Yes but you will need to mod your bolt and get a very specific spring. You will have to bore out the back end of your bolt and place the spring inside the back of the bolt over the bolt guide.
This will not decrease your rof as the decrease in dwell will more than make up for any possible increases in recharge time (unless your spring is too stiff).
Also keep us updated on how that spring works over time. I am a little worried that with nothing to actually guide it and not much to hold it in place the spring will bend or even work its way off the bolt guide after extended use.
for the how to with pics.
