SPECTRE RDP M4 barrel block upgrade / replacement - flush, threaded and muzzle brake

cults3d

The stock Spectre RDP has a very thin flimsy, boring and useless piece of plastic that holds the inner barrel. I've decided to design a thicker and more usefull set of blocks to replace / upgrade that :) There are 3 designs in this package; [Flush] As it name implies a block that sits flush with the front end. this is for people that just want a better and thicker barrel block, without anything extra. If you are design savvy you could also use thise as base for your own designs! [Threaded] This design adds an threaded airsoft spec 14mm ccw endpiece to the existing base, this way you can attach all the muzzle devices you desire and customize your spectre rdp to your hearts content! [Muzzle Brake] Lastly we have a muzzle brake, it slots into the front and adds a muzzle brake to the spectre rdp that makes it look like it was part of the body all along! ----- content ----- RDP barrelblock V2 Flush RDP barrelblock V2 threaded RDP barrelblock V2 muzzle brake
