Safety Harbor SHTF 50BMG 29" Single Shot Upper for AR-15 Lower
Optional Rear Monopod Stock, SHTF Bipod and Carry Handle are available.
The SHTF is a single shot or magazine-fed bolt-action repeater, with an interesting twist; the three- or five-round magazines connect to the receiver on the left-hand side, at the "nine o'clock" position viewed from the rear. This arrangement does not interfere with the fire control group mounted under the bolt and allows a low prone position without a long magazine getting the way. The R50 does not use an AR-15 lower and it is considered a firearm on its own, unlike the uppers from Ligamec and Watsons Weapons; however, the vestigial lower module provides AR-15-like ergonomics and trigger pull. The test rifle came with a 22-inch barrel and weighed in at 21.6 pounds with the scope mounted. The R50comes with a fixed-height non-swivel bipod mounted to the hand-guard, a rear stock mounted monopod and a carry handle. A standard A2 Buffer Tube can be installed to replace the rear stock with a Magpul PRS stock if desired.

“Recently Hank Strange and Peter Palma visited The Safety Harbor Firearms Factory on the West Shore of Tampa Bay in Pinellas County, Florida to take a look at their line of 50 BMG Uppers and Complete Rifles. Including the SHTF 50 Mag Fed Upper Conversion, SHTF 50 Single Shot Upper Conversion, SHF S50 and the SHF R50. These are all very affordable options for the budget minded shooter seeking a 50 BMG option.”
