Investment Opportunity

Due to the international demand for light-weight ammunition there are currently 3 companies making polymer-cased .50 BMG ammunition but without a light-weight .50 caliber weapon to match.

St. George Arms’ award-winning LEADER 50 A1 is still the only rifle which fulfills that requirement (sales inquiries to date exceed $5,000,000)

Qualified investors interested in this unique opportunity to put the LEADER 50 A1 into full production — and the development of a light-weight .50 BMG squad automatic weapon — please email [email protected] for more information.

Gas vs. Recoil

The award-winning Leader 50 A1 is lighter in weight and more accurate than competing recoil-operated designs due, in part, to its gas operation and fixed barrel. This eliminates the need for a heavy forged or machined steel receiver to support the recoiling barrel. The action stops at the midpoint of the receiver against the barrel extension, so no spring or hydraulic recoil buffer is necessary.

The straight-line construction and action springs positioned forward and below the centerline of the bore ensure that the muzzle does not climb. These features, together with an efficient muzzle brake, keep felt recoil to a minimum.

Selecting recoil to operate a modern, man-portable, magazine-fed .50 BMG rifle is antiquated. These rifles with moving barrels are obsolete regarding weight, inherent accuracy, and cost of manufacture — which is reflected in the high retail price.
