M-43 Carbine (Gas impingement):Gilboa® M-43 was developed for organizations that presently use firearms chambered for the 7.62x39mm cartridge, so they may benefit from the added value of upgrading to the modern Gilboa® system while retaining their standard-issue magazines, stock ammunition, vests and web gear.The upper and lower receivers of the Gilboa® are fully machined from solid aircraft aluminum alloy billet (7075-T6) and then hard anodized to ensure a stronger, more durable firearm with no dimensional inconsistencies.
