Does anybody know of an assault rifle that can use different caliber bullets? If there is, what is it?

Answer 1

A standard ar-15 lower receiver can be changed over to fire other calibers by simply changing out the upper and using a different magazine. It can be quickly changed from .223 to .45acp, 9mm , and even a 50bmg upper!!
As for one weapon that will fire different calibers without making any changes, I can't think of a one.

Answer 2

For starters, the AK-47 shoots the 7.62x39 which is a big caliber, however it's power level is pretty similar to the 5.56x45 NATO and the 5.45x39 Warsaw Pact. that is a basic characteristic of an assault rifle, that it fires an intermediate class cartridge (something between the power of a true rifle round and the power of a pistol round) Guns that are similar to assault rifles but fire full power rifle cartridges are called 'Battle Rifles' The AR-10 you mentioned is one, the M1A (civilian version of the M-14) is another, same withe the FN-FAL and the H&K G-3 (or it's predecessor, the CETME ) However, there is also a trend in creating AR-15s that fire larger caliber specialty rounds. Check out the 6.8 SPC and 6.5 Grendel, they are the about half way between the 5.56x45mm and the 7.62x51mm there is also the 458 SOCOM and the 500 Beowulf, which are basically the same thing but with really big wide bullets, meaning enhanced stopping power at close range but not a ton of long range ability

Answer 3

Caliber?

Quit using the term "Assault Rifle".. Use semi-auto military styled firearm instead. We have to deprogram people from using the anti-gun media's favorite term for a semi-auto firearm.


I have a buddy that has a retrofit kit to shoot 22 long rifle in his AR 15, normally a .223.

As randy said you can reconfigure an AR for a lot of different potential uses. It is not as easy as just slipping in a different mag, changing the upper requires some brains.

Answer 4

There is a lot of diffrent uppers you can pun on an AR lower. from 50 beauwolf to 22 LR. There is one rifle that I can think of I think it is called a crossfire that has a 223 mounted under a 12ga. I wouldnt call it practicle for hunting though. Keep in mind that a some states do not allow 223 to be used for deer hunting due to its lighter bullets. In wa you cant use under a 100 grain bullet. You may want to check that.

Answer 5

a .308 lower for an ar 15 can convert a .308 rifle with a simple barrel and upper swap can become a variety of diffrent rifles such as .260 rem, .243 win, 7-08mm, or any other cartridge based off of a .308 cartridge. hope that helps or makes sense

Answer 6

Same rifle that can use different caliber bullets? Different cartridge? Self loader? without barrel change? Not offhand for all conditions. For a single shot I have seen the old BSA Martini Cadet shoot 32-20, M1carbine, .32 pistol cartridge. Bolt action K98 Mausers report in african wars to have been loaded and fired 7.62 NATO, 7mm Mauser, 7.65 mauser ammo these cartridges had same base diameter and roughly same case diameter, fireing the small bullets from 8mm barrel wasn't accurate but the troops were not good shots to begin with, they got a bullet traveling somewhere close to opposition to make him duck. Selfloaders- M14s and FN-FALs sometimes known to single fir .300 Savage, M16s also fired .222- turns them into single shots. Interchangeing barrels can give a receiver/trigger group another caliber. AR15/M16 lowers sometimes get a different upper assemble and barrel, the variations include 9mm pistol, .222, a 6mm PPC, 6.8mm . these cartridges have same basic case base diameter. Another interchange barrel is a Mauser model 66-not sure of model number- refers to commercial 1960s design as a takedown model- was sold in some countries with extra barrels, legal situation in market country restricted number of guns allowed, receiver and action was counted as gun and extra barrels included didn't count as extra gun. Similar situation exists for a h&K pistol with .22 barrel /.32 barrel or the 9mm and extra barrel in 7.62x23 Legally same gun but capable of firing different ammo with barrel change. Rheinmetal had a G3/HK94 type with quick change barrels available 9mm, 5.56x45 and 7.62x39. This also had magazine adapter and bolt buffer mass for different cartridges. M3 submachine gun had 9mm kit for basic receiver/trigger group- was a 9mm barrel, bolt, and magazine adapter with couple other small parts. Vietnamese made a kit to convert French Hotchkiss submachine gun from 9mm to 7.62 depending on ammo supply anticipated. This should keep you occupied figureing out what to get, maybe NEF 2/3 barrel set.

Answer 7

No. Realy the only gun that can use more than one caliber safely!!! Is a some 22 rifles can shoot longs and shorts. And all 357mags can shoot 38's. Thats it anything else must be rechambered.

Answer 8

yea Halo 3 Assault Rifle!

Answer 9

Some AR-15s take what you call a wildcat round. It chambers both .223 and 5.56 ammo. But its basically the same thing so its not what I would call a, 'completely different caliber'.

Answer 10

Depends on what you mean by different. If you mean like different than .223, then yes. If you mean like one gun firing more than one type of shell with no modifications, then I would suspect not but it is possible.
