Our chambers are headspaced for optimal accuracy while retaining loading and ejection reliability. FoldAR does not guarantee a specific group size for an individual shooter, but the rifles are designed to achieve 1 MOA after a break-in period and some operator and ammunition experimentation.
Independent TEEX testing averaged approximately 1.0 MOA using our older outsourced barrels. The in-house barrels now in production are measurably more accurate.

Yes. Two years of in-house and independent third-party testing, plus field rifles in daily service, show a consistent return to zero after hundreds of fold and deploy cycles across a range of temperatures and operating conditions. We have never recorded a measurable point-of-impact shift over thousands of rounds. TEEX measured return-to-zero capability at approximately 0.05 MOA.
One edge case
Firing the rifle until hot, disengaging the locking mechanism, then immediately reconnecting and continuing to fire relieves pressure on the connection while the tapered parts are microscopically expanded. That sequence can produce a very slight POI shift. There is no practical reason to fold and deploy mid-string — and even then, POI settles back within a few rounds.
None. The folding mechanism has been independently tested by TEEX, which concluded that FoldAR products are identical to standard AR-15 firearms with respect to the safety of the design and its function. Even failing to engage the lever and hook does not create a uniquely dangerous condition while shooting.
That resistance is the SHUT feature, our invention alongside the folding barrel interface. It creates tension between the upper and lower assemblies so that, once pinned, there is no wobble between them.
To assemble
- Insert the front takedown pin first.
- Squeeze upper and lower together toward the rear with one hand.
- The rear takedown pin will engage.
To disassemble
- Squeeze upper and lower together toward the rear with one hand.
- The rear takedown pin will disengage.
Pull the charging handle rearward a couple of inches. That releases the bolt from the barrel extension and the rifle folds. Use the same technique to deploy. Leave the bolt in the forward position while the firearm is folded.
Folding cuts 8 inches off the upper receiver assembly — a far more compact package than a traditional AR-15, even one with a folding stock. That buys discreet carry options, storage of a full-size rifle where space is limited on duty, and travel without a long conspicuous case.
Unlike disassembly solutions, the FoldAR stays fully assembled and ready at all times. No loose parts to keep track of, no awkward assembly and stowage drill.

Unlike other folding firearms on the market, the FoldAR platform is a true AR firearm suitable for a range of calibers — some with an effective range well beyond 1,000 yards.
Other takedown models built around the AR platform are bulky, or use an awkward takedown and assembly process that is slow and unreliable, or require two or more separate pieces to track and pack. With the FoldAR, the firearm is always together and fully assembled. Deployment and stowage take seconds. Cleaning the bore and star chamber is easier, not harder.
Yes. The platform was built around maintaining as much standardization with mil-spec components as possible, and is compatible with most standard AR-15 parts. Five operational parts are proprietary:
- Upper receiver
- Forearm
- Barrel extension
- Gas tube
- Locking lever
We sell these parts to individuals, gunsmiths, and OEMs who want to assemble or turn their own barrels for acceptance into the platform.
None. The platform can be set up as either a folding or a fixed barrel configuration — to fix the barrel, install four mounting screws and remove the pivot pin and locking lever. Added weight from the folding mechanism is negligible, no additional safety concerns exist, and the price is comparable to any quality standard AR. There is no reason not to make the FoldAR platform your new AR standard.

03 / Product improvements
2017 · Origin
The initial pre-production product was licensed to F&D Defense LLC as the XAR Invicta. Machined by East Texas Machining & Manufacturing from billet — nearly indistinguishable from later products made from much stronger 7075-T6 forgings.
2018 · Handguard
Switched from Key-Mod to M-Lok handguard adapter slots.
2019 · Gas system
Upgraded to adjustable gas blocks, and added a paracord pull-lanyard to the locking lever for easier lever and hook disengagement.
2020 · Manufacturing
Upgraded to FoldAR lower receivers manufactured in-house.
2021 · Stock & barrels
Upgraded to the Gen3 Dead Foot Arms MCS folding stock adapter, and expanded in-house barrel manufacturing capability.
2022 · Bolt carrier
After exhausting efforts to source quality BCGs, we moved to the Bootleg, Inc. adjustable bolt carrier group, which outperforms every mil-spec BCG we had used and allows the full range of gas adjustability short barrels and suppressors demand. Forged levers and hook improvements introduced the same year.
2023 · Modularity
Introduced the MoBetta modular barrel systems, allowing hot swaps between barrel length and caliber within seconds. Available barrel lengths expanded across the range.
2024 – 2026 · In progress
