Boring out the main guide rod...



I took two non fluted guide rods and bored them out today. Decreasing its weight by one ouce - and increasing volume.

It doesn't seem to change the pressure the marker runs on in any significant way - but would, in theory, make the marker more consistent in rapid fire.

More testing is needed. Likely the results will be anecdotal.

I bored out the back to roughly .400 and the depth of the inner hole is 2.5 inches. I think this leaves PLENTY of material, given that it is stainless, for strength.

With a sharp bit and a Lathe - it takes a matter of minutes - I tooled up - and finished two in under a 1/2 hour.

Yeah there's plenty of meat there. I recently did the one on my pre-2k. My goal was to add some volume and try and get the pressure down a bit. Well the main goal is actually lighter springing. This was a self inflicted problem as I'm trying to get a pre-2k body down to 2k pressures without out modifying it to 2k specs. Thought some volume down the pump rod might do the trick. I haven't tested yet either.

Interested in seeing your test results. I'm not sure how conclusive mine will be though. I not only bored the rod but also swapped out some lower end parts so it would be more like comparing apples to oranges.

have you tested em yet?

i would love to know the fps difference (if it even changes) from 2 identical setups minus the guide arm
or the psi difference to get em back to fps

So - here is the initial findings.

J2L - quickly switching back and forth between a 'normal' guide rod - and a bored out guide rod - 10 FPS increase.

Huh?

I tested it with REALLY consistent paint (+/- 1 or 2 over the Chrono) and it was consistantly 10 fps higher.

Will test my S6.5 and see what I find.

im assuming you did this without adjusting anything else?

sounds like this will increase efficiency..definitely something ill consider doing.

This looks like the guide arm from the Checkitt Products pump kit that is essentially a CCM rip-off. I used it on a 2K Sniper, and anecdotally had some great results. I ran the regulator at about 250 with a low pressure (340psi) Crossfire 45/45, and would consistently chrono 280s with the IVG way out. I could shoot all day on a single tank. Now I don't remember what springs and internals were in the gun... Probably stock WGP. As far as I could tell, the extra volume did in fact push up the velocity, without an apparent loss in overall efficiency. Some actual data would be great to see!

here's the link for the Checkit Products pump
