Best bipod for long range & PRS
Super CAL Series · BT72
Super CAL Atlas® Bipod
The Super CAL is the CAL system scaled up for large-caliber and extreme long range (ELR) rifles. It carries every design principle of the CAL -- 63-degree adjustable preloaded cant with no pan, non-rotating legs, and Hold What You Move Technology -- in a platform approximately 50 percent larger than the standard CAL series. At a 14.75-19.37 inch footprint, it is built for the .50 BMG, .375 CheyTac, .416 Barrett, and similar cartridges that demand maximum stability and a wider base. If your ELR or big-bore rifle needs a bipod that does not flex, shift, or drift, this is it.

Mounting & Compatibility
Tell us what your rifle has up front and we will show the exact part you need, with the price.
Picatinny
Mounts directly to any Picatinny rail using a two-screw clamp assembly, or the ADM-170-S lever for quick-detach.
M-LOK Handguard
Add the BT70 M-LOK adapter to run any NC (no clamp) model on an M-LOK handguard, no Picatinny section needed.

Key Features
The Super CAL (BT72) scales the no-pan CAL concept up for heavy rifles: bigger joints, stronger legs, the same locked stillness.
Built for Heavy Rifles
Sized and strengthened for big magnums and ELR builds.
Pan Removed by Design
No pan joint means nothing to drift under a heavy rifle's recoil.
Locking Cant
Level the rifle and lock it. The setting stays put, shot after shot.
Five Leg Positions
0, 45, 90, 135, and 180 degrees, including the patented 45-degree.
ADM Lever Option
LW17 models ship with the ADM-170-S quick-detach lever installed.
Quick-Change Feet
Runs the 5-H / Super CAL foot family — rubber or Raider cleats.
Made in the USA
Machined in Kansas from 6061-T6 with Type III hardcoat anodize.
Lifetime Warranty
No fine print. If it breaks, we fix it. Built to outlast the rifle.

Frequently Asked Questions
Most shoppers have a few questions before they add the Super CAL Atlas Bipod to the cart. The answers below cover how the options compare, which option to choose, and what fits your rifle, so you can order the right setup the first time.
What is the difference between the Super CAL and the standard CAL?
The Super CAL is approximately 50 percent larger than the standard CAL series. Footprint is 14.75-19.37 inches versus 9.0-16.5 inches for the standard CAL. It is built for large-caliber rifles (.50 BMG, .375 CheyTac, .416 Barrett) where the wider base and additional mass matter. Both have 63 degrees of cant and no pan.
Are the Super CAL feet the same as CAL feet?
No. The Super CAL uses BT55, BT66, and BT75 feet, which are sized specifically for the Super CAL and 5-H series. They are not interchangeable with V8, PSR, or standard CAL feet. Order the correct feet when upgrading.
Which mount type should I choose for the Super CAL?
If you use Picatinny and want fast removal, choose the ADM-170-S Lever (BT72-LW17). If you run a permanent Picatinny setup with no need for rapid changes, the 2-Screw (BT72) saves money. If you run ARCA-Swiss, choose No Clamp (BT72-NC) and pair it with your ARCA clamp.
Is the ARCA Spigot Extension required for the Super CAL?
It depends on your rail geometry. The Area 419 ARCALOCK Spigot Extension ($30.00) provides additional clearance between the clamp body and the larger Super CAL footprint. Check your setup before ordering -- it may or may not be needed.
What does blemished mean?
Blemished units are cosmetic factory seconds with finish imperfections only. No structural or functional difference. Full no-fine-print lifetime warranty. Stock is very limited at this product level.
Is the Super CAL made in the USA?
Yes. Designed, machined, and assembled in the USA by B&T Industries. CAGE code 3L7F2.
Can I use the Super CAL for ELR competition?
Yes. The Super CAL is purpose-built for ELR applications. The wide footprint and locked-cant design are exactly what ELR shooting demands. Verify your rifle's forward rail mounting hardware can handle the bipod weight and recoil forces for your caliber.
How do I confirm my Super CAL is authentic?
Buy from accu-shot.com or a verified authorized dealer. Authentic units have Mil-Spec finish quality and correct B&T Industries markings. Contact B&T Industries directly with any concerns.
Which Atlas bipod do I need for my rifle?
Start with two decisions: the series, then the mounting method. For the series, decide whether you want pan and cant or cant only. The V8, PSR, and 5-H pan and cant; the CAL and Super CAL are cant-only, which keeps the bore perpendicular to the legs for added rigidity at long range. The V8 is the original all-around bipod, the PSR is the hard-use SOCOM-contract version, the 5-H is the heavy large-caliber model, the CAL is the competition cant-only model, and the Super CAL is the oversized cant-only model for ELR and big bores. Once you have the series, choose the mounting method below. Our Atlas Bipod Comparison Chart lists every model and spec side by side.
What is the difference between the mounting options -- Two-Screw Clamp, No Clamp (NC), and Quick-Detach Lever (LW17)?
The bipod is the same in every case; only the clamp that joins it to your rail changes. Two-Screw Clamp: Picatinny rails only, bolted on with a flathead. It is slower to install or remove, so it suits a bipod dedicated to one rifle, and it saves weight, bulk, apex height, and cost. No Clamp (NC): ships without a clamp and with a bare 17S mounting pattern (two holes 1.100" apart, 10-32 threads). You supply any 17S-size mount -- a Picatinny lever, an ARCA-Swiss clamp, or our BT19 AI Spigot or BT70 M-LOK adapter -- so it is best if you run ARCA or already own a 17S clamp. Quick-Detach Lever (LW17): includes a lever clamp (the ADM-170-S on the V8, PSR, CAL, and Super CAL; the larger ADM-5-H on the 5-H) that hand-tightens on and off any Picatinny rail without tools and adjusts to in- and out-of-spec rails -- best if you move one bipod between rifles. If none of these fit your rifle directly, you may need a rail or adapter; see our Atlas Bipod Rail Comparison Chart.
Is there an Atlas bipod that attaches directly to a sling stud?
Not directly, but our BT81 Lil' Brandi sling-stud-to-Picatinny adapter mounts to a traditional stock without disassembly, drilling, or damage, giving you a Picatinny rail for any clamp-style Atlas. If your stock has two sling studs, we recommend our BT15 or BT17 Picatinny rail instead. For a single-stud synthetic or wood stock, a gunsmith can drill a second hole to install a rail. We strongly recommend a competent gunsmith for any firearm modification.
What do I need to mount an Atlas bipod?
The most common path is a Picatinny rail on your rifle, which then accepts any Two-Screw or LW17 lever Atlas. We offer Picatinny rails for general-purpose, Anschutz, Freeland, free-float tube, M-LOK, and other applications -- see the Atlas Bipod Rail Comparison Chart. The second path is a No Clamp (NC) Atlas, which takes any 17S-size mount you supply, or mounts directly to our BT19 AI Spigot or BT70 M-LOK adapter. We strongly recommend a competent gunsmith for any firearm modification.
My tension knob is too tight. How do I loosen it?
A stiff tension knob is common from the factory. Install the bipod on an unloaded rifle, turn it upside down or rest it on the buttstock with the muzzle up, deploy the legs to the 90-degree position, and with a hand on each leg work the pan side to side. It should loosen with use. If it is still too stiff afterward, contact us.
