How do you know if an Airsoft rifle is good or not and worth your hard earned money? You need to do a test drive or see the parts after they have been heavily used and make the call yourself if the rifle is good or not. In this Knight’s SR16 parts review the test drive will happen and the results will be seen up close.

The nozzle and hop up unit for any Airsoft rifle is very important to ensure proper feeding and air seal. This nozzle of the Knight’s SR16 is dirty from being used at the recent shooting events over a four days of dusty continuous shooting.

The rifles were used very hard by first time users just as a rental in a CQB field would be but add the dust and debris from the shooting range and bad things can happen. In this case the inner barrels were cleaned before each event day but during the day there still was debris build up that got in every place possible of the Airsoft rifle. One of the winning factors of the Knight’s SR16 would be the one piece hop up unit that is used to better seal and keep dirt out. No problems from this or the other demo rifles with this amount of dirt inside.
The external parts of the rifle can be tampered with by the user or just wiggles free if it is not designed correctly. A great example of a solid part and how it is designed well will be the magazine release and how it is based off a real firearm design and not using a small screw what can loosen over time. Some Echo1USA rifles in the M4 styles use the older style magazine release with the small screw which is fine but the mindset for the Knight’s was to a two prong attack for the market. First make it budget friendly and to the liking of KAC for the Knight’s trademarks and secondly have it built to last with very little to no maintenance for the shooter. In this review the many other parts that make the Knight’s SR16 a solid platform will be highlighted.
The motor is another key part in the function of the rifle and it must work when the time comes. The motor pinion gear is of course made out of steel with the D style in case it needs to be changed out. Upon a closer look of the pinion gear there is very little to no wear on the teeth and that is due to the proper height during the heavy use. Every time the trigger is pulled the motor will crank over and spin to pull the gears to complete each shot. That cranking motion is the vibration felt in the pistol grip and just like an automobile the parts need to be secured otherwise a failure will happen. The motor in the Knight’s SR16 will have a hard time failing since the adjustment screw is a large screw with more than enough surface area and a drop of loctice to keep the prefect adjustment over time.

The motor will take most of the abuse during the firing process with the heat and power going through it. A commonly overlooked part of the Airsoft rifle is the motor and the status of the parts to make sure it is working properly. Many times players will clean their inner barrels but forget to check their motors after an extended amount of use. The motor commutator can get burnt and dirty and blocking the power from the battery and stopping all movement. A way to do a quick inspection of the part is to manually spin the pinion and watch the commutator for any burnt marks or deep grooves. After the heavy use of the four days and no stop firing the motor looks really good and can keep on being used without being cleaned or serviced.
The main reason the motor commutator looks so clean after all the use is because the brushes are a solid face design to ensure the most contact for the extended period of time. The brushes are important in how they are pressed inward and that relies on the springs behind them. The motor is a very complex part in the Airsoft rifle.
A solid foundation is very important and the 8mm solid steel bushing is perfect for that. The solid steel bushing is a change for the Knight’s SR16 when compared to the other rifles in the Echo1USA lineup but that due to the desires of KAC and wanting a solid rifle inside and out with their name on it. The 8mm ball bearing that is used in the other Echo1USA rifles are great for the stock gearbox stresses and even up to the 500FPS. Just in case an upgrade was needed the strongest part is already installed with this rifle. Being that this gearbox uses a steel bushing it will not fail or erode over time from the gear axels. Some Airsoft rifles use a brass material for bushings which is weaker than the steel and will fail over time with moderate use. Echo1USA would not cut corners in this department.
The grease for the Knight’s SR16 is applied in the key parts and just the right amount. There is a good amount to keep the bushings and gears greased without going into places that it does not belong.

The gear grease can move inside the gearbox due to hot temperatures such is sitting in the sun all weekend at the range but it will still not cause any issues by getting into he trigger system of the gearbox. This is the factory grease amount and after the non stop heavy use it still looks good. The gears are properly shimmed from the factory to make sure everything works smoothly.
The piston of the Knight’s SR16 Airsoft rifle is a made out of nylon fiber and the same found in the RedStar AK series. The advantage of the lightweight piston is to keep the cycle rate up without having extra weight to slow the process down. The piston is a regular TM spec with the tooth design and the second tooth is present. The stock setup is able to work great even with a lipo during the demos during the show without any signs of damage.
Current trends in Airsoft claim the use of a lipo battery the Airsoft rifle will explode when no MOSFET is present but from the pictures the wire harness looks great and no issues present. Being that the Knight’s SR16 does not include this upgrade feature the rifle is still able to perform very well out of the box and keep on working without issues. The rifle is still using many other upgrade parts it still makes for a great complete and field ready package. A MOSFET can be installed later but that will be up to the shooter since there are several to choose from and none are the best since they vary in features.
Overall the Knight’s SR16 Airsoft rifle held up great from the events of the non stop shooting and you will find them in some CQB fields for the rental fleets for the same reasons highlighted in this review. The Knight’s SR16 series is a great choice since it is built to last for around the $200 mark it will be a great investment for the Airsoft game.
