FAQ
What type of ammunition does the MD10L use?
The MD10L is chambered for .308 Winchester and 7.62 NATO cartridges. Use quality factory ammunition for best reliability and accuracy.
Is this rifle California-compliant?
No, the standard MD10L ships with a 20-round magazine and standard features that do not meet California’s AWB requirements. Check local laws before ordering.
Can I mount a suppressor on the MD10L?
Yes, the 16-inch barrel has standard 5/8×24 threads, allowing direct attachment of most .30-caliber suppressors. Always use a muzzle brake or flash hider with appropriate thread pitch.
How do I clean and maintain the fluted barrel?
Clean the bore and chamber with a standard .308 cleaning kit. Use a nylon brush to remove carbon from flutes, then apply a light coat of CLP to prevent rust.
