If you like guns, then the odds are, you like knives as well. Every gun person is also a knife person, especially those at Daniel Defense. The Daniel Defense Big Hole Flat Top Upper is designed and built with a .315 front pin hole to fit the early Colt lowers with .315 front holes. This eliminates the need to use an offset pin, which requires 2 screwdrivers during assembly/disassembly of these rifles. This upper comes with our .315 Push Pin, which makes the assembly/disassembly of the upper and lower quick and easy. It has a detent ball to hold the pin securely in place. This upper comes complete with forward assist, ejection port cover Indexing Marks and M4 Feed Ramps.
