    My second Sentry!

    Posted by K. Taylor on Jul 3rd 2024

    This is the second one I’ve purchased and own. I’m am out to purchase the new Holosun thermal scope and this rifle will be my designated Coyote Gun for night time hunting as well as night time home defense. I absolutely love this Sentry rifle. The quality as well as the features on it make it the biggest bargain among AR rifles!

    Faxon Sentry 16" 5.56

    Posted by Alex G. on Apr 12th 2023

    Incredibly well built rifle, both aesthetically and quality! I could have never imagined finding a rifle of this quality for anywhere near what I paid. Originally, I was looking to purchase a Daniel Defense, as this is what I was familiar with, having used their rifles throughout my time in Ranger Battalion. Their quality speaks for itself, however, their prices are a bit steep. A buddy of mine encouraged me to check out Faxon Arms, having previously purchased a rifle from them himself. I'm so thankful that he did, because I would have spent substantially more through Daniel Defense, for a rifle that was no better than the Sentury I purchased!

    Sentry rifle

    Posted by John on Mar 11th 2023

    I just got back from my first range trip with my Sentry rifle. I used lancer, magpul, GI, Hexmag, Tapco, and MFT magazines filled with different types of ammo including hollow point. Everything fed perfectly with no issues. Once sighted in the rifle maintained groups even when hot. The rifle is light and solid. The muzzle device seemed comparable to a bird cage, and I loved the trigger. I could not be happier with my purchase.

    Rifle is solid, and very accurate. The B5 furniture, aftermarket trigger and aftermarket charging handle make this thing above the rest!

    Very impressive AR Rifle

    Posted by K. Taylor on Jan 10th 2023

    I was very impressed with this rifle upon arrival and so was my FFL transfer dealer. The quality is top tier. It’s a rugged rifle yet very light weight and the muzzle brake/flash hider that’s installed is very cool. I installed a Trijicon MRO green dot optic and I’m very pleased with how accurate this rifle is. I’ve turned over many guns in the past but this Faxon Sentry is a KEEPER!
