The receiver fits a version 3 gearbox and a g&g front end perfectly! (only had to remove a slight tab of metal for the front end to slide in properly, but was no big deal)
Product - 3.5-4 / 5
Service (airsoftgi) - 5/5
Stronger than the plastic stock items, and fits perfectly with a version 3. Front metal tabs can fit many different types of ak fronts, but for the g&g you have to remove little bit of metal.
Painted well, holes line up, and a snug fit.
Airsoftgi.com did a SUPERB job at shipping on time, without any hassles. The price was good and the customer service was amazing (tracking numbers for postage, estimated time of arrival and details on the order process)
Magnesium metal is weak compared to other metals. The magnesium used is almost like a chipboard type of magnesium (not one solid piece, but a flaky type of metal casting when you cut into it) It is prone to snapping (i snapped off a stock attachment piece of metal on the back of the receiver, just by screwing it into the wood stock (not forcefully or anything, just weak metal not able to take any real sudden force)
G&G could of used aluminum, iron or steel to counter this, but then weight and cost would of been effected negatively.
The product's cons are on G&G manufacturing side of the business, so airsoftgi cannot be blamed (as they did amazing job being the retailer in this)
For the cost of the product, it does the job, but it could be stronger!
