With the increasing amount of AR15ification (ey-arr-fifteenification) of the worlds rifles (Sako is making the M23 for the Finns and Swedes, Beretta unveiled the NARP, etc.) it's refreshing to see a different pattern of rifle coming to the market.
The long duration of the AR group has encouraged problem areas to be refined, the modular quality encouraged small improvement and specialization. The separate upper permits piston designs for intense users
And when those "intense users" either need the rifle to be light, as accurate as possible, or both, inevitably they always go back to the original pseudo-DI internal piston design.
KAR-21 was a lot of fun to shoot both at Finnish Brutality 2023, and at the range. Hats off to Ensio for developing something new...looking forward to owning one!
Loving this content. Not selling, not pushing, just explaining. Excellent. I live in the town where Uintah Precision makes bolt action uppers to pin onto AR lowers. They had similar issues with making “not” AR stuff fit an AR world. The thing they struggled with was hammer follow, some AR triggers would stay cocked, some wouldn’t.
Looks fantastic. In engineering it's often something unexpected like that causing the issue. Soon as I win a lottery I'll get one when they get in the USA.
Thanks for very nerdy video, more this kind of stuff please! It´s a cool gun, balances well what I had chance to play with it in Finnish Brutality. In 223 is kind of a heavier side compared to AR´s but in 308 it feels great gun. Might get one someday. But if possible, I´d like to have a folding stock. Would be relatively easy to do in a design like that. And adding 6.5 CM for the caliber list would be nice extra. I think this rifle makes more sence in 308/6.5 CM combo than a 308/223.
Ah, so the accuracy issue was functionally the same two group issue as is in early Kalashnikov type rifles, mostly fixed in them by changing the shape of the underside of the bolt carrier.
Wow! One would think that the locking of the bolt would ensure that it was exactly perpendicular to the bore, then that the barrel itself would ensure consistent bullet flight, but there's no arguing with the results...GREAT detective work!
@@thebeardprevails5246 If i understood right when you guys had those assault rifle bans finnish valmets werent included on that list. I wont deny this looks cool. Bit expensive but im still keeping this at possible candinate when looking for .308 variant for semi-auto.
I like the KAR-21 rifle the design changes are well thought out and have rectified any issues obviously. The piston rings on the gas piston are a great idea with a few advantages such as better gas sealing a little more clearance between the piston and bore for better reliability and less heat transfer past the rings. It's not every day a totally new rifle design comes along I'm sure a telescoping folding stock can also be designed and fitted which will give the rifle two buttstock options and add to the practical modularity of the rifle. A thumbs up from me with the monolithic upper allowing for an increase in accuracy and strength because of the zero flex nature of a one piece design with the overall heavy duty nature of the rifle allowing the .308 round to be used successfully even though the recoil is considerable. If the 3.7KG weight for the gun is the maximum in both 308 and 223 configuration then it covers all the bases with the calibre conversion system from .308 to .223 the icing on the cake. As a reference point the H&K 417 with the same length barrel weighs over 4KG from the factory. A very well thought out rifle with a bright future ahead with some really innovative features. If they can get the rifle to run full-automatic in both NATO military calibres and run reliably they will have a winner. Military contacts are also a possibility if enough successful testing is done with the manufacturing perfected and the price reasonable. And congratulations to Finland for having joined NATO it means new service rifles will be needed fairly soon in NATO calibres and this rifle fit's the criteria nicely. It's nice to see something that works extremely well and is not based on the AR-15 rifle as was mentioned in the video. I can understand why the English dude was so proud of his contribution considering they have lost the art of small arms design with no serious contributions since the nineteen fifties. The rifle definitely gets my stamp of approval and could end up the Patria AMV of rifles. 😎🇦🇺👍
Pretty sure Ensio would be more than happy to supply those in states. But taking account how those are priced around 3800 e in Finland. Shipment, documentation and proofing will make a sure that even in states those will be damn expensive. Definelty not something which could became anything but niche product but isnt that pretty much a deal with rare european made guns in states. Someone is getting it and doing fun shit at range and then there are multiple guys wanting that same rare piece.
@@BlokeontheRange I forgot guns doesnt need to be proofed in states. Everything what comes to state side to here needs to be cip proofed. And im pretty sure that if you want to sell gun in europe it had to have cip proof markings.
@@BlokeontheRange Then i apologise my lack of proper knowledge about that subject. I kind of assumed that to be more global thing in europe. Like always so many variants about how things work in different countries. It is hard to keep track.
I assume that this design shares the AK anti pre-engagement feature? If that is the case then what's being use to cause the first rotation needed for the bolt to lock? Like how in newer AK a bump rivet is used.
You have a really good point. You must know much more about firearms mechanics than average person. Anti pre-engagement feature has been implemented little bit differently in KAR-21 than AK because of small angle of rotation of the bolt. Best wishes - designer.
B&T's mbt stock would be a nice addition to the rifle. If ensio releases a 7.62x39 conversion kit, it has to come with a kar16 style magwell. The design is so much better than the various ak mag fed ar. Wish them all the best so that I can buy one in 20 years time.
I would have never ever thought that the bolt face could change the impact of the bullet!!! 🤷🏼 How in the hell. Unless there is enough pressure that it is changing the direction of the muzzle because of it. Because it’s not pointing the bullet in different directions in the barrel. That would be stupid and dangerous. So it has to be that it is walking the whole rear of the barrel right and left. Crazy. That barrel needs mounted so secure that even pushing on the end of the muzzle won’t affect the accuracy. It should be rock solid if possible. They need to make this more rigid. Also I worry about those Allen screws coming lose. They need to be keyed and retained somehow with an integrated tool. Also I’d like to see an adapter that removes the butt stock to fire without it for CQB.
Couple things, personally I would change or at least offer as an optional part 1: Folding stock, doesnt make a whole lot of sense to not have that feature with a design like this. 2: Fold away charging handle, having a big easy to grab handle is nice , but as I have encountered with rifles like my X95, they are easy to bump and catch on gear. 3: possibly some QD points built into the receiver, or if it comes with an mlok qd socket that would be nice, but that big stock plate in the back would be a nice spot to have a couple QD sockets on either side. I know the stock has QD sockets, but again, with a rifle that should have a folding stock in my personal preference I would rather have the QD sockets on the receiver.
You have to ask yourself what the end game is when so many similar products already exist. Is this better because it's lighter stronger more accurate cheaper etc ...best way to test this is hand a few to a bunch of new recruits and see if they survive. I am not against new products and I hope this does well. What does the hive mind think of the new knights armament for the new British rangers ?
5.56/7.62x51 is the main design goal, but have they explored anything like 7.62x39 or 5.45 (even as a distant "would be nice to be possible")? I presume .300 blk is doable, just not worth mentioning due to how converting from 5.56 is possible on most platforms.
@@BlokeontheRange Needs a FAL style charging handle - even the Americans have now finally seen the light :) Otherwise it looks great, trust the Finns to make a cool rifle.

this is just a ACR/MSBS/XCR/MCX/Bren2/SCAR copycat though too which is the next generation of the "ACR-ification"

If that could be put together with an 18.6"+ barrel, there'd be a market for it in Canada as well for sure.
Until the liberals ban it, leaving everyone to pay for it
My understanding .223 is offered only in 16 inch barrel. .
308 is offerered in 16 or 20 inch barrel.

Question:
Since it uses AK-style bolt carrier, what stops the bolt from rotating when it is moving forward?
