The Sight-Bloc is manufactured from Range Systems patented rubber composite made entirely from recycled rubber particles. Unlike sandbags, which often shift, leak or absorb water, the Sight-Bloc provides a molded rubber construction that will not freeze, absorb water, or decompose, and always provides a stable and sturdy rifle shooting position.
With portable metal gun rests, or with sandbags, it is often challenging to find the correct height to properly sight in your rifle. The multi-level Sight-Bloc provides the shooter with three different height rests. The recessed rest offers heights of 4 inches, 7 inches, or 9 inches. The 9 inch high rest position is ideal for benching ARs and AKs fitted with 30-round magazines. The Sight-Bloc is currently being used by the US Military and law enforcement agencies throughout the US.
The Range Systems Sight-Bloc weighs 14 pounds and its sturdy construction will last a lifetime.
