If you’ve been looking for a high-quality billet upper receiver, rest assured that your search is over. The IRMT-3 v3 upper by Seekins Precision is designed to meet the rigorous requirements of today’s AR-15 owner.
This upper includes the Seekins-exclusive Integrated Rail Mounting Technology (IRMT) in its design. IRMT seamlessly integrates the rail directly into the upper itself, thereby creating a true monolithic upper with the strength called for among the accessory-laden rifles of today. The ability to change rail systems when desired permits maximum customization opportunities.
The IRMT system accepts the externally-threaded titanium barrel nut from SP3R V3 Rails for ease of installation and eliminates the need for special wrenches. This AR15 upper will arrive with a pre-installed dust door and forward assist to allow you to continue with your assembly or replacement as quickly as possible.
As the owner of an AR-15, you understand the responsibility you bear to ensure that your rifle is in the best of conditions at all times. Should an urgent need arise, you won’t want to be caught struggling with a malfunctioning weapon because you purchased cheap parts. The Seekins brand has proven itself over and over again to be worthy of gun owners’ trust. Order your billet upper receiver today!
