BT70: Atlas® M-LOK® Adapter
The BT70 Atlas M-LOK Adapter is the interface between any NC (No Clamp) Atlas bipod and an M-LOK forend. It attaches semi-permanently and keeps a low profile, adding minimal length (3.15") and width (1.11") to the forend without the bulk of a full Picatinny rail section. If you run an Atlas NC bipod on an M-LOK chassis or handguard, the BT70 is the correct solution. $34.95.

Key Features
Modern precision rifle chassis and AR-platform handguards overwhelmingly use M-LOK for accessory attachment. Atlas NC-series bipods are designed to mount to a 17S-spaced stud interface. The BT70 bridges these two systems cleanly and without the elevated rail profile that a full Picatinny rail section would add. It is the preferred solution for shooters who want the Atlas bipod on an M-LOK rail and want to avoid adding a Picatinny section just for the bipod. The semi-permanent installation means it stays put under recoil without play or migration.

Frequently Asked Questions
Most shoppers have a few questions before they add the BT70 Atlas M-LOK Adapter to the cart. The answers below cover how the options compare, what fits your rifle, and blemished units, so you can order the right setup the first time.
Which Atlas bipods work with the BT70?
All NC-series Atlas bipods: BT10-NC, BT46-NC, BT47-NC, BT65-NC, BT69-NC, BT72-NC, and BT35-NC. It does not work with LW17 lever-mount versions, which already have a Picatinny clamp built in.
Is it permanent?
Semi-permanent. It is designed to stay in place and resist movement under recoil, but it can be removed without damaging the forend.
Can I use it with a Picatinny-clamp bipod?
No. The BT70 provides the NC bipod mounting interface. For a Picatinny-clamp bipod, use the BT73 M-LOK Rail or BT80 M-LOK Flush Cup Rail to add a rail section to your M-LOK forend.
What is the difference between BT70, BT73, and BT80?
BT70 is a direct NC bipod mount to M-LOK. BT73 adds a Picatinny rail section to M-LOK. BT80 adds a Picatinny rail section plus a flush cup. Use BT70 if you run an NC bipod and want low profile. Use BT73 or BT80 if you need a Picatinny interface for a lever-mount bipod or Accu-Shot PRM.
What does Blemished mean?
Cosmetic factory seconds. Minor finish marks, fully functional, full no-fine-print lifetime warranty, sold at a discount.
Will it fit my chassis forend?
If your chassis forend has M-LOK slots (not KeyMod, not standard Picatinny), the BT70 will fit. Confirm M-LOK compatibility with your forend manufacturer if unsure.
