Kraford & Lypt FX Impact Range Extender lets the scope reticle move up to an additional 150MOA. Unlike to No Limit scope rings which are high profile and not integrated, the K&L FX Impact Range Extender keeps the scope closer to the barrel for a more precise shot. Also you can choose the scope rings you like and makes for a lower center of gravity with heavy scopes.
The base of this rail is dovetail, so you are also able to remove the rail and put dovetail rings even closer to the barrel.
The range extender is a top choice for long range shooting AND up close shooting.
