The BD-15 is a 5.56 carbine assembled by Bird Dog Arms in Houston, listed under SKU R3354 as a new gun. It runs a 16-inch barrel inside a free-float rail, so nothing touches the barrel between the receiver and the muzzle, and the adjustable stock lets you shorten or lengthen the pull to suit a heavy jacket, body armor or a smaller shooter. A low-profile gas block sits under the rail, and the muzzle wears a bird-cage flash hider. The supplier lists it as new; the picture shown is a stock image rather than this exact rifle.

For a Texas buyer this is a straightforward home-defense and range carbine built inside the state. Texas asks for no purchase permit, no registration and no waiting period, so once your dealer has your photo identification, a completed Form 4473 and a passed federal NICS check, the rifle goes home the same visit. Federal law sets the floor at 18 for a long gun, and Texas adds nothing on top of that.
