HS Armory M-nubs for R-hop systems (2-pack)

This is a 2 pack of M-nubs for R-hop systems from HS Armory. The R-hop and it's variants like the IR-hop are the ultimate hopup system on the market today and I don't make that statement lightly. The R-hop system not only greatly increases accuracy but also increases range at the same velocities. It distributes the pressure on the BB better than any other system available including flat-hops and all after market buckings. They also are intrinsically very durable and pretty much never wear out. During any R-hop install the hopup arm nub holder needs to be removed and a replacement buffer needs to be placed on the hopup arm to apply even pressure to the bucking and R-hop. The M-nub is that buffer that replaced the stock one. It's self adhesive and is made from a very soft material that allows for easy control of the hopup. It's highly recommended that you read the guide and maybe watch some videos to get the best install.
