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 all M-14 and M1A rifles. It attaches to the barrel 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 base is the correct height for standard mil-spec or national match M14 front sights such as our SEI night sights and national match sights on a full length, 22" barrel. If using an 18" barrel as on a Springfield Scout, the sight base needs to be a different height so our SEI Gas Lock Sight Base for 18" barrels is recommended. 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.
