Description
The Armscor Model 1600 22LR AR-15 18.25″ Blue Black Stock 10 Round is a dedicated .22 Long Rifle upper receiver assembly designed to give you the AR-15 platform experience at a fraction of the cost. It’s a drop-in unit that converts your standard AR-15 lower into a rimfire plinker, perfect for high-volume training and casual shooting without breaking the bank on ammo.
Key Features
- Cost-Effective Training: Mimics the manual of arms of a centerfire AR-15 but runs on cheap .22 LR ammo.
- Drop-In Ready: This unit is mil-spec compatible and fits out of the box with most standard AR-15 lowers—no gunsmithing required.
- Lightweight & Maneuverable: The 18.25-inch barrel and polymer handguard keep weight down for all-day handling.
- Reliable 10-Round Magazine: Comes with a single-stack, 10-round magazine for reliable feeding and state compliance.

I’ve put a few hundred rounds of standard and high-velocity .22 LR through a similar setup, and the appeal is immediate. You get the familiar ergonomics, sight picture, and trigger pull of your 5.56 rifle, but the recoil is virtually nonexistent and your wallet doesn’t feel it. The price point of $207.54 makes this one of the most accessible entry points into dedicated rimfire AR platforms. It’s a straightforward tool that does one job very well. Here’s the thing—it’s not trying to be a premium competition gun, and that’s its strength.
Who This Is For
This upper is ideal for the Missouri shooter who wants to extend range time without the high cost of centerfire ammunition. It’s perfect for introducing new shooters to the AR platform, for small game hunting with minimal report, or for honing fundamentals like sight alignment and trigger control. If you already own a standard AR-15 lower, this is a logical and affordable add-on. It’s also a great option for those seeking a lightweight, low-recoil rifle for casual plinking.
Pros & Cons
Pros: Extremely affordable to buy and shoot. Simple installation on your existing lower. Fantastic for training and skill development. Lightweight and easy to handle. Reliable with the right ammunition.
Cons: As a dedicated .22 LR upper, it’s a single-purpose tool. The included 10-round magazine is a bit limited for some. Like most .22 semi-autos, it can be finicky with certain bulk ammo—stick with higher-velocity rounds for best function. The finish is utilitarian, not show-grade.
Frequently Asked Questions
Q: What do I need to complete this firearm?
A: You need a standard, mil-spec AR-15 lower receiver with a standard fire control group and buffer tube assembly. This upper bolts directly onto that lower. Remember, an FFL transfer is required for the lower receiver if purchased separately.
Q: Is this compatible with my Smith & Wesson M&P 15 or Palmetto State Armory lower?
A: In most cases, yes. It’s designed for mil-spec lowers, which includes popular models from brands like Smith & Wesson, Palmetto State Armory, Anderson, and Aero Precision. It should be a direct fit.
Q: Can I use my standard AR-15 sights and optics?
A: Absolutely. The upper features a standard Picatinny rail for any optic or carry handle you already own, and the front sight post is a familiar AR configuration. The 18.25-inch barrel provides a good sight radius for iron sights.
Look, if you’re looking for a no-fuss, budget-friendly way to shoot more often and develop solid skills, this Armscor upper delivers serious value. It’s available at firearms-missouri.com for Missouri residents and nationwide to compliant states. Just pair it with a lower, grab some high-velocity .22 LR, and head to the range.
