Frequently Asked Questions

How accurate is the BoreBuddy .22LR match grade upper?

During testing on an outdoor shooting range, the BoreBuddy .22LR match grade upper demonstrated sub-MOA accuracy, with group sizes ranging from approximately 0.722 to 1.152 MOA at 100 yards. This level of precision makes it a high-performance option for the AR-15 platform.

What is the difference between a dedicated .22LR upper and a conversion kit?

A dedicated .22LR upper, like the BoreBuddy Match Grade Upper, is purpose-built for rimfire cartridges and designed for optimal accuracy. A conversion kit typically uses a standard 5.56 NATO/.223 Remington upper and inserts a .22LR barrel insert and bolt, generally resulting in less consistent and less precise accuracy.

What tools are needed to test the accuracy of a firearm upper?

To test firearm upper accuracy effectively, tools like the BoreBuddy Match Grade Upper, an AR-15 platform, a reliable optic (e.g., Holosun red dot), and a target analysis system such as Ballistic-X are recommended for precise measurement and documentation.

What accuracy can be expected from an AR-15 with a .22LR conversion kit?

When using a standard .22LR conversion kit in an AR-15 platform, accuracy is generally less consistent and precise compared to a dedicated match grade upper. Testing showed significantly larger and less predictable groups than the sub-MOA performance achieved with the BoreBuddy match upper.
