F4 Defense – Hunter

(5 customer reviews)


At F4 Defense, we sought a design to set an industry standard in both quality and aesthetics, but that was just a starting point. Our engineers have developed a precision rifle that seamlessly blends form and function. The F4 Defense Hunter features sub-MOA accuracy across all 4 calibers (6mm ARC, .22 Nosler, .204 Ruger, and 6.5 Grendel).

** There will be a $1000 cancellation charge for all SF-10 orders.  We do our best to build and deliver our rifles within the estimated lead times but due to the current climate that is not always possible.

Current Lead Time:  20-24 weeks

Please call (240-808-2314) or email (info@f4defense.com) with any questions.

    I got the EBR with ARS-Lite Rail System. This rifle is amazing and I love everything about it. Customer service is by far the best!

    I was originally in the market for a SR15 until i saw this badass rifle. It comes with all the goodies i wanted + Cerakote finish so i pulled the trigger. The Fit and Finish of the gun is excellent and pretty Solid, the battle steel cerakote that dave recommended me is awesome it looks much better in person. I wasn’t gonna write a review without shooting it but so far i’ve ran thru 300+ rounds on it with no problem its a smooth shooting rifle. very pleased with the company and Dave for keeping me updated and always answering my question within minutes. Amazing Customer Service. you guys got my business

    Waited for months to get my hands on their .224 Valkyrie and after a few days shooting it, it was worth the wait…lol..easy to say now that its in my hands. ..the accuracy is insane…very happy

    I am just commenting on their Customer Service so far and they are Top Notch, Dave has answered all my questions even though I have probably been a Pain in his butt. He has been very courteous and friendly and he has put me on the waiting list for the New Small Frame SF-10 w/ 16″ Carbon Barrel and would not even accept any money until the Rifle is ready to be shipped. From what I have seen and read their new SF-10 .308 it will be a very accurate, reliable and quality Rifle that is one of the Lightest .308’s on the market, Christmas will be coming early for me this year. Thank you Dave for everything and can’t wait to get my new rifle.

    Every year we get a new caliber that features flatter shots at longer distance, better wind bucking attributes, and a harder hitting projectile. I had no idea these cartridges existed. I checked retail price and I see all are OK. Are these truly battle rifle rounds or varmint rounds? I’d go with the heavier Grendle on the principle of tossing a heavier projectile out there. No other reason than that.
