I wrote an article back in March which pretty much concluded my HPA VSR project which I had been working on since November. The project was all but finished bar a couple of minor details (installation of a TDC mod and then painting) but the project was recently thrown a massive curve ball when Parcel Force managed to snap the stock (just after the trigger guard and despite being fully assembled and inside a hard shell transport case) whilst it was on its way to Gun Smithy for him to fit his brand new CNC TDC mod!

To say I was gutted was an understatement, so many hours of graft ruined by Parcel Forces negligence (there was evidence of a hefty impact to the bottom of the hard shell case as the corner had caved in!) and to add insult to injury, Parcel Force refused to pay out as Airsoft items carry zero compensation apparently (I thought they carried the default compensation of Ā£100 per consignment but were ineligible to enhanced compensation)!

So instead of the RIF going off to be painted once Gun Smithy was done, it ended up going back to JB3D – Custom 3D Printing & Design for inspection to see what could we done.

Upon inspection, Jake @ JB3D was confident that a pretty decent job could be made of a repair as the break was clean and along a layer line however we also used the opportunity to test other filaments and install metal reinforcement rods which we would epoxy in place.

If this testing proved successful, we would adjust the print files so that the side walls around the trigger guard area were slightly thicker, prepare them to accept metal reinforcement rods and also split the print into two pieces which would result in smoother layer lines.

The test went well with no visible break once painted and as such, I commissioned Mk3 of the stock to be printed and sold the repaired Mk2 stock on eBay to cover costs šŸ™‚

Due to the changes to the print file (namely printing 2x smaller pieces vertically vs 1x 770mm piece), the stock printed much smoother than the previous iterations and despite the additional thickness to the side walls around the trigger guard, it still looked slender and proportional!

At long last I was finally ready to send the RIF off to be finished and the agreed specification was as follows:

  • Everything to be rubbed down with wet and dry to achieve as smooth a finish as possible
  • 3D printed stock, covers, thumb screws & cheek riser to be finished in Sniper Grey (Cerakote C-187)
  • Trigger guard to be finished in Sniper Grey (Cerakote C-187)
  • Mag release button with 3D printed extension to be finished in Sniper Grey (Cerakote C-187)
  • Internal can of suppressor (part under the honey comb mesh) to be finished in Sniper Grey (Cerakote C-187)
  • Everything else to be finished in Graphite Black (Cerakote H-146)

A couple of weeks later and here she is in all her glory! It may have been a bit of a painful journey, it may have cost more time and money then I would have liked but I couldn’t have hoped for a better finish.

Finished spec is as follows:

  • Custom 3D printed stock (Mk3) in PLA-N
  • Wolverine Bolt engine
  • Original 3.2mm airline with after market fittings
  • G&P 8.5ci SLP tank
  • Polarstar MR (Gen2)
  • Maple Leaf VSR G-spec outer barrel
  • Maple Leaf Crazy Jet 430mm inner barrel with Flamingo bucking
  • Maple Leaf bubble scope rail
  • Action Army Hive suppressor with custom foam disc inserts
  • Action Army single piece receiver
  • Action Army bolt end cap
  • Custom made cylinder guide kit
  • Tokyo Marui hop up chamber with CNC TDC mod
  • Tokyo Marui bolt handle (it folds down flatter than after market parts)
  • Tokyo Marui trigger unit modified with external wiring harness
  • Cantilever 30mm scope mount with top rails to mount range finder
  • Vortex Optics Crossfire II 3-12×56 Hog Hunter illuminated scope

With the reg set at 110psi and using 0.48g BLS precision BB’s, I am getting greater than 500 shots from the tank at 2.3j (225ish fps) which I’m very happy with as I was hoping for at least 250-300 but 500+ means I don’t need to worry about recharging the bottle during a game day at all!

Credit where credit is due:

So there you have it, a 3D printed & cerakoted HPA VSR – completed it mate!

Is there a possibility you can make a stock for sale, I’m building with similar internals, most importantly the tank and regulators are the same. Thanks.

    Thanks for your interest but making this commercially isn’t currently viable due to the amount of work involved.

    That said, as and when I have made a new/improved version, I have then sold the old version so there is a possibility that the same may happen again in the future šŸ™‚

Are you selling a copy of the 3D plans anywhere ?

    axerite · September 6, 2021 at 3:24 pm

    Hi Graeme, thanks for your interest but I am not currently selling the files, sorry!

Is there any way to access the files used to make this stock? This is the only stock I’ve found like this for a VSR and having the files available to the public would be amazing.

    Hi Jacob,

    Thanks for your interest in my project but Iā€™m afraid I do not currently have any intentions to release the files to the public, sorry!

    Thank, Jon

      Are you selling these stocks or is it possible to purchase one? Thanks
