BT22: Atlas® Leg Extensions
Atlas Leg Extensions raise the working height of your V8, PSR, or Gen 2 CAL Atlas bipod for sitting, kneeling, and elevated positions where the standard bipod leg range is not enough. Two options: the BT22 fixed extension adds a solid three inches of elevation, and the BT85 Adjustable Leg Extension delivers a 7.125" to 12.0" range across nine positions. Both accept compatible Atlas quick-change feet. The BT22 and BT85 are stackable for maximum height, and the BT22 carries an NSN. Sold in pairs.

Built to a Standard
Key Features
Standard Atlas bipod legs cover approximately 4.8" to 9.1" of elevation depending on model and leg position, which covers prone shooting on flat ground. Sitting, kneeling, shooting off a vehicle, shooting over tall grass or brush, or any elevated position needs more. The BT22 provides a clean three-inch boost that costs almost nothing in weight (1.8 oz per pair) and gives PRS competitors the option to engage targets from a seated position without abandoning the bipod. The BT85 gives nine positions across a five-inch range for shooters who need to dial in height precisely on unknown-distance or multi-stage matches where positions vary. Stacking both extends the system further for extreme elevated positions.

Knowledge Is Power
Frequently Asked Questions
Before you buy the Atlas Leg Extensions, it helps to settle a few details. We cover how the options compare, what fits your rifle, and foot options below so you can choose with confidence.
Which bipods are compatible?
V8 (BT10 series), PSR (BT46/BT47 series), and Gen 2 CAL (BT65/BT69 series). Not compatible with 5-H (BT35) or Super CAL (BT72).
Can I stack the BT22 and BT85 together?
Yes. Installing both gives you the BT22 fixed boost plus the BT85 adjustable range stacked on top of it, for maximum combined height.
What feet work with the leg extensions?
Group 1 feet: BT32 Standard Rubber, BT23 Ski Feet, and BT74 Raider Cleat Feet. They attach to the bottom of the extension with the same spring plunger system as the bipod leg.
How does the BT85 adjust?
The BT85 has nine discrete positions across its 7.125" to 12.0" range. You set the height by indexing to the desired position.
What does Blemished mean?
Cosmetic factory seconds with minor finish marks. Fully functional, full no-fine-print lifetime warranty, sold at a discount while stock lasts.
What is the NSN on the BT22?
NSN 1005-01-641-0369 allows military units to procure the BT22 through standard supply channels.
Do leg extensions add any wobble or instability?
No, when properly installed the extensions are rigid. The spring plunger locks the extension in place the same way it locks the foot.
