Falkor (SI Defense) Releases New Components

Falkor Defense (formally known as SI Defense) has released a variety of new accessories for the Modern Sporting Rifle and other platforms. The new accessories are the product of their “ShadowWorks” research and development team.


For the MSR (AR-15) platform, Falkor’s MACH charging handle system is now available for order. The charging handle is fully ambidextrous with mirrored extensions on both sides of the handle. Construction is of 7075 Aluminum, anodized black, with laser engraving. The MACH series is available for both the intermediate cartridge AR-15 and its caliber set and the MACH-10 was released for the DPMS LR-308 (Gen 1) platform. The MACH 15 retails for $99 and the MACH 10 is available for $110. 


Taking an interesting break away from the semi-auto world, Falkor has turned  its attention to Glock magazine extensions. The first in the series is the Velocity extension, which takes a standard Glock magazine to the 140mm limit of most common shooting sports series. The extension is compatible with 9mm and .40 magazines (+4 and +2 rounds, respectively) though may not be compatible with your flared magazine well (check out compatibility here). Machined from 6061 billet, the extensions are retailing for $39.99 and are available in four colors: black, sand (tan/yellow), grey, and blue. 


Finally, Falkor has released their MANTIS bipod system. Like the other products, manufactured from billet, the Mantis has both swivel and cant capabilities for shots at unique angles or off of uneven surfaces. The feet are self retracting with “precision adjustment notches”. Interface is via standard picatinny rail. Retail is set at $285.

The above post is my opinion and does not reflect the views of any company or organization.



    Does anyone actually buy this crap?

  • How do people plan on staying in business with this overpriced stuff?

    • Budogunner

      I bet it would cost a lot less without all that laser engraving machine time. I mean, damn….

  • Patriot Gunner

    If you think it’s expensive then you understand the price and not the value. There will always be a market for quality and Falkor makes some of the most high quality ar 15 parts/components out there.

    • Rodney Steward

      Bravo Company Mfg., Inc. makes some of the best BCM Charging handles on the market for $48!! They’re great!!!!

  • Erich Von Topp

    For a hundred bucks it had better pull itself.

    Yes some people like me buy this sort of thing. I have BCM, and Raptor CH, Raptor’s have not bitten me yet. If you have a scope that comes anywhere near the back of your AR receiver, you will appreciate how much easier it is to find and manipulate your charging handle in the heat of a paper target attack. Have I ever handled a regular GI charging handle? Yes in ’65 in RVN and several other years there too, they work, these work better. I don’t know about the Falkor but the new Aero Precision and the older champion BCM can pinch sometimes. I like Raptor’s myself and would have to see a new design ‘in the flesh’ before buying one over a Raptor.
