Keystone Thread Adapter Features The Keystone Sporting Arms Thread Adapter bridges the 3/8x24 and 1/2x28 thread patterns letting Crickett rifle owners mount accessories that would otherwise not thread onto the rifle directly. This kind of adapter is especially useful when a scope mount sight or other accessory is designed around a thread standard that differs from the Crickett s factory threading. Rather than requiring a gunsmith to re-thread a component the adapter handles the conversion in a single small part. At 7.6 inches overall it is sized to fit cleanly into the Crickett s accessory footprint without adding bulk. Finished in blue the adapter is built as part of Keystone s Crickett Series accessory lineup reflecting the attention Keystone puts into supporting its youth and compact rifle platform with purpose made parts. Weighing only about 0.05 pounds it is light enough to install and forget with no noticeable impact on the rifle s balance or handling. Because it is designed specifically for the Crickett fitment is straightforward without modification. For Crickett owners needing a dependable way to match mismatched accessory threads this adapter is available for sale at GrabAGun.
