The Air Marksman Backbone 30 MOA Long Black mounting rail adds a whopping 457mm of Weaver/Picatinny slots to your FX Impact (M3 and earlier generations).
By replacing the standard mounting rail and guiding plate, the rail acts as a bridge to connect the front and rear sections of your Impact. This ensures a more stable and stiffer whole, which is reflected in more consistent results.
The Air Marksman Backbone 30 MOA Long Black mounting rail is made of aluminum and weighs 600 grams.
|Top-side mount:||22mm Picatinny/Weaver|
