What’s a “Frankengun”? Well it’s a one-of-a-kind rifle that has been pieced together from a variety of different parts and components. It might be a little bit Bolt Gun mixed with a little bit AR-15. Or it might feature some home-made components unlike anything you’ve seen before. The end result is a unique rig you won’t find anywhere else.
We’ve selected these five Frankengun rifles from an older thread in our Shooters’ Forum.
Frankengun #1 — The EXO (as in Exo-Skeleton)
Forum member jm850 calls this tube-framed wonder the EXO (as in “exo-skeleton”). He says: “This is a prototype I designed around a few core concepts that stick out to me on a traditional configuration. Eliminating stresses, lowering recoil moment, and improved barrel cooling. I’m really happy with it so far.”
The EXO is a very unique rifle. We’ve never seen anything like this since the late Shelley Davidson’s famous Tinkertoy Rifle, a brilliantly innovative 30BR that actually won matches. (Sadly Shelley has passed away). The Tinkertoy, shown below, was truely radical, but it worked ! Could this have been an inspiration for jrm850’s EXO rifle?
Frankengun #2 — Mossberg MVG in LSS Stock with BipodeXt
Forum member BallisticXLR has created something very weird to say the least. It started out as a basic, bone-stock Mossberg MVP Varmint in .223 Rem. Then the transformation began: “I replaced everything except the receiver. It now has an LSS stock, PSG-1 grip from DPMS, XLR butt stock, PT&G lug and barrel nut, Columbia River Arms 26″ barrel with Sonoran coral snake Cerakote, A2 flash hider, Timney and Jard triggers (depending on what I’m doing), and a USO B17 which is now a USO 3.8-22×44.” That long extension tube under the chassis is a BipodeXt from Accuracy Solutions.
Frankengun #3 — A Chassis Rig in 25 Creedmoor
This Frankengun belongs to Forum member Geraldgee. This “black and blue” rig features a mag-fed Kelbly Atlas action in a McCree’s Precision G10 Chassis. The barrel is a Bartlein Rem Varmint Contour, 1:7.5″-twist 4 Groove, chambered for the 25 Creedmoor. There are some interesting .25-Cal bullets coming on the market now. You can make the brass by expanding 6mm Creedmoor, or necking down 6.5 Creedmoor.
Frankengun #4 — MDT Chassis, Fore-end Whittled by Spook
Here’s a real collection of odds and ends, but Forum member Spook says it shoots well, and is a great example of “Left-over parts made useful again”. This mix-n-match Frankengun features a Remington M7 action with PT&G bolt. The barrel is a stainless Pac-Nor chambered in 6mm SLR. The barreled action is carried in an MDT Chassis with rear folding buttstock. Up front is something unusual, a Delrin fore-end that owner Spook “whittled in the mill”.
Frankengun #5 — 6.5×47 in Accuracy Int’l Stock

Forum member CT10Ring kicked off the Forum Frankengun thread with this rifle. It’s actually not that shocking, but you rarely see a BAT action in an Accuracy International stock. The BAT VR action is mated to an AI Mag and set up in an AI folding stock. On top is an “old school” Nightforce Benchrest scope. The barrel is a very heavy Krieger chambered for the 6.5×47 Lapua. CT10Ring say the barrel alone weighs about 9 pounds, and the gun “shoots better than [he] can”.

March 23rd, 2025
We know that Competition Machine (Gary Eliseo) makes great chassis systems and Pierce Engineering (John Pierce) makes great actions. But sometimes a project comes together even better than one can imagine. The folks at Pierce Engineering crafted an Eliseo Tubegun that displayed some mind-blowing accuracy during initial testing. This was a special rifle built to a client’s spec in .22 PPC.
After his team completed the rifle, John Pierce took the Tubegun to the range to make sure everything was working right. The rifle was chambered for the .22 PPC, a known accuracy cartridge. Would this cartridge shoot in this gun? Heck yeah was the answer! The first two shots out of the gun were touching. That was promising enough. But then John drilled a five-shot group that was basically one hole! Here is that target. First two shots upper left, then the five-shot group below and to the right. Chassis-maker Gary Eliseo commented: “that’ll do just fine…”
 Disclaimer: John shot some more groups with this Tubegun that were definitely NOT one-holers. That first five-shot masterpiece could not be duplicated. However, we’re told that the rifle shot other groups in the 2s, 3s, and 4s — impressive performance for a rifle designed for prone and position shooting. This shows how well the Pierce action mates to the Competition Machine chassis.
And if the owner ever wants to show off a “wallet group” for his new rifle — well he’s got that, thanks to John’s great trigger-pulling and rifle-building. Using On-Target software we measured that five-shot group at 0.189″ (see photo at right). That’s crazy small for a new gun with zero load development. That’s also a testimony to the quality of the Norma .22 PPC brass.
Why the .22 PPC Chambering?
The customer owns other Eliseo Tubeguns, but wanted something that combined extreme accuracy with very low recoil. He also wanted to be able to shoot factory brass without fire-forming. Norma makes very high-quality .22 PPC cartridge brass that is an easy load and shoot solution. In fact the folks at Pierce Engineering custom-loaded a quantity of .22 PPC ammo for this Tubegun and shipped it off to the customer along with the new rifle. NOTE: Loading ammo is not something that Pierce normally does, but this was a special client request.
Norma .22 PPC Cartridge Brass is available from Bullet Central for $75.99 for FIFTY (50) cases. That works out to $151.98 per 100. Yep that’s pricey considering that 6 years ago this same Norma brass was just $88.88 per 100 cases. But we have seen significant inflation in nearly all premium brass offerings.

 A 7mm Snake for Santiago
Our friend Dennis Santiago has a reptilian rig in his arsenal. It’s actually an Eliseo R1 single-shot tubegun chambered in .284 Winchester. The eye-catching aspect of Santiago’s .284 bolt-gun is the snakeskin dip job on the exterior. This really creates a distinctive look. Dennis tells us: “It was Gary Eliseo’s idea to try a water-transfer printing finish for this rifle. There are many patterns to choose from — this is the WTP-260 Snakeskin Illusion-Fall Copper from WaterTransferPrinting.com. For a single shot LR gun, I figured something on the bright side would be interesting and pick up less heat from the sun in the summer.”
Dennis uses this eye-catching rifle in prone matches, where a single shot works fine. He says: “Underneath the hood, it’s a Rem 700 Long Action, chambered in .284 Win. Yes it’s a single shot! I don’t need anything else for a prone gun. Nothing to get in the way of building the perfect position.”
Dennis says: “Length of pull, offset and cast initially set the same as my similar RTS .308. My gun, my body dimensions.”
R1 Testing with Advanced Electronic Shot-Plotting System
Now that winter is here, Dennis plans to do some serious load development with this rifle: “I acquired a new ShotMarker electronic target system. I’ll be using that to test a variety of powders and bullets.” Dennis has previously loaded his .284 Win R1 with Hodgdon H4831 powder, but he hopes to test alternatives from Alliant and IMR as well. There are many interesting 7mm bullet options, such as Sierra’s impressive, factory-pointed 183gr MatchKing with 0.707 G1 BC, and Berger’s new 184gr F-Open Target Hybrid with 0.695 G1 BC.
The ShotMarker is a unique 8-sensor acoustic electronic target that instantly plots shot locations and transmits the data via WiFi to a mobile device. Dennis is eager to try his new Shot-Marker. The system can measure group size, velocity, and SD. The Shot-Marker App can then store your strings for later review, add notes to the target, and export data to spreadsheets.
A FFP 6-24x50mm Sightron Rides on Top
The optic is a Sightron 6-24x50mm, FFP MOA-2. Dennis reports: “I looked at many scopes (within my determined price range), and this is the one that had the best combination of features for for this gun’s particular application. The sight line sits about 3 inches above bore line on these guns. It’s been leveled, bore-sighted and pre-dialed for a 200-yard estimated zero for the ammo I plan to use. Those are Gen II A.R.M.S. rings. Super easy to tailor to different rail widths. Same rock-steady steel performance.”
