I think it should... I bought a composite tri-rail system for the CX4 air rifles. I bought four aluminum threaded post's and four stainless c-sink machine screws. Drilled four holes at the proper points on the fore stock and it bolted right up. A perfect fit - all for under $30.

I have used Tapco & cheapie Thermold brands without problem. I buy Thermold 30 rounders from my local Sportsman's Warehouse for $7.99 plus tax, 20 rnds for $4.99 plus tax.
