H&K MP5 Rifle .22 LR — 16.1in Barrel
About this product
What is the H&K MP5 Rifle .22 LR — 16.1in Barrel? It's an HK-authorized, semi-automatic .22 LR rimfire rifle built by Umarex in Germany that replicates the classic MP5 platform with a 16.1-inch steel barrel and metal receiver. This rifle delivers authentic MP5 ergonomics and controls while using economical rimfire ammunition, making it ideal for training and recreational shooting without the cost and recoil of centerfire cartridges.
What is the H&K MP5 Rifle .22 LR used for?
This rifle is designed for sub-caliber familiarity training, plinking, and introductory shooting on the MP5 platform. It mirrors the manual of arms, sight picture, and controls of the original MP5, allowing users to practice drills and manipulations with affordable .22 LR ammunition. The blowback operation and 16.1-inch barrel ensure reliable cycling and consistent accuracy at typical rimfire distances.
How does the H&K MP5 Rifle .22 LR compare to the Stevens 334 Rifle?
The H&K MP5 Rifle .22 LR is superior for tactical-style training and rapid fire, while the Stevens 334 Rifle in .308 Win excels at precision and hunting applications. The MP5 .22 LR offers semi-automatic fire, a 25-round magazine capacity, and MP5-specific ergonomics, whereas the Stevens 334 is a bolt-action rifle with a 20-inch barrel and 4-round internal magazine built for accuracy at longer ranges. For shooters focused on platform familiarity or high-volume practice, the MP5 .22 LR is the better choice; for those needing power and precision, the Stevens 334 dominates.
What does it weigh and what are the dimensions?
The rifle weighs 6.2 pounds unloaded and measures 28.5 inches overall with the stock retracted. With the stock extended, the length increases to 34.75 inches, providing an adjustable length of pull from 12.5 to 14 inches. The 16.1-inch steel barrel contributes to the weight and balance, closely matching the feel of the original MP5.
Who is this NOT for?
This rifle is not for hunters or shooters requiring centerfire power or long-range precision. The .22 LR cartridge limits effective range to approximately 100 yards, and the blowback operation lacks the recoil impulse of a locked-breech system. Those seeking a dedicated hunting rifle should consider the Stevens 334 in .243 Win, which offers greater energy and accuracy beyond 200 yards.
What's in the box?
The package includes the rifle, one 25-round polymer magazine, and an owner's manual. No optics, sling, or cleaning kit is provided, so buyers should budget for additional accessories. The manual covers basic operation, maintenance, and safety procedures specific to this rimfire variant.
Is the H&K MP5 Rifle .22 LR worth it at $547.99?
At $547.99, this rifle is justified for shooters dedicated to MP5 platform training or seeking a high-quality .22 LR replica. The HK authorization, metal receiver, and functional retractable stock add value over cheaper .22 LR alternatives. However, for general plinking or introductory shooting, less expensive rimfire rifles may suffice, making this a niche investment.

Frequently asked questions
- Is it compatible with standard MP5 accessories?
- No, it is not compatible with most standard MP5 accessories due to its .22 LR design and Umarex-specific dimensions. The faux suppressor is integral and non-removable, and the rail system differs from MIL-STD-1913 patterns. Accessories must be verified for Umarex MP5 .22 LR compatibility.
- Does it fit in a standard rifle case?
- Yes, with the stock retracted to 28.5 inches, it fits most 30-inch rifle cases. A case like the Plano All-Weather 36-inch model provides additional room for magazines and accessories. Always measure your case interior to confirm clearance.
- How long does shipping take?
- Shipping typically takes 3-7 business days for in-stock items, depending on your location and carrier. Ironclad Armory processes orders within 24 hours on business days. Expedited options are available at checkout for faster delivery.
- Can I return it if it doesn't fit?
- Yes, returns are accepted within 30 days of purchase for unused items in original packaging. A restocking fee of 15% applies if the firearm has been fired or accessories missing. Contact Ironclad Armory support to initiate a return.
- Does this work with a suppressor?
- No, the barrel is not threaded for suppressor attachment, and the faux suppressor is permanently attached. Attempting to modify it voids the warranty and may violate NFA regulations. For suppressed .22 LR shooting, consider a dedicated threaded rifle.
