The roller-delayed blowback system is not complex in general, but it does require a very specific manual of arms. It is simple and universal in technique, but it has to be done the right way in order to be fluid. Now, you may never get as fast with it as you would with other weapons that have bolts that lock back on the last shot, but you will be smooth and be able to do it naturally without having to look at your gun while operating it. Practice and really forcing the rifle around is the best way to go, in my experience. ROLLER-DELAYED, NOT ROLLER-LOCKED The roller-delayed blowback system is not as complex as a gas operated design may be. It works on the simple principle of delaying the rearward movement of the bolt after the round is fired. Basically rollers are forced into the trunion and held under great tension, but not truly "LOCKED" as some have implied. If it can be classified as "LOCKED" then I would argue that a straight blowback firearm like the Hi-Point is a slide-locked design just because of the weight of the recoil spring and slide. This is a ridiculous argument for people to make, since usually it is just them wanting to save face and not accept that they may be wrong. But other than that, I have no opinion. UNIVERSAL MANIPULATION METHOD With the roller-delayed blowback system, the good thing is that it is consistent in how it has to be manipulated. Whether loading it for the first time, reloading, or correcting malfunctions, the basic process is the same. First thing you do is lock the bolt to the rear with the charging handle. Make sure your palm is facing up for strength, natural manipulation, and as a way to prevent injury to yourself under stress. This is the first thing you must do in order to release tension on the magazine and also to set it up and have it free for loading, unloading, and making it simple to get into the action. Think of it as basically setting yourself up to work less since you will be handing off the work to the heavy recoil spring for loading. When sending the bolt home or releasing it, I would encourage you to not do the "H&K SLAP" on the charging handle. I would recommend not risking it and simply use your thumb to pry the charging handle out of the locking recess. Simple grip the foregrip right in front of the magazine and flick the charging handle to the left firmly and quickly. It is really consistent, and you will not really have to worry about MISSING during the theatrical slap as I have done plenty of times while running the rifle. ROUGH HANDLING
