(Phoenix, Arizona January 2nd, 2019.) We broke barriers and won awards when we released the piston driven .308 Revolution. Now, we are pleased to introduce the Revolution DI (Direct Impingement). By popular demand, you get the same technology, same durability, same features, and same AR-15 size (yes, it is truly an AR-15 sized rifle that shoots .308), but in a smaller direct impingement system.
What makes the Revolution so special? First, it is NOT a small frame AR-10, its smaller! It features many 5.56 parts; such as charging handle, bolt carrier, roller cam pin, buffer, heat-sink barrel nut, and handguard. Those are just the parts that are interchangeable. The barrel extension, bolt assembly, upper and lower receiver are all the exact same size as those found on an AR-15. This is what makes the Revolution Di possible, and puts a .308 AR platform in your hands that feels and handles like your 5.56 AR-15.
The Revolution Di didn’t shed weight by eliminating features. It’s quite the opposite. There is virtually nothing left to upgrade – no matter your shooting style or sport. This is a full-featured battle carbine complete with an ambidextrous billet lower receiver, 9-position adjustable gas block, heat-sink barrel nut, Renegade rail, single stage match grade trigger, triple port muzzle brake, and more.
The original Revolution PD (Piston Driven) weighs in at a paltry 7.35 pounds, turning heads for its incredible lightweight and small stature for a .308. The 308 Revolution DI weighs even less at 6.81 pounds with a 16” barrel, making it ideal for just about any situation you put it in.

This thing seems like a kaboom just waiting to happen. You can only stretch the limits of material science so far.
And the question is how accurate is it? Comparable to JP or LaRue? I wonder about the groups from the piston Revolution. It was not all that great as advertised with POF308 I’ve seen – 2MOA or more with theoretically right ammo.
Accuracy and handling is top notch. The fact they get stuck cases with steel cased ammunition is a no go for me. If all you shoot is brass your golden though, if not keep a spare rod around to bang out the steel cases.
When I fired these rifles, all we shot was steel cases ammo. In fact, that’s what they test with. Could you expand on your experience with POF guns and stuck steel cases?
Just me, but I feel like if we are buying into a $2,000 + rifle probably 3k after optics etc. there is no way I’d cheap out on the ammo. I only shoot Federal 5.56 in my ARs. Its cheap enough, widely accepted as great quality re-loadable brass, and if you mess with silencers/adjustable gas system parts (like this rifle has), there is an argument to be made for shooting the same type of ammo all the time. You don’t wana have to re-tune the gas every range trip because because we are buying bottom of the bin random junk ammo with unreliable powder charges. I’d pick a good ammo (not steel) and stick with it.
If I was buying one of the top end rifles in the production market I’d factor in paying for mid grade ammo, at least. I shot steel case in an old AK over a decade ago, but that gun was less than $400 back then. Some guns like certain types of ammo better. My 226 doesn’t like Win white box, so I feed it federal, my 320 is more tolerant of it, but never does tul ammo go in any of my guns.
Top notch is what? 1MOA? What distance? Do you have any pics of groups shot factory ammo? In my short experience most of semi auto .308s are over advertised. I’d trust only a few and even they have problems. Show me something that weights like a SCAR-H, has 16inch barrel maximum and produces groups smaller than 1MOA consistently so that I can hit human sized target at 800 most of the times and is clean liie a piston gun please. This POF surely looks interesting. Well done if it holds up in terms of reliability, accuracy and durability.
Sir, 1 MOA implies 1″ at 100 y.
The fact that a gun shoots 1 inch at 100yd doesn’t mean it will shoot 8” at 800 even in the best of conditions and solid mounted to a bech rest. The question is practical accuracy.
Sure. To be up front it has occurred with the POF (p308 and revolution, a buddy I shoot with has lots of very cool stuff) and with another brand of piston 308 rifle. No matter how well we clean the rifles (chamber cleaning) after 200 rounds of steel cased (tula or wolf) spent shells start sticking in the chamber. Usually we can use a rod to get them out but on multiple occasions it took oil down the barrel and waiting and then banging to dislodge the stuck cases.
We never have this issue with brass cased ammo and this issue has only arisen in rifles with 308 caliber. Never had this issue with 7.62×39 or 223 steel cased in my piston ARs and it is the only type of ammunition I use in them.
On examination of the stuck casings it is obvious that blowback is making its way around the case in the chamber and after so many rounds this acts like glue.
I do not have a reasonable explanation for this, however I do see SLR rifleworks using their SBR 308 DI ar with steel all the time and they do not appear to have these issues, or it isnt mentioned.
I am also not under the impression that it is the ammunition as per testing in multiple Saiga 308s there are no such issues no matter how many rounds are fired between cleanings.
Could there be a loss between chamber specs with the russian ammo? Possible. Could it be out of spec chambers? Possible. I do not really have an answer but I can tell you it is utterly disappointing to have to ram cases out of $2k plus rifles.
Have you discussed this with POF?
Yes, they told him it must be ammunition related. Even though lots of their torture test videos show them using steel case on FA.
@john you are describing a known problem with shooting that junk ammo, the coatings on the steel cases gumming up the chamber. My question is this, is it worth it? Imagine how hard it is on the rifling of your barrel to always be banging out steel cases with a cleaning rod. I mean, if you guys are just blasting away to be blasting it is understandable why you would continue that practice. If you want accuracy, tight groups, a longer lasting barrel and things along that line, I’d discontinue that practice. How crazy it is to mess up a barrel on a $3K rifle to save a couple bucks on a box of ammo, to me.
On the other hand, I did see a great article or video from lucky gunner about the cost savings of shooting steel cased and you can buy a new barrel. That would assume you can get the same or similar barrel and properly install it, etc. and I’m just not into that. If you dont have the tools or knowledge and have to pay a gun smith then you need to factor all of that into your cost savings estimate of ammo. Best of luck dudes!
I wouldn’t say its really a known problem. As I mentioned in my original post Steel cased is exclusively used in my other ARs one in 7.62×39 (POF that runs like a champ/is very accurate) and 223/5.56 (LMT). My buddy with an lwrc in 223/5.56 and a POF in 7.62×39 also never experiences stuck cases….EVER. I have had zero such issues with these rifles. Which leads me to believe its either an ammunition case dimension issue or a chamber problem. I dismiss your assumption it is due to the case ‘gumming’ up the action. On piston driven ARs the action does not get hot. I can shoot and shoot and shoot and pull the bolt out and hold it in my hand.
It also does not matter if the rifle/chamber is hot or not, it just appears after a certain amount of ammo is fired. The stuck cases begin to happen and do not stop until thorough cleaning is done.
We have done much experimentation with this and have gotten the rifle nice and hot and chambered a round and let is sit until it was cool. Extracts with no problem. The rounds only stick once they are fired.
Also as mentioned previously they always have soot/blow back around the outside of the case that is obviously gluing them in the chamber. This blow back issue also does occur on the above (4) mentioned ARs.
Maybe it is an issue to do with 308 case pressure? We all know that steel doesn’t expand as much as brass does when fired. Maybe the case dimensions of the chamber or ammunition is such that the proper seal is not formed and too much blow back occurs in the chamber which then sticks the cases.
Just my experience and 2 cents.
‘This blow back issue also does occur on the above (4) mentioned ARs’
The above quote should say….
This blow back issue does not occur on the above (4) mentioned ARs’
my apologies
I did not say gumming up the action. I said gumming up the chamber, and that is what is happening. Again, all guns are different, just because some of your ARs, no matter the caliber, likes steel case doesn’t mean, in any way, that this other gun will.
Your glock might like winchester forged, Tul, whatever, that doesn’t mean your CZ shadow will. Different tolerances, made different, whatever. It doesn’t mean there is a problem with the gun just because it won’t run the lowest cost ammo available. A Ferarri may not run good on 87 gasoline, a body builder may not run good only on McDonalds every day I think you get it. Lastly my main concern would be dinging up your rifling all the time to bang out those cases. There are many guys who don’t even put a hard rod into their barrel ever, much less hammer them around in there, frequently. Shoot what you like dudes, but the barrel is crying for decent ammo.
Chamber not action. Agreed. What was it that I said about the steel case getting blow back on the casing in my last response? Of course the chamber is going to get dirty, something is not sized correctly. Be it ammunition or chamber size.
The question here is not your opinion of what kind of ammunition you like to use but why I see FA DI 308 ars eating steel like candy when the gun of the year chokes on steel. But you know the whole ferrari with regular, goshdarnit works for them. Plus there is that little tidbit you overlooked where I went over a plethora of other rifles that eat a mixture of steel and brass or just steel and have zero, nadda, no issues. Things that make the thinking man go hmmmmmmmm. Not just blame it on ‘bad ammo’ which is a manufacturer favorite when they don’t know wtf is wrong with it.
Sorry Sam but you appear to be protecting something instead of actually looking at the issue. You deny there is a problem here and blame it on the ammunition. That is fine. But you have zero proof this is the issue. I was just releasing facts, which you appear not to want to hear as it doesn’t shine something in a good light.
We need more real people in this industry. Not more snake oil salesman, there are more than enough of them.
Also do not worry yourself about the barrel. When it isn’t choking on the steel it will still hit targets at 3 or 400 yards with ease. These rifles don’t have accuracy problems, that is for sure. Even with the, omg, rod down the barrel. BTW it wasn’t even a rod, but the antenna off my chevy blazer.
