I was one of the early users of the “A.F.G” along with a few other products from Moruzzi’s. Before I get into my opinion on these rail covers. I would like to say that the customer service, attitude, and quality of the product would lead me to purchase any one of the products Moruzzi’s offers for a large number of applications. Not only do they look great, but they are also durable, lightweight, and backed by a company that is proactive in satisfying their customers. The Aerolite A.F.G I received weighed .769 Oz W/O Hardware. The hardware was .085 Oz (2) for a total of .854 Oz. There is not a lighter foregrip on the market that is as versatile and usable as this one (I was unable to find anything even close to this light for the size. I love the “Shorty” stop but this one takes the cake for my personal preference. I had the opportunity to use these in two separate weekend long carbine classes and have used them almost daily since installing. They have held up well, and I have not hesitated in giving them a beating. I am not affiliated with Moruzzi’s and have not been tested a large batch of these so the weight may very slightly but in general they will be lighter than anything currently on the market, I just wanted to provide a general weight range for those building lightweight carbines/rifles. At the time this grip was in the prototype stage, so I was given the chance to test this out before it hit the open market. Being the case, I was intentionally brutal on this one during my two weekend long classes. I used it as a wall stop, braced in on car doors as I shot, and generally beat on it hard. I was initially a little skeptical about how it would hold up given the milled-out design, but it took everything I could throw at it. I found this one to be particularly comfortable in the later hours of the day when fatigue set in. I have had wrist issues in my support hand following a motorcycle accident when I was younger and the angle this grip is set at is killer! The concave angle on the back side of the grip allows for secure handling as well as a great thumb slot when bracing against a wall. The chamfered edges prevent snagging on gear as well. Installation was a breeze and they come packaged like a product well outside of their price range. I also tested the (V1) “Shorty” Hand Stop, and the Textured “Tactical Rail Covers” (3-slot), so feel free to head over and view my review on those two products. I will also be purchasing the “A.F.G V2” and “Micro Stop V1” and potentially the “Stright Edge” for testing and reviewing, I will post separate reviews for those items at a future date. I can not speak highly enough of Moruzzi’s and their owner!
