BT17: 4″ Picatinny Rail
The BT17 is a 4 inch Picatinny rail section that adds a clean mounting point to your forend, so you can clamp an Atlas bipod to a rifle that did not come with a rail. The extra length gives you room to position the bipod for balance and loading. For shorter setups, the BT15 3.35 inch rail does the same job in a more compact length. Machined in the USA and backed by a lifetime warranty.

Frequently Asked Questions
Still weighing whether the BT17 4in Picatinny Rail is right for your rifle? These quick answers tackle what we get asked most: how the options compare, what fits your rifle, and where it is made.
What is the BT17 rail for?
The BT17 is a 4 inch Picatinny rail section that bolts to a forend with mounting holes, giving a rifle a Picatinny rail so an Atlas bipod can clamp on.
BT17 or BT15: which length do I need?
The BT17 is 4 inches with more room to position the bipod; the BT15 is 3.35 inches and more compact. Choose by your forend length and how much fore-aft adjustment you want.
Does the BT17 fit my rifle?
It mounts to forends with compatible mounting holes. Check your forend's hole pattern, or if your rifle only has a sling stud, use the BT81 adapter instead. Ask our team to confirm fit.
Do I need a gunsmith to install it?
No, if your forend already has the mounting holes; it is a hand-tool install. If your forend has no holes, the BT81 sling-stud adapter is a no-gunsmith path to a rail.
Is the BT17 made in the USA?
Yes. The BT17 is machined in the USA by B&T Industries and backed by a lifetime warranty.
