Sadlak Industries M14/M1A Heavy Duty Front Rail with Internal Nutplate
Shown with original USGI sling swivel (not included)
The Heavy Duty Model takes advantage of the Sadlak Internal Oval Nutplate 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 Nutplate is installed in the thickest area of the stock
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
Once the HD Front Rail (140062) is installed you have flexibility of attaching a clamp-on type Bi-Pod . 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.
