Application / Regulation advice Question about the henry supreme
I know ARs are usually easily convertible from 5.56 to .300blk but would this be. I will probably buy a 5.56 because of ammo prices but it would be nice to be able to hunt deer with it too. I see 450$ .300blk barrels that would be a nice combo gun. Can someone confirm or disprove my theory please?

Hey man, I had the same dilemma. I strongly recommend getting a 5.56 lever (what I got) and getting a .308 bolty for hunting. The 300 aac conversion is tough and if you don’t know what you’re doing, don’t do it.

Well I hace many other rifles I can hunt with. Just thought it might be cool to get a .300blk to hunt deer woth it since we can't in my province. Did you get much infos on the conversion? Is it just the barrel that is hard to remove?

For sure it would be. It’s nice that it’s a shorter barrel as well which is why I see the appeal to hunt with 300. However, you will kick yourself due to ammo availability. And getting the 5.56 just to convert the barrel to 300 is a bit of a useless venture when you can just buy the gun in 300. The next thing that I’m going to say about it is, the 300 is cool as fuck when running as suppressor on it; us being in Canada makes it illegal to do so. My cousin who lives in NH got one. I had the opportunity to try it out when I went down over the holidays and running this gun with a suppressor is a dream. All I’m saying is, if you’re going to get it in 300blackout expect to pay a heck of a lot more for ammo, you cannot use a suppressor on it (which defeats the purpose in my opinion), and barrel conversion is a waste of time. However, great choice to hunt with due to barrel length. And in QC you are meeting the caliber requirements for every hunt from varmint to large game.
I still say, get the 5.56 cause this gun is an awesome paper shredder and varmint gun. For reference here’s the website I found with barrels for sale specifically for this rifle.

OP, don’t listen to this Switching the barrels is as easy as removing the barrel nut and barrel and throwing on the 300 blk barrel. If you have an afrernarket handguard like a Ranger point pewview just toss on a bcm kmr barrel nut and it’ll all look proper.

Pretty sure it’s a bespoke barrel/extension, but it uses an AR bolt. So off the shelf swaps are probably out of the question unfortunately. Maybe you could order a barrel from Henry as a replacement though?
Also .223 is legal to hunt deer in some provinces, though I never have

u/zaphodbssecondhead May 02 '26
It’s not bespoke. It’s an AR barrel with AR barrel nut thread on the receiver

.223 is not legal in quebec unfortunately. But I saw those barrels and was wondering it just cjanging the barrel everything would work. https://line49rifle.com/barrels/l49r-henry-supreme-barrels/line49-henry-supreme-conversion-barrel-13-7-300blk-mwmatch-mod2-cerakote-black.html

I’m 90% sure that won’t work sadly, I looked into it a while back but don’t remember

My understanding of the rifle is that the barrel on these guns attaches to the receiver essentially the same as an AR15 barrel. They just use a proprietary barrel nut. Red Deer shooting centre is selling Henry supreme rifles that they have swapped the barrels on. Their manufacturing company, Shield Rifle works, developed a method of removing the barrel. They then installed an AR15 barrel without a gas hole onto it and secured it using a BCM kmr handguard barrel nut. Once you have the factory barrel removed I guess its the same as removing the barrel from any AR15 at that point so swapping to . 300 blackout should be a simple case of swapping the barrel as there's no gas system and .300 blackout uses the same bolt as 5.56.

I don't think it's a hot swappable option. They come in both, probably best to just buy the one you want and stick with it.
I get wanting to save on ammo but thats $450 USD for an extra barrel? $6-700 CAD? That's a lot of ammo before you start to see a return on that even if it was a quick swap.
If you want .300blk just get it in .300blk IMO

u/SpinachStunning5547 May 03 '26
Well I want .223 because I really enjoy the caliber and it is cheap to shoot a lot of rounds. 700$ in ammo is quickly gone in .300blk. I want the .300 to be able to hunt deer in Quebec with it!

I got one in 300 and went deep down the rabbit hole this is where you want to go for such things https://line49rifle.com/

u/SpinachStunning5547 May 08 '26
You mean sending the rifle to them? Is so sending it in montana seem like a complicated thing no?

u/Professional_Fig_195 May 09 '26
I’ve also heard they are difficult to get off “haven’t tried” but yea I think they might just sell you the parts if your comfortable with the work. From what I understand once your swapped you should be able to swap amongst most standard barrels at that point… * side note: that’s all pretty pricey I plan to just put in the FREE paperwork and send mine out to get chopped down to 9” at under $200 and wait to hear peoples experiences with this route

u/Professional_Fig_195 May 09 '26
Also worth looking into if your going “custom build” routes I’ve seen a couple Henry long rangers out there converted to 8.6 blackouts……” heavy breathing” ….. my ammo budget just isn’t in the 8.6 game yet lol

u/SpinachStunning5547 May 09 '26
For the price of export/imports + parts + work. I think it would be cheaper to just buy a second one!

Apparently barrels are really hard to remove on this one.
