You show us someone who doesn’t want to own a .50-cal, and we’ll show you a liar. It’s pretty simple: Big boom = big fun. However, that “big fun” usually comes with a hefty price tag attached to it. Most of the .50-caliber rifles we’ve come to know and love start at mid-four figures. They go right on up to well above $10,000. But what if we said you could have your own .50-cal starting at less than $2,000? All you need is an AR-15. Enter the Safety Harbor SHTF 50 upper conversion.

Safety Harbor SHTF 50 Details
The SHTF 50 upper fits any standard mil-spec AR-15 lower and turns it into a .50-cal bolt-action rifle. The video above explains things pretty well. Safety Harbor offers different scope rails and different barrel lengths, as well as a single-shot or mag fed version. Those interested can also buy just the upper or a rifle package with a single-shot lower included.
Scope rails include a 20 MOA Rail, an “Exacto Rail,” a high rail, and a low rail. Barrel lengths include 18 inches and 29 inches. Safety Harbor originally had 22-inch models, but it appears they aren’t available for the time being.
Now, on to the good news: MSRP. The single-shot upper ranges from $1,450 to $1,550. Meanwhile, the mag-fed version retails between $1,850 and $2,000. So, all things considered, you’re saving a ton of cheddar and you still get that big boom we all love. If you’re not convinced, watch the video above.
