These aren't pure carbon fiber. They are 3D printed plastic with carbon fibers in the plastic. [Customer did not contact us for refund. Pure Carbon Fiber is a fiber. It needs a resin for strength. Our material is one of the strongest in the world and is ideal for the application]

This extender works great. However, I had to glue my last remaining one in place. They do not snap on. I purchased 2 and installed them. And tried them out at the range. After I got home, I noticed one had fallen off. Now I have to buy another one. [Customer was sent new keeper pieces that don't fall out. This issue was caused by a rare lapse in quality control.]

Well made easy to install works great glad I got one for both sides.

Very useful product especially when wearing gloves. Easy to install and remove should you need to.

Love these! Super comfortable, easy to install, light, 100% improvement over the stock charging handles. My only issue is that after enough vibration the wedges tend to work thier way out over time. I have thought about adding a little glue, but that may be hard to remove. So, I think I am going to add a set screw to make mine more solid. [Issue resolved with current quality control checks on keeper pieces].

Super easy to install. Work badass

Does exactly as advertised, install is super simple, makes for a much more positive and faster charging of the PS90

Great part, makes the handle 100% easier to operate. A small instruction sheet would help but I got the assembly figured out after a bit.
You first pull out the insert, then snap the larger piece over the handle and then the insert locks behind the factory handle, locking the whole assembly.

Simple install works great, easy to use even with heavy gloves on
