The Atlas BT73 M-LOK Picatinny Rail, part number BT73 from B&T Industries, adds a short MIL-STD-1913 Picatinny rail section to any M-LOK compatible handguard, forend or buttstock. It is the simple way to run a two-screw or ADM lever-mount Atlas bipod on an M-LOK rifle.
How It Compares
The BT73 gives you a rail; the Atlas BT70 M-LOK adaptor instead bolts an NC (No Clamp) Atlas bipod straight into the M-LOK slot with no rail at all, which is lower and lighter. If you also want flush cup sling sockets in the same fitting, the Atlas BT80 M-LOK flush cup rail combines both. Bipods to go on it are in our Atlas bipod range.
Ideal For
- Practical and service rifle builds on M-LOK handguards
- Adding Atlas bipod mounting to an AR-pattern or chassis rifle
- Night fox and vermin rifles built on M-LOK forends
- Shooters who want a Picatinny interface rather than a direct M-LOK mount

Frequently Asked Questions
What does the Atlas BT73 M-LOK rail do?
The BT73 bolts into an M-LOK slot and provides a short MIL-STD-1913 Picatinny rail section, so a Picatinny-mount bipod or monopod can be fitted to an M-LOK handguard, forend or buttstock.
Should I choose the BT73 rail or the BT70 M-LOK adaptor?
Choose the BT73 if your bipod has a two-screw or ADM lever Picatinny clamp, and choose the BT70 M-LOK adaptor if you have an NC (No Clamp) Atlas bipod, because the BT70 mounts it directly into the M-LOK slot without a rail.
Is the Atlas BT73 KeyMod compatible?
No — the BT73 is an M-LOK fitting only and will not mount to a KeyMod handguard.
Which bipods will fit the Atlas BT73?
Any bipod with a standard MIL-STD-1913 Picatinny clamp will fit, including the two-screw Atlas models such as the BT10 and BT65 and the ADM lever models such as the BT46-LW17.
What is in the box?
