Description
The Windham Weaponry A4 308 Flat Top 16.5 10rd Ca is a budget-conscious, California-compliant AR-10 platform rifle chambered in .308 Winchester/7.62x51mm NATO. It features a 16.5-inch barrel, a flat-top receiver for optics, and a fixed 10-round magazine to meet specific state regulations, offering a robust semi-automatic platform for hunters and sport shooters at a practical price point.
Key Features & Value Proposition
- Flat-Top Upper Receiver: Provides a clean, uninterrupted Picatinny rail for mounting optics, scopes, or backup iron sights without a carry handle, giving you a modern sighting platform.
- 16.5-Inch Barrel in .308: Balances maneuverability with the potent ballistics of the .308 round. It’s a handy length for hunting in brush or moving through a vehicle, though you do trade some velocity compared to a 20-inch barrel—a classic value tradeoff.
- California-Compliant Configuration: Comes from the factory with a fixed 10-round magazine, making it ready for compliant states right out of the box. This saves you the hassle and potential cost of modifying a standard rifle later.
- Windham Weaponry Build Quality: Built by the original Bushmaster team in Maine, these rifles are known for reliable mil-spec compatibility and solid construction without the premium brand-name tax.

Weighing in at roughly 8.5 pounds unloaded, this rifle has a solid, substantial feel that helps manage .308 recoil. The heart of the value here is the $1163.99 price tag. When you stack that against other factory-built AR-10s, Windham often undercuts the competition by a couple hundred dollars, putting a capable .308 platform within reach for more shooters. Remember, an FFL transfer is required for firearm purchases, a standard step we handle seamlessly.
Who This Rifle Is For
This is a practical tool for the budget-aware shooter who needs a compliant rifle from day one. It’s ideal for hunters in dense timber where the 16.5-inch barrel is an advantage, or for sport shooters wanting a versatile .308 for medium-range target work without breaking the bank. It also serves as a straightforward foundation for a build if you want to upgrade components like the handguard or stock later, as it’s compatible with many DPMS-pattern AR-10 parts and accessories.
Pros & Cons: The Honest Tradeoffs
Pros: The biggest pro is the out-of-the-box compliance for restricted states, eliminating guesswork. You get Windham’s reputation for reliable, no-frills function. The flat-top receiver offers maximum optic mounting flexibility. And let’s be real—the price is the main attraction, offering serious bang-for-buck in the large-frame AR market.
Cons: The fixed 10-round magazine is a limitation for some, though it’s the cost of compliance. The 16.5-inch barrel sacrifices some muzzle velocity, which long-range precision shooters might mind. It’s also not the lightest rifle, but that weight soaks up recoil. You’re getting a workhorse, not a lightweight race gun.
Frequently Asked Questions
Q: Is the magazine truly non-removable?
A: Yes, as configured for compliance, the magazine is fixed in place. Reloading is done via stripper clips or by opening the bolt catch, which is the standard method for this type of compliant firearm.
Q: Can I use PMAGs or other AR-10 magazines with this rifle?
A: The lower receiver is designed for standard SR-25/DPMS pattern magazines. However, in its compliant configuration, the fixed magazine assembly must be legally modified or replaced by a qualified gunsmith to accept detachable mags, which may affect its compliance status depending on your local laws.
Q: What kind of optic rail does the flat-top receiver have?
A: It features a full-length Picatinny rail, mil-spec compatible with virtually any modern optic mount, red dot sight, or scope rings. This is a drop-in ready platform for your preferred sighting system.
