Long range AK Tech Specs
Getting a ton of questions on the AK Sniper, I want to give y'all a run down on the build.
First we started with a Saiga .308, it was mentioned numerous times, as well as when we chose the off the shelf match ammo and loaded up hand loads for it on camera, I guess it didn't make the cut, details often don't make it in. And whomever would even think a X39 round is capable of that range is probably not a buyer anyway....
We used a stainless Kreiger 1:10 34" blank, it was chambered with an obermeyer match chamber for Reliable feeding and proper throat for the 168 and 175 grain loads and turned down to ~1" and cut at 24".
The gas system was cut as short as possible and uses a Micro Galil piston, the gas tube is a galil piece that was cut down and integrated into the RSB so it would free float and not touch the FGB.
The FGB is a fully new fabricated unit so the gas piston would not touch.
The Barrel was floated and bedded using a block that was integrated and pressed into and onto both the Trunnion and Receiver (Slips under and past the front trunnion for quite a ways, almost to the mag hole) the free float tube was pressed over that block and screwed to the receiver and Bedding block.
The Barrel was head spaced tight after the bolt locking lugs, bolt face, Trunnion and Barrel face was all parallel ground.
The FCG started as an Off the shelf unit which was redesigned and the sear re-profiled to have a neutral and shorter engagement. It was also setup with adjustable pre-travel and over travel stops. The hammer was lightened and the Heaviest hammer spring I could find was used to bring the lock time down (I think it was an FPK).
The Carrier was fitted to the receiver as tightly as possible and smoothed to ensure function, the recoil spring was a brand new Galil Telescoping unit with a new rear over travel stop in place of the .308 version.
The receiver was boxed for stiffening at the rear with an extra heavy weld-on plate and fitted with a PRS stock.
I would like to develop a set of stiffening rails for the whole receiver but the trunnion and bolt lock up tight as hell.
I think that was about it as far as high points, there was a lot of detail stuff done that only shows up as the guns are built.
The First group shown on TV was actually a 5 round group at 100 yards with one as a flyer (new trigger for the shooter), the 4 were in the one hole to the lower right (about .2 MOA) .After that I guess it is kind of uninteresting for TV to see the groups naturally spread as the distance increased... It's hard to beat Shooting through a windshield ,a back glass and popping a bad guy in the neck and hitting an 8"X10" baggy of SureShot tapped to a propane cylinder right behind him for a demonstration of it's capability. We are not on the Military channel guys, little bitty holes punched in paper at 100,500,800 and 1000 yards are not interesting to most of the world, I am surprised that any of the sight in groups even made it in!
