Now the upper/barrel and rail.. this has the gas piston as well. Note that the charging guide rod is also the gas piston rod. A very good design that does not waste anything that is not needed, and it's very robust and reliable. Note that the slash cut flash suppressor is designed to reduce recoil barrel rise, as well as not being vented on the underside, so you don't dust storm yourself out when shooting near the ground while prone.
Breach side, has a AR type rotating bolt lugs, but they are totally out there, and easy to clean when this gun is torn down. They supply the right cleaning tools with the gun, but any small tooth brush would work fine, unlike the AR where getting to this stuff can be a real PITA without the right tools/brushes. Also note that small tube, with the white poly clip around it. That is where the empty brass is pushed out of the gun, and ejected out the front of the rifle, just to the right of the gas piston block. (Basicly pushes the brass up under the sight rail.)
Rotating AR style bolt, and the guides for the brass. Note that this is a very high quality forged part, and the machine work on it is first rate.
Another view of the bolt and firing pin. Note the captured spring. You just release the pin, and the bolt comes out for cleaning, much like an AR, but with less crud as there is no gas used here to lock the bolt, just mechanical latches and guides.
This is the two position gas piston port and selector. Nice if your shooting suppressed rounds, or crappy ammo, and with the larger "normal" setting, it makes for less felt recoil with fully loaded NATO spec ammo.
Here I've removed the selector, and you can see the piston crown in the bore.. This has a rod on it that pushes on the charge guide rod that is connected to the bolt. This is the only part that becomes dirty with gas created build up, and FNH provdes the correct sized tool/scraper to clean this with the rifle.
Here I've put the bolt and charge/guide rod back into the gun. That flat end of the rod is what the piston end would push on to unlock the rotating bolt.
Gun with the upper partly slid back into place.. It's like putting a large autoloading pistol back together.. you just slide this into place, and then click the take down button/pin back into place and your done. Note that I've already put the hammer assy. back into the stock, and slipped the butstock pad into place that retains the hammer assy.
It has a Hogue stock, Butler Creek Carbon Fiber bull barrel, and nice 3x40 scope. Nice, light and accurate to any range the .22 is worth shooting at.
