SEEKINS SELECT ADJ GAS BLOCK .750

The addition of a suppressor, dirty conditions or even switching ammo are all factors that can lead to undesirable gas settings on your rifle. Our patent pending design was initially developed to fulfill an order in our Government programs which required the ability to run suppressed or unsuppressed in the field.

Features:

• 40 position fine adjustment
• Tool-less gas selection switch
• Suppressed or unsuppressed
• Melonite coated tool steel
• Available in .750 and .875 DIA
