Radical New Swallowtail Stock from SEB

Seb’s Swallowtail Stock
A while back, Sebastian Lambang, creator of the Seb Coaxial Rest, created a radical “swallowtail” short-range benchrest stock. This innovative prototype has two wings on the underside of the rear buttstock. We think Seb has come up with a design that is not only an engineering tour de force, but also a stunning example of modern industrial design. In short, it’s a beautiful piece of work.

No, You Can’t Buy One
This stock is a one-of-a-kind unit created by Seb for his own use. At this time he has no plans to build similar versions for sale. Seb told us: “I made the stock for my own purpose, not to intend to sell it.”

The new stock features a 3″-wide rear toe section of the buttstock. The two legs or wings provide exceptional stability for the stock. This “swallowtail” design has a hollow section in the middle. We initially thought this was designed to work with a pyramid-type rear sandbag with a single rear ear. That’s not the case. The stock is intended to work with a two-ear rear bag, with the ears set 3″ apart (see top photo). The area between the rear “wings” was left hollow to save weight. Addtionally, the hollow region allows Seb to place extra weight in this area to balance the gun, or to bring it up to 13.5 lbs. for Heavy Varmint class.

The front of the stock, just forward of the action, features a truss-like architecture that provides extra rigidity in the vertical plane. This allows the front section to be of minimal height, yet still be plenty stiff. Oval cut-outs in the sides of the fore-end lighten the stock structure and also provide improved air circulation for barrel cooling.
