Bipods have come along way in the past few years. Some of the newer, sturdier designs like the Atlas and Sierra 7 require a Picatinny (1913) rail to mount them to your rifle. If you are shooting an AR-15/M16 style rifle with a rail system, this isn’t much of an issue. However, if you are shooting a bolt action rifle with a traditional stock, you’ll need a rail if you want the fancy bipod.
Accu-shot makes two different Atlas bipod rails, the BT15 and the BT17. Both of these rails are modular, accommodating different spacing of pre-installed QD studs. The BT is 3.35″ long and accommodates hole patterns with 1.76″ to 2.78″ center-to-center spacing. The BT17 is 4.00″ long and accommodates hole patterns with 2.20″ to 3.5″ center-to-center spacing.
Many rifles come with two QD studs on their fore-ends. If your rifle is always equipped with two QD on the fore-end, simply select the appropriate rail for your spacing, unscrew the studs and screw the rail into place.
If you only have one QD stud (or no studs), as is the case with the McMillan A5 stock shown below, you’ll need to install a t-nut.

I ordered the BT17 shown here from Brownells. I happened to have the 10/32 t-nuts and screws required for installation, but if you don’t, most hardware stores will.
To begin, the safe and empty barreled action is removed from the stock. The stock shown here is a McMillan A5, but the techniques used here would be applied to a wide variety of stocks.
While a counterbore certainly makes installation a snap, it is a specialized tool. If you don’t have one, a Forstner drill would work well.
