Look, the 5.7x28mm round is the real star here. It’s a small, fast projectile that shoots incredibly flat and has almost no felt recoil—I’ve put a few hundred rounds of Federal American Eagle through my own 5.7 platform, and the follow-up shot speed is genuinely impressive. The PWA AR5.7 builds that experience into the most ubiquitous rifle platform in America. The rifle itself is built on a standard AR-15 lower receiver, which means the fire control group, pistol grip, and stock are all familiar territory. The upper is where the magic happens, designed specifically to handle the unique feeding and chambering of the bottlenecked 5.7 cartridge. It accepts FN-style magazines, which are plentiful and have a proven track record. With an overall length around 35 inches and a weight likely under 7 pounds, it’s a handy, quick-pointing rifle.
Who This Rifle Is For
This is for the shooter who wants something different from the sea of .223/5.56 ARs but doesn’t want to learn a completely new manual of arms. It’s a fantastic choice for introducing new shooters due to the negligible recoil, or for experienced hands who want a lightweight, fast-handling rifle for prairie dogs or ringing steel. If you’re bored with your current plinking routine and want a cartridge that feels like a .22 Magnum on steroids, this is your ticket.
Pros & Cons
Pros: The low recoil makes it an absolute joy to shoot rapidly and accurately. Ammunition, while not as cheap as .223, has become much more available and affordable from brands like Federal and Fiocchi. It’s a complete rifle—you don’t need to source a special lower or buffer system. The compatibility with common AR parts (grip, stock, trigger) means you can personalize it easily.
Cons: 5.7x28mm ammo is still more expensive per round than steel-case .223. Magazine options are specific to the FN pattern, though they are common. Ballistic performance on larger game is limited, so it’s not a deer rifle. That said, for its intended roles, it excels.
Frequently Asked Questions
Q: What magazines does it use?
A: It uses magazines compatible with the FN P90 and PS90. These are readily available from several manufacturers in various capacities.
Q: Is the 5.7x28mm round effective for self-defense?
A: With modern defensive loads like the FN SS197SR or Federal American Eagle, the 5.7x28mm offers excellent penetration against barriers and soft armor, with low risk of over-penetration in drywall. Its low recoil aids in shot placement under stress.
Q: Can I use my standard AR-15 .223/5.56 magazines with this upper?
A: No, you cannot. The 5.7x28mm cartridge is a completely different shape and size, requiring a dedicated upper receiver and specific magazines designed for its unique feed geometry. This rifle is a complete, dedicated system.
