||These are excellent. I own a VFC M4ES 145R and these things fit better than the $20 per magazines that are available for my gun. They are very durable and fit better and feed better than the standard magazines for my gun and the paint doesn't scratch like the other ones I will most likely be buying more of these in the future.
Very well made and you can't beat the price!
Silent (All mid-caps are)
Better than the more expensive ones)
I would recommend using silicone oil when you first get them to work them in a little and they might double feed at first but after a couple reloads and unloads they will work fine again. This isn't really a con but a recommendation.
I would defiantly recommend this product to anyone that has a gun that this will fin in including the above in the description and any VFC M4 E-series gun.
