suppressors. Full warranty against defects in materials & workmanship.

The price range for recoring is highly variable, but we are generally able to ballpark pretty accurately if you can tell us the length, inside diameter and whether it will be optimized for subsonic/low pressure or high velocity cartridges. Most centerfire suppressor recores end up somewhere between $300-$550, rimfires generally in the $200-$300 range.

We can replace any & all parts except for the main tube/primary tube segment bearing the engraving, and we do have some pretty trick solutions for cracked or catastrophically damaged tubes as long as the engraving is in-tact!

***Please note that we generally do not recore 3D printed suppressors or suppressors with cores plug welded into the tubes. Some exceptions may exist, depending on how difficult it is to salvage the engraved section of the tube which must be retained***

If you are inquiring about recoring services, we need to know the following to answer option & cost questions:

–If a current production suppressor, the make, model, length & caliber, and whether it will be optimized for subsonic/low pressure or high velocity rifle rounds.

–If an out-of-production or Form 1 silencer, we need to know tube outside diameter, inside diameter (if possible), length, caliber, tube material (if known) and whether it will be optimized for subsonic/low pressure or high velocity rifle rounds.

Photographs are also always helpful, especially if we’re dealing with damage.

We cannot add length to your silencer or change the caliber. Overboring to reduce backpressure or mitigate baffle strike concerns is possible, and we can generally shorten by up to an inch, sometimes more if damage makes it necessary.

We offer barrel threading services for most handguns, including unconventional solutions for those weapons which “can’t be threaded”.

RIFLE BARREL THREADING AND TAPERED PISTOL BARREL THREADING HAVE BEEN DISCONTINUED INDEFINITELY

Pistol barrel threading with extension adapter is $110 + shipping for most handguns. Those which require slide face modification to accommodate the adapter are usually $150 + shipping. Makarovs and 1895 Nagant revolvers sent in as complete pistols are $160 + shipping.

We need your upper assembly – slide, barrel, spring & guide rod (if present) – for this service, but not the frame.

Minimum barrel diameters at muzzle for common calibers to be threaded EXTERNALLY for an extension and NOT require slide modification are listed below. Add .02″ for barrels that need to be INTERNALLY threaded for a male/male extension:

.22: .373″
.25: .401″
.30/.32/7.62/7.65: .472″
.38/.380/9mm: .505″
.40/10mm: .555″
.45: .605”

Pistols with no guide rod that have a spring-over-barrel arrangement cannot* be threaded & extended if their barrels do not meet these minimum dimensional requirements. As well, slide modification for a larger diameter extension on a skinny barrel is not always possible.

Some extensions will be blended to the barrel and look like a factory threaded barrel, some will have a flange. This is at our discretion, and the former generally is only done if thread major diameter is at least .05″ smaller than barrel outside diameter. Some rimfire extensions will have a female Torx driver feature, other extensions with a flange will have a 12 scallop feature that accepts a 9/16″ 12-point wrench/socket for 1/2-28 threads or a 5/8″ 12-point wrench/socket for 9/16-24 & .578-28 threads. We do not cut metric threads.

Standard tenon lengths are .4″ for rimfire, .45″ for all others.

*We do NOT cut left-hand or metric threads on barrels*

Extensions are secured with Loctite to prevent them unscrewing with your suppressor and are not meant to be removed with any frequency. It is generally possible to effectively clean the gun with the barrel & slide together by moving the barrel fore & aft and tilting it as you clean.

*It is physically possible to externally thread & extend barrels with an extension diameter as thin as .110″ over bore diameter, but it is NOT recommended and would be done with the understanding that there is no warranty whatsoever, including full disclaimer for any damage or injury as a result of failure if you opt to proceed with an extension smaller in diameter than the minimums above.

CUSTOM PARTS ARE SUSPENDED UNTIL FURTHER NOTICE


Sorry, but we cannot sell anything that would be considered a silencer part unless it is part of a recore for a suppressor we have here for service. This includes tubes/tube segments, baffles (“cups”), spacers & end caps (unless for a production can from a manufacturer who also sells them)
