This video details how to build a functional 50 BMG rifle on a budget, primarily by utilizing an AR-15 lower receiver with a specialized Big Kahuna 50 BMG upper. The build can be achieved for approximately $1,800, excluding optics and bipod, making it significantly more accessible than traditional high-end 50 BMG platforms. Key steps involve replacing the AR-15 hammer with an upgraded component to accommodate the larger caliber and ensuring compatibility with the AR-15 lower.
This short discusses Palmetto State Armory's (PSA) concept guns revealed at Shot Show 2025, including potential production of a 50 caliber sniper rifle. The rifle is noted to resemble a Barrett 50 cal, and PSA's participation in a public poll for gun production suggests consumer demand will drive which concepts become reality.
