The FN 15 Guardian is a fully featured 5.56mm AR pattern carbine with a mid-length 16-inch barrel. It’s outfitted with a full-size 15-inch free floating M-LOK compatible handguard. The handguard has 24 M-LOK slots across three different sides. The top pf the handguard has a full-length section of Picatinny rail to mount accessories easily.
Every major component in the new FN 15 Guardian is made to meet the standard military specifications or better. Let’s take Guardian’s bolt, which is made from 9310 steel, for example. The original specification calls for this part to be machined from Carpenter 158 alloy steel. The Guardian uses 9310 steel, which is approximately 7% stronger than Carpenter 158. Furthermore, many other firearms designs, semi-auto or full-auto alike, already incorporate 9310 steel into their schematics. And unlike Carpenter 158, which is a single source and proprietary alloy, 9310 is a standardized tool grade steel. Meaning it is more available and less expensive in the open market, which means that savings are passed down to the consumer.
FN 15 Guardian’s Receivers
The FN 15 Guardian’s receivers are made from the customary 7075-T6 aircraft grade aluminum alloy. The receivers are finished with the standard Type III hardcoat anodizing. The 16-inch barrel is made from 4150 chrome moly vanadium ordnance steel, which is the tried and true choice for ARs. Unlike true “mil-spec” carbines, the FN outfits their Guardian rifles with a mid-length gas tube. It benefits the entire system as whole with the reduction of operating pressures by virtue of its slightly longer length. This means that the shooter gets a rifle with a smoother recoil impulse that’s also less harsh on the action while still maintaining reliability. FN’s carbine has a retail price of $999.
