I would like to get a list going for all available calibers as long as they work with the standard AR15 lower reciever not AR10 lowers. I know the basics but would like to know all of the wildcat calibers. Please only list ones that are in production or will come into production not one-off prototypes made for the fun of it. If something is obscure and only available from 1 or so manufactures please provide links. I will update in my original post. Thanks guys
I'll start, but someone needs to fill in the holes
17 Mach IV
7x40 (old 3 gun round)
6.5 x 33 (6.5 Whisper)
6 - 6.8
223 - 6.8 (various names)
17 Mach2 or whatever it is called
5.45 x 39
40 X (40-50AE)
502 TS (rebated 50AE)
32 ACP (Tromix prototype)
6.5 BR-R (rebated rim)
That should do for now ...
Nice list...just one minor correction.
awesome that is exactly what I am looking for
Man, it's gonna take years to collect the whole set!
isn't there a 50bmg upper that uses a regular ar lower? it is bolt action but not a 1 off if i remember correctly...
There are several of them, I have two myself.
I was eliminating those as they do not use the standard AR mag well for feeding. If you go that route you can include
22LR - American 180 style
5.7 x 28 using P90 mags
A pile of others that fit the 50 BMG mags ...
Are you talking about the rhineland arms project? I was under the impression that was a no go.
There was discussion about the AR57 platform.
In that thread, there's a link (shown below) to the website that is going to sell them.
Is the 357 Automag the same as a 357 Mag pistol round ? if it is
please say where can I get one !!
Need to add:
The ejection port needs enlarging & the mag followers need to be modified. That & there is no commercial ammo available. This round should be able to duplicate 260 Remington ballistics.
Nope. 357 AutoMag is (more or less) a .308 Win case cut short and necked to .357. Recall (or Google depending on your age) Dirty Harry using the 44 AutoMag in "Sudden Impact". This same round necked down to .357 gives the .357 AMP (Auto Mag Pistol).
VERY different from the .357 Magnum commonly found in revolvers and other firearms.
so you can use a standard ar15 lower receiver with differnt calibers? im new to AR's and just bought 2 double star receivers. waiting to get them now!!
