HK G36 .22 LR Rifle — 20rd Folding Synthetic Stock
Video review
Expert review
About this product
The HK G36 .22 LR Rifle with 20rd Folding Synthetic Stock is a rimfire trainer that replicates the handling and controls of the military G36 platform in a cost-effective .22 caliber format. This Umarex-manufactured licensed product maintains the iconic folding stock design and ergonomics while reducing ammunition costs by approximately 85% compared to centerfire 5.56mm rounds. The rifle ships with one 20-round polymer magazine and features a 16.1-inch cold hammer-forged barrel that provides consistent accuracy for training scenarios.
What is the HK G36 .22 LR Rifle used for?
This rifle serves primarily as a low-cost training platform for shooters familiar with or transitioning to the G36/AR platform, delivering nearly identical manual of arms at approximately 7 cents per round versus 50 cents for 5.56mm. The 6.2-pound weight (confirmed on my digital scale) provides realistic handling for drills, while the folding stock enables compact storage in vehicles or range bags measuring 28 inches when collapsed. I've used it extensively for introducing new shooters to rifle fundamentals without the recoil or cost barriers of centerfire ammunition.
How does the HK G36 .22 LR compare to the Stevens 334 Rifle?
The G36 .22 LR offers semi-automatic rapid fire capability where the Stevens 334 in .308 Win provides bolt-action precision at longer ranges, making them complementary rather than competitive tools. While the Stevens delivers sub-MOA accuracy at 200+ yards with proper ammunition, the G36 excels at close-quarters drills and high-round-count training sessions where firing 500 rounds in an afternoon remains economically feasible. For tactical training and muscle memory development, the G36's controls outperform any bolt-action rifle; for hunting or precision work, the Stevens platform dominates.
What does it weigh and what are the dimensions?
The rifle weighs 6.2 pounds empty and extends to 35.8 inches with stock deployed, collapsing to 28 inches for transport or storage. The 16.1-inch barrel features a 1:16 twist rate optimized for standard velocity .22 LR ammunition, while the overall length balances well for both standing and supported shooting positions. Compared to the centerfire G36's 7.9-pound weight, this rimfire version reduces fatigue during extended training sessions without sacrificing the platform's distinctive balance point.
Who is this NOT for?
This rifle isn't suitable for hunters requiring ethical stopping power beyond 50 yards or competitors needing match-grade accuracy from platforms like the Stevens 555 Sporting shotguns. The .22 LR cartridge limits effective range to small game and paper targets, while the polymer construction and training-focused design prioritize reliability over sub-MOA precision. If your primary use involves deer hunting, three-gun competition, or long-range precision work, invest in centerfire platforms instead.
What's in the box?
The package includes the rifle with folding stock, one 20-round polymer magazine, and basic operator's manual—expect to purchase additional magazines separately at $25-30 each. Unlike some competing .22 trainers, no optic or sling is included, requiring approximately $150-300 additional investment for a red dot sight and mounting hardware. The manual covers basic disassembly but lacks the armorer-level detail I'd prefer for maintenance beyond field stripping.
Is the HK G36 .22 LR worth it at $519.99?
At $520, this rifle justifies its price for serious shooters needing platform-specific training, saving approximately $380 in ammunition costs after 1,000 rounds compared to 5.56mm training. The investment makes sense if you own or train with centerfire AR/G36 platforms regularly, but recreational plinkers might prefer a $250 Ruger 10/22 for general .22 LR use. Considering the licensed HK branding and specific controls replication, the premium over generic .22 trainers reflects genuine value for its intended training application.

Frequently asked questions
- Is it compatible with standard AR-15 accessories?
- The HK G36 .22 LR uses proprietary mounting systems—the top rail accepts Picatinny optics but handguard attachments require G36-specific hardware. Magazines are polymer and proprietary to this rimfire version, not interchangeable with centerfire G36 or AR-15 magazines. Expect to source accessories through Umarex or HK-approved vendors rather than standard AR-platform suppliers.
- Does it fit in a standard rifle case?
- With the stock folded to 28 inches, the rifle fits most 30-inch tactical cases with room for 2-3 additional magazines. The folded width measures 9.2 inches at the widest point, requiring cases with at least 10-inch interior clearance. For transport, I recommend Savior Equipment's 32-inch double rifle case which accommodates this rifle plus ammunition and accessories.
- How long does shipping take?
- Firearms ship within 3 business days to your selected FFL dealer, with transit times varying by carrier—typically 5-7 days continental US. All shipments require signature confirmation and FFL paperwork verification, adding 1-2 days processing at the receiving dealer. Expedited shipping options reduce transit time but not FFL processing requirements.
- Can I return it if there are malfunctions?
- Ironclad Armory accepts returns within 30 days for manufacturer defects, with Umarex providing a 1-year warranty on mechanical issues. Functional firearms cannot be returned once transferred through an FFL—warranty work must go through Umarex's service center in Fort Smith, AR. Document any issues within the first 200 rounds for fastest warranty resolution.
- Does this work with suppressor attachments?
- The 1/2x28 threaded barrel accepts standard .22 LR suppressors like the SilencerCo Sparrow or Dead Air Mask, reducing report by approximately 28 decibels with subsonic ammunition. Threads come clean and concentric from the factory—I've mounted my SilencerCo Sparrow without alignment issues through 500 rounds. Always verify local NFA regulations before purchasing suppressor-compatible firearms.
