After patiently awaiting these previously announced 20 round NON AR15 FITTING magazines at 35.00 each, I am really impressed!!

All other 5.56 bolt action rifles that can only use AR15 magazines, are completely dependent on our Government with their misinformed laws and the main focus being AR15s, hopefully never AR15 magazines. If by chance they prohibit AR15 magazines, all those bolt action rifles will be in a very awkward place concerning loading cartridges.

By taking into consideration both the magazine and the ribbed mag well design of the Bison, this has resulted in a far better solution than any other bolt action rifle I have handled that solely use AR magazines. It is very obvious much thought went into this unique design of a magazine. The magazine as expected loaded, fed, and cycled smoothly. The material chosen seems very robust, being able to use different calibres in the magazine as you change barrels or swap between different MRX platforms is genius.

So to sum it up, BCL has really thought out this platform very well, being the only rifle I know of that has the option to use AR and proprietary magazines, never mind cool looking 20 rounders! The option to have two magazines holding 40 rounds as opposed to numerous five and ten round magazines in the field is a no brainer.

Really loving this platform, and it's well thought out long term options. It did take some time to find a load it likes but this little rifle has quickly become our favorite plinker. I was originally looking at a new metal stock for my .223 bolt action rifle, but it was actually less for the Bison than the tactical stock I was considering, can never have too many fun handy bolt actions.

Saw a very nice all metal compact bolt action with a sliding stock at the gun show that looked incredible, but it was $3000.00 and did not have a 20 round magazine option. :(

I see many other designs of firearms that will incorporate these magazines in the future, it is obvious BCL are positioning themselves for the long haul.

Well done BCL!

Nice write up and pics.
I agree with your talking points and came to similar decisions re my Bison/mags purchase(s).
 
Im at the point where i am willing to buy mags without owning the rifle. It is in fact not illegal to modify a gun to fit a magazine after all lol. Could see some interesting mag-well adaptations soon
 
I was thinking they looked a bit long for my liking but it looks not so bad in your photo.

If I hadn't just bought some short ar mags for mine is probably pick those up instead to see how they did.
 
If you are thinking these might work in a typical magwell set up for Stanag mags, you aren't going to be firing up a 3 printer, you'll need a milling machine for further broaching... and mods to the hold open device if your firearm is so equipped.
 
How many 7.62x39 rounds will fit in one of these?
The steel mag i got with my rifle, the mag is overcrimped and the third round jams because the mag spring binds up
why do they have to crimp the mags just put a damn pin in them
My AR15 mags work fine but they only hold 3 rounds of 7.62x39 lol
 
The AR 15 mags I tried fed fine but only 3 round capacity
I'll just buy one and see if its any good, if not then I guess i will have to get a 223 rifle lol
 
Well I got the mag and the package says multi caliber?
Anyway for those with the 7.62x39 Bison the mag will hold 13 rounds but will not feed if you have more then 9 in the mag
The first round feeds but the second one gets pushed down tip first in the mag causing a jam, the mag spring feels a bit weak on it so not sure if that is causing it or not
I found 8 rounds in the mag seem to feed the best
Not a total loss as 8 rounds is still better then 5 lol
 
I think it's time to tinker with some magwells...

3D printer warming up...

Going to test this out next week…
