"I have had no problems with this gun. I t has been the perfect weapon for everything I do. The only problem I had really with it was the orange tip. It would sometimes Catch BBs but I just dipped it in hot water and took it came right off. After that the thing was amazing. It quickly became my favorite gun in my armoury and i named it "Kitten." You want a gun that out of the box will kick ###? Get this gun You will not regret it.

"In short this gun is good for what you pay, (a permanent "Sale" so it's always $225.) I have used this gun in a few games and have had the same problem as many with the return spring on the blowback/charging handle breaking. However, DO NOT LET THIS DISCOURAGE YOU FROM BUYING THIS GUN. Many airsofters take the charging handle off anyway and the blowback was just kind of annoying. Other than that the gun performs flawlessly. Shoots 390+/- with .20's and 330 with .25's. The fire rate is very nice however I almost never use full auto considering I have it set up for DMR style playing. The Silver Edge gearbox is a great work of engineering from APS. It runs very smoothly with very little of the screetching you sometimes get from cheap gearboxes. The accuracy of the gun is good however APS NEEDS to upgrade their hopup units. If this were to happen the gun would easily get 5 stars however the hopup and charging handle are just minor problems. I am planning to upgrade this gun with an Angel custom barrel (494mm), new hopup (prowin CNC chamber), Prometheus purple flat-hop bucking, Prometheus flat-hop nubs, & angel custom inner barrel stabilizer. This all costs right around $150 without coupons...very inexpensive DMR upgrade. If you plan on making a DMR gun or are just getting into the game and want a longer range gun the APS Silver Edge 12.5" is perfect.

Very good build quality
Gearbox is VERY well made
accurate (still reliable around 200ish feet)
high rate of fire
390 fps
easily upgraded (kind of the case with all guns but whatever)

Hopup NEEDS to be improved by APS
charging handle problems

"The APS Silver-Edge gearbox is one of the highest performing gearbox I have used. The power drain is extremely low right out of the box without any further tuning needed. Highly recommend this series!!

APS Silver Edge Gearbox Full Metal 12.5" M4 Airsoft AEG Rifle

The APS Silver Edge 12.5" M4 Airsoft AEG Rifle comes from the factory decked out with a 12.5" metal Keymod style rail system, a full metal receiver, retractable stock tube, APS 45-degree flip-up sights, and APS' new Silver Edge gearbox.

The full metal receiver is coated with a matte black finish and features stamped trademarks for a realistic look and feel. The full length 20mm top rail is great for any type of optics you decide to use and the 12.5" Keymod style rail comes complete with 3 additional accessory rails for lights, lasers, vertical grip, and other tactical add-ons. A retractable crane stock finishes off the rear of the gun while an aggressive mock compensator finishes off the front.

The all new APS Silver Edge Gearbox utilizes a unique polishing technique to remove burrs and surface imperfections from the gearbox shell. This polishing leads to an incredibly smooth and even finish that will reduce friction and lower the gearbox load. These improvements lead to a more efficient gearbox that will use less power, generate less wear, and allow for the smoothest cycle possible for enhanced performance as well as greatly extending the life of your gearbox.
