ACCESSORY RAILS ARE INSTALLED FREE ON NEW ORDERS.
NOTE: All accessories will fit both the new model CCU (straight front) and the older model CCU (angled front)
You can order any combination of accessories that you want. Here are some examples of what different combinations look like. What model CCU you order makes no difference to the accessories you can put on it.
NOTE ABOUT THE INTERCHANGEABLE STOCKS SHOWN BELOW: Older models of the CCU did not have the interchangeable stock system. The older units had a welded on fixed stock. There is available a retrofit housing kit which accepts the stocks shown below. This kit includes an updated housing and a recoil buffer assembly. This can be changed out by the customer or call Mech Tech and arrange to send in the unit for retrofit. We have also changed the fore grip and standard rail. The fore grip is now injection molded, black, with ribs (see Glock or 1911 pages Basic Unit picture). The standard 5 3/4" rail now has Picatinny slots for it's full length instead of 3 pairs of slots. If you have the welded on stock, all of our accessories are 'new'. Have a look at the rest of this page and see if there are any enhancements you'd like to get with your new housing.
