Pump action kit for AEA HP Max .50 .45 .510 cal air rifle Color Customizable

Description: I am selling a pump action kit for AEA HP max 50 or 45 cal air rifle. It works well with original round magazine. Standard kit fit airrifle 13 inches with regulator or 22in with or without regulator I can customize it to fit 10 inch pistol, or 13in barrel without regulator. For shorter pistol, check my other kit. Note: The bottom pica rail receives verticle handle or bipod, howereve don't use them to push the pump action due to dramatically increased torque. You still do the puming by puting your hand in front of the bottom pica rail, grab the slider and pull/push. The material is hard rubber-like so the pica rail won't be uncomfortable (at least to me). The kit for sale includes a front slider, a pusher, and a rear dovetail clamp, as shown in the 3rd picture. Compatible with original magazine! Airgun and bipod are not included. The forehand slider Is 3D printed with solid premium tough filament at100% (max allowedby printer) infil, The slider comes assembeled with a carbon fiber /stainless steel composite tube. A pusher made of aluminum alloy is another critical part in the kit. The rear dovetail adaptor is 3dprinted with solid carbon fiber PC at 100% infill. Both parts need to be installed for proper functioning. Instrunction will come with the kit. I offer post-sale help including replacement of faulty parts or modification if needed for functioning. You can choose the color of the front slider. Rear adaptor is always black---I believe carbonfiber PC is the best materiual for the purpose. I put demo kit (normally a previous version or experimental version--function well for pump action anyways) for 20% off occasioanlly---just check my other items! Note: I can do resonable modifications to the front slider, including adding or removing pica rails, adding or removing letter, etc. Pls let me know. Allow 3-5 days to make. Those premium filaments takes ~30 hours to print to achieve high strength. I always have one set in stock--just ask since the color is normally gray or black which may not be your choice. The air rifle shown in the main picture is a 13inch version sold by bintac and you can check detail from their website. The other picture is a 22in version with the pump kit+ barrel band.

Works really well with the bullpup kit. You can find the bullpup kit on eBay but require a bit cutting of the bullpup stock (easy to do with a rotary tool such as dremel). It can solve the awkward charging/loading issue with bullpup! It takes some practice to get famaliar. One tip is that if the 1st cycle went wrong, don't try to cycle twice or you will get double load and have to use a rod to remove jammed pellets. It may happen to original bolt action too. A bit silicon grease on the bolt handle-pusher hoop helps a lot to make it smooth. I am a fan of HP max so you are welcome to discuss technical problems.
