I considered making a pump for it, but all of the tutorials on this still require the sight rail to move. I considered bypassing the sight rail completely with a pump, but my design would have called for a complete revamp of at least half the blaster. THEN, I remembered my Maverick (that I wish I would not have lost half the pieces for). On it, I fixed the sight rail to keep it from moving, then placed a cocking knob on it. So that's what I would do to the Recon.
The whole process was pretty simple, so I'll just make some pics and can explain in further detail if there are any questions.
I removed the powertube from the charging bracket, then placed a nut and bolt through one of the holes. Before doing this, however, the head of the bolt was ground down, so as not to interfere with the magazine or the barrel entry.
This shows the powertube inserted into the blaster. I chose to put the charging handle on this side because I'm a lefty and this allows me to charge the blaster without the need to remove my hand from the grip. Notice that the receiver slot had to be widened to accommodate the nut.
The right side of the sight rail was trimmed out to allow the charging handle to fully retract. I marked it's position and glued it onto this half of the receiver to keep it from moving.
The left side of the sight rail was left in tact with the exception of grinding down the catch on the inside of it. I did not glue this side, due to two hidden screws on the right side of the receiver, and it is held in place with its own screws.
Now, the sight rail is stationary and allows me to use the fancy dot sight without it moving (and sliding onto the barrel when I charge it forward). I plan on placing some sort of handle onto the bolt threads in the future.
