Frequently Asked Questions

What is the most cost-effective upper receiver for a budget SPR build?

For a budget SPR build under $400, the Bear Creek Arsenal (BCA) 18-inch or 20-inch .223 Wylde stainless steel upper assemblies are highly recommended. They offer exceptional accuracy for their price, often costing around $210, and are known to perform well.

Can a sub-$400 SPR build achieve sub-MOA accuracy?

Yes, a sub-$400 SPR build can achieve sub-MOA accuracy. This video demonstrates this by showcasing 100-yard groups under 1 inch, including a notable 0.52-inch group and a 3-shot 'same-hole' group, using carefully selected budget components.

What ammunition performs well in budget SPR builds?

Surprisingly good performance can be achieved with budget ammunition. Callaway Ballistics .223 Rem 55gr FMJ remanufactured ammunition, for instance, produced match-grade groups in the tested barrel, proving that cost-effective ammo can yield excellent results.
