Frequently Asked Questions

What makes the 25-45 Sharps caliber unique for an AR-15?

The 25-45 Sharps caliber uses a heavier 25-caliber bullet (87 grains) compared to the standard 5.56 NATO (55 grains). This allows it to carry more energy at longer distances, making it suitable for hunting larger game while still being compatible with standard AR-15 components through a simple barrel swap.

How do you convert an AR-15 to the 25-45 Sharps caliber?

Converting an AR-15 to the 25-45 Sharps caliber is straightforward. Since the parent case is the 223/5.56, you only need to replace the barrel. The bolt carrier group, bolt, and magazines remain the same as those used for 223/5.56 ammunition.

What are the claimed advantages of the 25-45 Sharps over 5.56 NATO?

The primary advantage claimed for the 25-45 Sharps is its significantly heavier projectile (87 grains vs. 55 grains) which translates to higher energy transfer, especially at longer ranges (300-400 yards). This makes it a more potent round for hunting and potentially for tactical applications where increased impact is desired.

What specific features does the Sharps Rifle Company AR-15 have?

The reviewed SRC AR-15 features a 'Reliaguard' bolt made from S7 tool steel for durability, a balanced bolt carrier, and both are finished with an electroless nickel-based plating for slickness and ease of cleaning. It also utilizes a 20-inch heavy barrel and an effective muzzle brake.
