POSI-LOCK
Some things — like accuracy — should never change. Which is why Burris invented Posi-Lock®.
Posi-Lock replaces the bias springs that hold a scope’s inner tube in place with a retractable steel post. It locks the inner tube, and your accuracy, firmly in place. You get accuracy and dependability you can't find anywhere else.
Available as an option on Euro Diamond,™ Signature Select,™and Handgun scopes, Posi-Lock is the best accuracy insurance a shooter can buy.

• Posi-Lock is a coil-spring assisted retractable steel post that firmly and & securely locks accuracy into place.

• Once the reticle is zeroed, the covering tube (red) replaces the internal spring (green) & locks the inner tube in place.

• All scopes have one spring that allows the adjustment of the reticle. Some of the competition competitors offer a double spring whereas the double spring is the STANDARD for all Burris products.

• As an optional, it’s possible to have the special Posi-Lock system.

• Posi-Lock scopes remain perfectly zeroed year after year even during transportation.
