At Hooper Gun Works, we go over 100% of these Rock Island Armory factory uppers, disassembling them completely, inspecting all parts, and replacing key parts as described below. This greatly ensures that your optic plate with integrated rear sight will be able to be removed when you’re ready to integrate your Vortex Venom compatible optic, and your extraction will be the best it can be. If you don’t see this advertised by the competition, they likely just pass them along forcing the buyer to “roll the dice” on having a successful build.
These uppers have been test fired by Rock Island to ensure fitment on their end, and as such, will show some normal cycling wear. We also test fit on our lower prior to shipment. Consider these as “new other” condition product.
This upper is made by Rock Island Armory in the Philippines. Its proving to be a great place to manufacture for both 1911 and aftermarket uppers for Glock. That said, this upper will require more detail to fitment on lowers that you may already have built up. They are a little bit tighter and therefore less forgiving to rail alignment errors than normal U.S. aftermarket. The best way is to assemble a new lower at the same time as fitting this slide, so that rails may be best adjusted for success prior to pinning. This is what we did, and had no problems on any of these that we built up into full pistols. Your specific upper will be tested for fitment on a lower that we use for all these uppers so that we know its going out the door with proper Rock Island specs.
