The AR57 Is An Excellent High-capacity Yet Affordable Alternative For Self-defense and Varmint Hunting.
The AR57 (also known as the AR Five Seven) upper receiver for the AR-15 has two claims to fame: a 50-shot capacity and downward ejection for ambidextrous operation. Operating by simple blowback, this upper is available in 6-inch pistol and 16-inch rifle versions, with the latter being reviewed here.
Manufactured by the eponymous AR57 LLC, and chambered in 5.7x28mm, this upper is less powerful than the standard 5.56mm version, but it has certain tangible advantages, including reduced muzzle blast, a high practical rate of fire, nonexistent recoil, and the ability to use folding stocks. Since the buffer is located within the receiver, folding stocks may also be used for compact storage or carry.
To load, place the baseplate of a standard FN P90 magazine into the recess on the front of the upper, then press the feed lip side down on the catch located above and slightly back of the bolt. To charge, pull on the right-side nonreciprocating handle and release. The right-side charging hand placement makes it accessible for operation by the strong hand. Since it only has to be operated once every 50 shots, the time penalty for moving the hand off the pistol grip isn’t too great. Read the rest of the gun review here.
On my list of “To Get”. Great little round.
If you can afford the ammo.
I shot one a few weeks back in the original Belgian configuration (not AR).
Feels like a 22.
If you can find the ammo.
I don’t see the big advantage of buying a gun in that caliber. It’s not like 5.56 is a powerhouse, but at least it’s widely available and relatively cheap. I wouldn’t want something less powerful for self-defense. I’ll stick with 7.62x39 myself.
I take it the reviewer doesnt have to buy his own ammo. 5.7x28 whew... Expensivo.

And that alone is the kiss of death. Add to that the "less powerful" phrase, and why not just get a 22LR?

Looks fun to shoot, but I don’t see it for much beyond that.
I’ll stick with AR & AK, which seems to cover the carbine niche for me.
PSA has the ammo on sale for $17.99 right now. Even then 36 cents a round seems a little pricey for something that lightweight.
I have the pistol, and really like it.
What I’d really like to go along with the pistol, is a bolt action rifle. Savage started to make one, then dropped the idea.
Or what would be absolutely perfect for my wants, a slightly scaled up Ruger 10-22 but that uses the pistol mags, in that round.
BUT.. I will say that a P90 is my favorite "backup" in Rainbow Six Vegas 2. And even there it has crap penetration.
I would not trade my Springfield Armory M1A National Match (Loaded) for a 5.7. Also an AK for backup.
The ammo is not that bad. Palmetto State Emory has FN 5.7 ammo for 17.99 a box.
Just a little bit of info on this caliber, the Secret Service uses the FN P90 in 5.7 to protect tbe President. The UK guards who guard the Queen of England use the FiveseveN pistol chambered in 5.7 to protect the queen. That speaks volumes about this round.
My next spare upper (when can I afford it) will be in 300 blkout...I would have got an AR in .308 if the budget allowed, but I had to settle for 5.56.
t’s a rifle round fired from a pistol.
It easily defeats any soft body armor up to level IIIA with the right ammunition. (which is legal to buy, possess, and carry)
It basically renders soft body armor obsolete and useless.
It has a range 3-5x what a typical legacy caliber pistol has (depending on skill level)
It hits velocities up to 2600fps from a PISTOL with some ammunition, which creates a rifle like hydro-static shock bubble upon impact with soft tissue.
It holds 20rds of ammunition, or 30rds of ammunition with an extended clip that only protrudes about 1 1/2” from the pistol grip.
It has virtually no recoil whatsoever. Follow up shots are extremely fast, and very accurate.
It’s only competitor at this time is the HK 4.6x30mm, used by the US Navy SEALs in the HK MP7 platform.

.308 is king; I was limited financially and had to settle for 5.56; I’ll upgrade to 300 blk when I’m able
Yeah. Color me skeptical.
