MOA Rifles is proud to offer Integrated Suppressed Barreled Actions in partnership with SWS Rifles — the world's largest manufacturer of Patented Monolithic Integral Suppressed Barrels (MISB). These are not add-on suppressors. The suppressor is machined as a single, patented monolithic unit with the barrel itself, resulting in a package that is quieter, shorter, and more accurate than any traditional suppressor-plus-barrel configuration. Each barrel is handbuilt one at a time by qualified gunsmiths at SWS Rifles in Needville, TX.
Available as a barrel-only conversion for your existing Remington 700-pattern action, or fully assembled on a MOA North Fork or MOA Extreme actions built by Defiance Machine.
⚠ NFA NOTICE: These barrels are registered NFA items (suppressors) and require a Form 4 transfer. MOA Rifles is a licensed FFL/SOT dealer and will handle the full transfer process. Questions? Call us at 541-526-1820.
