The single most accurate semi auto 17hmr!

Jesse Mathewson (the Survivalist Blog)

“This bad boy is definitely half-inch groups at 100 yards for 5 shots and even smaller than that for 3 shots.”

Nito Mortera (AP2020)

“It is very accurate and will displace the shots exactly where I need them! “I love it! It’s brought the passion of the 17HMR back.”

Eric Mayer (Varminter Magazine)

Varminter.com - Hunt Report

We slay a bunch of marauding prairie dogs and put the GFD 17HMR to the test out in the field, with heat, dust and everything else we run into while roaming the high desert.  The upper functioned well, with no glitches and proved to be very accurate.

The full review and range report will be published on Friday, Nov 10th.
