Silky Smooth
This is the 4th Defiance action for me from Altus. This one is the stainless SA 308 bolt face. The action is super smooth like it’s on ball bearings! I had Josh and Altus spin up a 28” 1.25” Bartlein Barrel for in 6BR. All I can say is WOW! The action not only beautiful in appearance, but in function as well! Josh and team at Altus always make buying from them a super awesome experience! Thanks guys!

Super smooth action!
I love the attention to details and the finish is super nice on both the receiver and the bolt! Excellent craftsmanship and very robust! Looking forward to getting one in Nitride next.

TOP TIER QUALITY
I purchased this action a couple of weeks ago. This is my first Defiance action. I also have an Impact 737r and Bighorn TL3. This Rcukus is right on par with them, maybe even runs just a tad smoother. All three are TOP quality and can't be beat. Buy this action with confidence from Altus. I ordered a "prefit shouldered" barrel from Hawk Hill without them even measuring the Ruckus, and it headspaced perfectly. You won't go wrong with this Ruckus, Impact, or Bighorn (Zermatt).

Ruckus SA Nitride, Std BF
Received the action 2 days from time of shipment. Was ahead of the projected date, which was a pleasant surprise. Bolt is silky smooth and timed very well from the box to my TT Diamond 2 Stage. The action is with my smith getting a barrel spun and dimensions recorded. While these actions are “guaranteed headspace” they do vary by a couple “thou”. I had the barrel from my other Defiance action spun on to check, and this one is about .002” longer. Not a complaint, but would have been amazing if they were within .001”. Buy with confidence, both from Altus and Defiance. I have needed to use Defiance CS in the past and had the repair performed and back in my hands (AL > MT > AL) in less than 72 hours from dropping it off at the parcel carrier. I challenge anyone to beat that kind of support.
