Just got my first Bob Long

[jokers]

I just traded a marker for a used HK Army Ripper Vcom, almost identical to this one. I like it a lot the only issue that i have and this may be addressed with using another barrel is the sound signature. Is there anything that bob long fans would recommend i change out, replace or otherwise change on this marker? Will the change of barrels lower the sound signature and is there any barrel that i should look for that works better or just use my favorite cocker threaded barrel?

[Ecapnation]

Hk army rippers and Bob long rippers were slightly different iirc

[jokers]

I almost get the feeling that the HK ripper was more along the lines of a Marq Victory since from the manuals they look similar. I have been looking for a manual for the HK army ripper and been unable to find one yet.

Maybe a Dye UL barrel. What are the reg pressures set at? The VIS engine shouldn't be too loud unless it's not tuned properly.

Does it sound like this?

It has a slight bit more crack, rather then the pop that marker is making, so I will go ahead and test the pressures to see where they are at. When i was trying it out my velocity was high as in 300-315. When i lowered FPS via the HPR to 270 it still had more of a crack then a pop, it was not terrible and that is why i did not think tuning just barrel.

I had a Bob Long Vcom. I never put the poppit engine in mine. It was an amazing marker. Never leaked and never had to rebuild it from factory seals. Use a good amount of dow 55 lube IIRC. Be super careful with the connectors for the screen. Hope your's is a good one. I know hk army ain't known for quality in their soft goods departmemt. .

What bore id is your barrel back? I ran mine with the stock vcom barrel and it was very quite. Though I prefered to run it wit my 8in Check It barrel. Maybe get a 32 Degrees Whisper barrel?

[jokers]

SMH I should know the size i was using but for some reason i do not, it was the middle one that fit the paint the best at the time. I will gather that along with pressures and post back.

I have found with mine that the stock barrel was the best. Mine came in with pressures all out of whack from the previous owner and it was a canon. I adjusted that and it's better now. But it is still louder than other BL's I have owned.

I have an issue with it occasionally breaking balls in the breach and I am trying to figure that out. Otherwise, it works like it should. They got a bad rap, but it's not as bad as other BL owners make it seem. This is the second one that I've had and the first one worked fine. My son bought it used and we sent it to some guy (I wish I could remember how to contact him) that tuned it up and had it working great, Same thing with that one though, the previous owner had it all out of spec pressure-wise and it didn't work like it should. Once that was fixed it shot great. I got mine for $350 and it was like brand new, so if it becomes a wall hanger, it at least is a nice looking one!

[jokers]

If you happen to remember who it was that you had tune it I would love to know, I plan on doing a quick run through and seeing if i can tune it myself but having someone who knows these is always better.

[Cyberpyr8]

Flawless Airworks (Jacob Salas) in Texas can work on them. I know he's slowing down right now due to a new job, but he definitely is worth waiting if you have to. He's great at tuning BL and the HK guns. I don't remember the other dude at all. I have been trying to find the Insta post he did with it but it's long gone. Dave something. I can't even remember where he was located. But Jacob is the man now for most BL/HK stuff. I've even sent him a few PE guns to work on.

[MrKittyCatMeowFace]

I got mine off ebay used and they came with this to set the engines up correctly. I don't know what is a good price for them. .

[jokers]

It came with the tester I just did not think to test it, I thought since it was working it was okay and just needed the hpr lowered I will test it and lower it accordingly. Thank you so much for the info though and I am sure it will be good if someone else does not have one.

The naming for this series of guns has gotten so muddled, especially with all the paintball knowledge leaving forums and dumping into the cesspool of Facebook.

That said, there are 3 different engines for Victory's:
1. Supercharged (oldest engine, inline poppet)
2. VCOM (spool engine)
3. VIS (newer inline poppet)

And then a bunch of body types:
1. V1 (has one long window on each side of the body, short HPR body, LED board)
2. V2 (also called "T-Rex", two smaller windows on each side, originally had the short HPR and LED board but was reproduced a few times and later got a long HPR and OLED)
3. Ripper (distinctive ribs on each side, also produced with different HPRs and boards over time)
4. VIS body (no windows)
5. VCOM body (two big windows that wrap over the top of the body)

To add to the confusion, the HK guns have different feedneck mounts (lip instead of original smooth tube) and they also simplified the trigger guard milling that reduced the firing chamber volume, which of course increases operating pressure.

*Basically* you'll probably want to tune it yourself and make a note of the pressures you end up on because who knows what's going on with all these combinations of parts.

I had to scroll waaaaaaayyy too far down to see someone finally mention this

[Frmrspec]

So one thing to keep in mind is HK used the VCOM name on ALL their reproductions even though they came with a VIS engine…. VCOM stood for “Victory Change Over Motor” which was their spool valve.

historically the VIS and Supercharger/d had a distinctive “crack” in the shot.. they were both more efficient than the spool but louder with a distinctive shot sound…

historically you could “tune” the systems to whatever was most important to you.. me personally I always tuned for the quietest/smoothest marker I could, at the sacrifice of efficiency..

I think stock the Vis engine ran at about 7ms dwell, I always bumped it up to 9-10 for both reliability and sound signature even higher in the cold… you can tune the pressures using the traditional lurker method

[Cyberpyr8]

What pressure are you running on yours?

[jokers]

Just to make sure you are talking about this method?

"1: Back out both regs completely or set both the HPR and LPR to 0 psi.
2: Raise HPR slightly (only to set LPR for cycling).
3: Raise LPR to fully cycling ~45 psi or so.
4: Raise HPR until velocity begins to stop rising as you increase pressure.
5: Raise LPR to desired velocity.
6: Lower HPR a bit, then raise if necessary... You're trying to find the best HPR setting at the LPR setting you have. This may put your velocity over 300/285.
7: Lower LPR slightly to field velocity."

[Frmrspec]

Cyberpyr8 which engine? I primarily use my Vcom engine which works with approx the same LPR, but about 40-50psi less than the VIS

jokers essentially that but a little different (may be the same just worded a little different) Once I get into FPS range I raise lpr until velocity stops increasing, then I back off HPR, and reset LPR to that new HPR settting… I don’t try to fine tune FPS via LPR

[Cyberpyr8]

Stock Vis engine. I have my pressures now set at 75 and 205. I had the dwell at 6 but I bumped it up to 9. That's what the manual says they should be. I was just wondering what people are really using. At these settings, it sounds and shoots fine. I am going to look at replacing the detents to see if the ball breaks stops. It seems to work great other than that.

[Frmrspec]

Cyberpyr8 also make sure that your pillow tip is still in place… but that sounds about right. May be a little high on the HPR I thought they were around 180-190. But like I said I rarely set with a pressure tester

[jokers]

Frmrspec If i am understanding right I am sweet spotting the HPR first, then sweet spotting the LPR, then using the HPR to control FPS is that right?

[jokers]

Does anyone know if the field one grips will work on the HK Ripper? They look like they would work and Field One shows how to mod them for a lot of Bob Long markers, so I think i should be safe but I always like it when someone else has taken the leap before me.

[Frmrspec]

Yes.
