Here’s the thing—at $1238.35, this rifle sits in a sweet spot between budget builds and high-end custom varminters. You’re getting a complete, ready-to-shoot system from a manufacturer with a proven legacy (the original Bushmaster team). The weight, coming in around 9-10 lbs unloaded, is a practical tradeoff. That heft, centered on the heavy barrel, makes it a steady platform but less ideal for long carries across fields.
Who This Rifle Is For
This rifle is built for the practical shooter who needs consistent, small-group accuracy without a four-figure custom gunsmith bill. It’s ideal for Missouri varmint hunters targeting groundhogs or coyotes from a fixed position, or for a new shooter wanting a dedicated, drop-in ready rifle for learning precision fundamentals. The fixed stock design also makes it a straightforward option for states with specific compliance requirements.
Pros & Cons
Pros: The value is undeniable—you get a specialized barrel and premium adjustable stock in one package. Windham’s reputation for quality control means it should fit and function out of the box. The Luth-AR stock offers serious ergonomic adjustment typically found on rifles costing hundreds more. It’s a simple, effective tool that ships to Missouri and compliant US states.
Cons: The fixed stock isn’t for everyone; if you need a compact, collapsible carbine for dynamic use, look elsewhere. The weight can be a burden for stalking. And while the single 5-round mag is fine for its role, you’ll likely want to invest in additional standard-capacity PMAGs or Lancers for the range.
Frequently Asked Questions
Q: Is the barrel chambered for .223 or 5.56?
A: It’s dual-chambered, so you can safely fire both .223 Remington and 5.56x45mm NATO ammunition, giving you flexibility in ammo selection based on price and purpose.
Q: Can I use my existing AR-15 magazines with this rifle?
A: Absolutely. The lower receiver is mil-spec and works with standard AR-15 lowers and magazines from brands like Magpul PMAG and Hexmag, so you can use any compliant magazines you already own.
Q: Is the cheek piece on the Luth-AR stock easy to adjust?
A: Yes, it uses a simple, tool-less knob system to raise and lower the cheek rest, and a separate adjustment for the length of pull. You can dial in a perfect weld in seconds, lock it down, and have a consistent fit every time you shoulder the rifle.
If you need a dedicated, accurate rifle that delivers serious bang-for-your-buck right out of the case, the Windham Weaponry R20 Varmint is a compelling choice. See full details and availability at firearms-missouri.com for Missouri residents and nationwide.
