I am posting some upgrades I have done in case it might help others wanting to do the same thing but unsure of what works and what does not.
Crossover Upgrades and Modifications, or How to Convert a V1 Crossover to an XVR
This is a V1 Crossover with Freak barrel kit, short foregrip, new trigger, toolless grips, on/off asa a Virtue LED Board and MRT bolt which almost duplicates the Crossover XVR (only better)
This second marker has a Freak barrel kit, DW Whip Tip, carbon fiber foregrip, new trigger, toolless grips, on/off asa, Nummech drop forward and MRT bolt.
1) Barrel ; I have a Freak back with a Deadlywinds 6" Whip Tip. I also have the 8" Whip Tip that may come in handy when playing airball. The fact that I already had the A5 Freak barrel and inserts was one of the main reasons I got the Crossover to begin with. I could convert parts I already had to a more modern and effecient platform. Using the XVR Barrel kit would accomplish the same thing, but it will currently cost you $129 to get 3 backs @ .680 .684 & .688 and a front.
2) Fore Grip; Be aware that in order to change out the front foregrip, you have to remove a machine screw inside the handle and then take the handle off the air fitting that screws into the marker’s receiver. I used a 5/8” wood dowel, inserted it in the end that goes into the marker, and warmed the nylon handle over a gas burner on the stove to loosen it. Then I pulled it off with pliers. I made a carbon fiber fore grip to match the barrel tip, but if you want to put the XVR handle on, it will need to be lined up on the marker and pounded on with a mallet. Then the machine screw can be reinstalled.
3) Trigger; Go to the Tippmann website, fill out the form and get the free trigger upgrade in the mail. Leave out the orange spring and good to go.
4) Toolless grip; This grip is no different than the stock grip except it does not have the gray panel inserts and it has a small cut out on the right side for the button to pop it loose. The grip upgrade really amounts to making studs out of the cap head screws on the left side of the grip. I ground them down with a medium sanding wheel on a dremel until they were just slightly larger than the threads. I applied blue locktite to the threads, popped the left grip over them and tightened until there was no gap between the grip frame and the grip. If you have a dremel, this is about a $1.00 modification. It is quite easy to pop the grip loose, although I doubt it would be possible with gloves. It certainly beats digging around for an allen wrench to install, replace or remove the battery though!
5) On/Off ASA; Probably the most important upgrade IMHO. This will eleminate worn bottle threads, and it also changed the bottle position so the gauge is facing the left. This is good for me as I usually hold the marker in my right hand and I will remember to look at it more often. To match the marker color I painted it, but a better option would be powder coating. Maybe later. They are available in red, olive and titanium with a thin anodized coating, so it requires sanding prior to refinishing.
6) Tippmann Case; With the drop forward, my marker won’t fit the stock case, so I am using a laptop case instead. It fits the marker perfect, holds the barrel, tips inserts and tools nicely, and keeps everything organized. The Tippmann case would be fine otherwise
7) Nummech Drop Forward; I installed this drop forward and really like it. It places the barrel directly in front of my face, shortens the overall length by about 3” and works great for me. It installed in just a few minutes, is sturdy, fits nicely, has no sharp edges and does not leak air. I would give it a 9 out of 10. If the finish was satin black instead of an off brown shiny color it would get a 10. I painted it too and may powder coat both the drop forward and the ASA if the finish deteriorates to quickly.
8) TechT MRT bolt; Raises velocity by about 25fps so logic would assume you would get better gas efficiency by turning down the input pressure. It lowers kick slightly, but considering the weight of the marker with a full hopper and tank, that would be secondary. I have not burned through enough ammo in 1 day to know how many shots I get from my 45/4500 ninja tank, but I will post back when I have it counted.
Other possible upgrades;
AC Thread adapter; Lapco has had one of these for sale for a decade, but hey, it is nice of them to offer it.
Toolless XVR Bolt; I don’t see the need to spend $65 so I don’t have to use a wrench to pull out the bolt. I don’t usually do that at the field.
Virtue Board; I have heard it is a significant improvement, but I haven’t had any trouble with programming the stock board and the fields I play at don’t let you shoot over 15 bps so no need to change it. (yet)
I am sure there are a few things I forgot, and I have no doubt there is room to add a few more as time goes by. I hope this helps anyone wordering about how to upgrade their V1 Crossover with XVR components.
