Heavy Duty Front Rail with Internal Nutplate.
Shown at left with Bobro Bipod (Not Included)

	Heavy duty Front Rail with Internal Nutplate and QD Stud for Harris QD Bipods - P/N 140063 Shown with original USGI sling swivel The Heavy Duty Model with the optional QD Stud  shown at the left takes advantage of the Sadlak Internal Oval Nutplate  (as used on our QD Post Assembly) using two socket head screws installed externally through the two counterbored holes in the rail.  This model allows the removal or replacement of the rail without removing the stock.  Depending on the stock, initial installation of the internal nutplate may require Dremel work to recess  the oval plate flush to the inside surface.
As illustrated at the right, your original USGI sling swivel is securely held in place by the grooves on the underside of the rail
The internal nut plate supplied with the Heavy Duty Fron Rail is significantly stronger than screws and washers and will take the additional load from the bipod without danger of splitting or cracking the stock	The Nutplate is installed in the thickest area of the stock

Once the HD Front Rail (140062) is installed you have flexibility of attaching a clamp-on type Bi-Pod or,  with Heavy Duty Front Rail with QD Stud (140063) a Harris QD type bipod.   All hardware and screws have mil-spec. Manganese Phosphate finish. The internal Nut Plate can be further supported by permanently bedding it into the stock using Devcon Steel Epoxy or other bedding compound.
