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.

I recomend this to anyone with the old big hole Colt, upgrade to the A4 configuration with no modificationsI've been looking for this option for my old Colt A2 HBAR for years
fits like a glove, no rattle or movement. Has the M4 ramps to match the new barrel I ordered
