SEI M14 Threaded Front Sight Base

SEI M14 Threaded Front Sight Base

This Smith Enterprise Sight Base acts as a thread adapter for M14/M1A type rifles and is a drop-in replacement for the factory front sight base and flash hider assembly on M-14 and M1A rifles. It attaches to the barrel using a castle nut in the same way as the standard front sight base and flash hider assembly, but instead of a flash hider, it is threaded at the front to accept a wide variety of muzzle attachments to include muzzle brakes and flash hiders of different makes and models. This gives you far greater flexibility in using the best muzzle attachment for your requirements. It is threaded with 5/8x24 threads which is the most common .308 cal./7.62mm thread pattern for muzzle brakes and flash hiders. This allows you to mount an extremely wide variety of muzzle brakes and flash suppressors from across the firearms industry to this fine rifle. This part finally lets you put any compensator or flash hider that you really want on your M-14 or M1A

The front sight dovetail is the correct height for standard mil-spec front sights on a 22" barrel. If using an 18" barrel like the Springfield Scout, the sight dovetail height is not correct for a mil-spec M14 front sight.  But if you plan to use the front sight that came on your Springfield Scout, then it will work fine.  If you want to use a mil-spec front sight on an 18" barrel, then you can use our dovetail gas lock for 18" barrel and mount the front sight there. 

This part is made by SEI using 8620 stressproof steel which is EDM machined to exacting tolerances and then hardened for durability under extreme use. Mil-Spec Parkerized Finish.

* Does not include castle nut. Castle nut from factory flash hider can be used.
