AR Services

Meridian Ordnance LLC offers our own proprietary, enhanced, forged AR lowers consisting of the MO15E, MO10T, MO9G, and MO9K for our custom work to accommodate calibers including 9mm NATO (both COLT and GLOCK magazine patterns), 5.56 NATO/.223 Rem, .300 BLK, 6.8 SPC II, 6.5 Grendel, 7.62 NATO/.308 Win and 6.5 Creedmoor.

All of our enhanced lowers are available in semi-automatic as well as select-fire (post dealer sample LE/MIL sales only).

Our MO15E rifles and carbines in 5.56 NATO feature our proprietary MO15E receivers and Ballistic Advantage LLC barrels as a baseline. Our built-to-order custom AR rifles, carbines, pistols and machine guns included a wide range of unique, quality features that come standard. They offer a tremendous quality to cost ratio for professionals and amateur shooters alike.

We also offer in house armorer services, Cerakote and Moly Resin refinishing, engraving, receiver lapping, barrel replacement, gas block installation, gas piston conversions, suppressor tuning, handguard/rail timing & installation, refurbishing, general repairs and depot level maintenance.

Jobs are finished when they are finished. All of our projects are generally built-to-order. The nature of custom gunsmithing is not a quick process historically, and we are one of the few small shops in the US still doing custom work, one at time; not production run models. The backlog of work and my reputation earned since starting out in 2004 are testament to our popularity and quality. Each job is different. It requires time and patience to fit and finish most projects correctly. In addition, there are times when the shop is not fully staffed given an ongoing personal commitment with the KY Army National Guard. (I am currently on a mobilization and will not be back in the shop full-time until Fall 2022). Smaller projects, most AR builds and basic services can be completed rather quickly between other, larger jobs. Full, custom AK builds and more involved tasks can take many months to finish due to the long line of customers patiently waiting. Given the volatile nature of the gun industry since April 2020 and the nature of custom work, there is a 20% cancelation fee for any jobs that are canceled before completion which are already underway. Please contact us with any questions.
