Build Time: 6–9 Months | Precision-Crafted | Made in the USA
“In Stock” does not mean ready to ship. It means we have all required parts on hand and can place you into the active 6–9 month build queue.
Your RA5KSD is built from receiver flats up, hand built, fit, and tested, one at a time, by one gunsmith.
The Ronin Arms RA5KSD is not just another clone or conversion—this is a true integrally suppressed K platform, engineered from the ground up for elite suppression, flawless reliability, and uncompromising performance.
Every RA5KSD is handcrafted from start to finish under our core philosophy:
“Accept No Imitations. One Gun. One Gunsmith.”
The result? Precision-fit components, smooth cycling, and a purpose-built system that performs exactly how it was designed to.
