Our industry is blessed with some outstanding custom actions to choose from.
Several makers offer innovation and quality above and beyond the rest of the pack. With so much quality competition, I wanted to give kudos to Defiance Machine for what they have been delivering.

I have sourced certain actions from Defiance since 2007.

They have been the sole source of my SENTINEL and LongSword actions since 2014. I have been happy with them and have a ton of confidence with the rifles going out the door.
I have likely become a little spoiled with the consistency as it gets mixed into all of the other daily things I work through.

This week I have been documenting dimensions and headspace measurements from a group of actions in preparation to shipping their bolts, cocking pieces, extractors and firing pins out for DLC. This allows me to proceed with doing all the barrel breech work for each receiver even while the bolts are out for coating.

What caught my attention yesterday and tonight was the crazy consistency of the measurements across this group of 11 short actions and 4 long actions. Using my particular methods and tools, I documented 14 out of the 15 total actions being inside a 0.0005” headspace range.

That is half of one thousandth inch. The one action that was outside that limit was only another half thousandth long. So even counting the “bad” one (sarcasm), all fell within a one thousandth of an inch range.

At worse, I was previously seeing everything across the board falling into 0.0015” H.S. range which is still very good but this latest group is exceptional.

I am getting the features I need from Defiance to suit my niche and most certainly getting the quality and CONSISTENCY that makes it a wee bit easier for me to deliver excellent rifles.


Thank you Glen, Norm, Mike and the rest of the crew at Defiance for putting up with my questions and worries.

Curious as to why you don't order them already DLC coated from defiance since its offered now?

I have a coated one that is very nice but it was done after the fact along with a little other work and its extremely nice. I haven't messed much with the factory DLC ones though in comparison.

I absolutely would not do that.

Almost 100% of my customers are looking for CeraKote exteriors that produce a matte, non-reflective finish that is very corrosion resistant. DLC would not provide the properties needed for me.

Many of my customers also need asset numbers, team numbers, agency name, etc marked into the surface when shipped. If I had Defiance DLC all of my actions prior to me receiving them, I would be blasting most of it right back off in prep for other coating.

I can finish marking all components of the actions received and ship to IonBond in batches very economically and with great turn around. I can also spec exactly what surface prep and DLC version I need. For instance, all of my bolt bodies are aluminum oxide prepped for a matte finish that has more texture while still being very hard.

If I were knocking out competition guns and trying to keep the cost, labor and delivery time short I would have no issue getting them delivered completely processed already. That is not my market so that is not what I order.

That makes sense. I know prep work can make a world of difference when coating.
 
I just got a Defiance action and to my knowledge they only offered a nitride finish. Both the bolt and the receiver were done.

They do bare stainless, nitride and DLC (ionbond), and maybe others.

One of the great thing about Defiance actions is they offer lots of options - way more then most any other action manufacturer.
 
I purchased one of their BadRock rifles in .308 last year and I can’t say I’ve ever been happier with a purchase. Stellar price for what I got too. God bless those guys. Heard about them and gave them a call to ask questions and after I thoroughly interrogated the person on the other end, I bought one.
 
Why dont we see shouldered prefits like the origin has if they are that close?

You might want to pay close attention to some new offerings by PROOF Research coming soon, and some new announcements coming from Defiance Machine here shortly. According to their Facebook/Instagram Story they just posted today, it looks like one of those announcements is coming tomorrow.

i agree , i sold my tenacity right after i bought it and ordered an impact for that exact reason

Impact makes great actions, and we love Wade and Tate. No one will argue that. That said, you're comparing one action that retails at $1390 verses another that retails at $885. An additional bolt for an Impact is $450, for the Tenacity $275. Not really an apples to oranges comparison. And just wait for our Christmas announcement...

One reason might be because variants have been in production for a while. Even though the HS was pretty consistent across the board some of the older ones may not fall within acceptable ranges to be considered universal candidates for prefit barrels.

With new machines on line and more focus being made toward pre-fit barrels, the newer generations from them will likely be designated as viable for that option.

I have seen exactly how off the scale individual customers can be with their expectations and lack of understanding what is needed for consistency at 50,000 psi.

Accordingly, I would not want to be counting on 100% of the market paying attention to serial number ranges and/or model numbers.

With their new info release about the Tenacity, you are likely seeing them pushing something out there that can be better defined and controlled for the pre-fit market.

All of the above is strictly my opinion and should not be considered as information coming from Defiance Machine. They are big boys and can address your questions 100 times better than I.

PRO TIP: Questions like these are better directed straight to the manufacturer rather than an internet forum with 10s of thousands of experts not associated with Defiance Machine.

makes a lot of sense

Once a gunsmith has seen your action the specs of your action can be saved and your gunsmith from there on forward can build you "prefits". My gunsmiths do anyways, I order a barrel to my specs, they spin it up and send it to my house.

Sounds like Defiance actions going forward prefits should be more readily available, good move for Defiance.

Terry is pretty spot on. We'll have an announcement this Christmas, and we think a lot of people are going to be very happy.

Love my Deviant Tactical actions. I have NEVER had a single jam or failure to feed or failure to extract on both of my rifles. Had them for a few years now. They run perfect. This is with both AICS and AW mags. I have no need for any of the other novel features other companies offer. While some of those things seem cool, I don't see how they improve something that already works 100% of the time. Thanks, Defiance.
