DEZ Tactical Arms

Description:

The DEZ Tactical Arms front sight base is of the highest quality available. This clamp-on front sight mounts easily and securely with 5 sets screws - no drilling or taper pins required! This "F-height" front sight is a perfect match for your standard height rear sight, whether you decide to go with flip-ups or a removable carry handle. Made from tough cast steel, and protected by an ultra durable coating. This front sight will fit on any standard barrel that is .750" in diameter. Sight includes bayonet lug mount and set screws for mounting.

The F-height front sight base is designed to be installed on builds with an A3/4 "flat-top" upper receiver. This sight measures 0.040" higher than standard (non F-height front sight bases). Can also be installed on builds with an A2 or A1 upper receiver, given the proper adjustments are made during the zero of your firearm.

The following parts are included in this assembly:

• 1 - Front Sight Base - Set Screw Mount .750" F-Height
• 5 - 8-32 x 1/8" Set Screws
• 1 - Gas Tube Roll Pin

Note: A 5/64" hex wrench is required for installing set screws. Base price does not include front sight parts (sight post, detent, spring), or sling swivel & rivet - Search SKU DEZ-1035-GB for complete assembly.

Please be advised: If your barrel has been previously drilled for tapered pins, this part may not mount correctly to your barrel. This gas block attaches directly to the barrel with 5 set screws.

Important: You will need to remove the muzzle device and your pre-existing gas block and gas tube before installing this
Front Sight Base. Installing the new Front Sight Base is fairly simple for anyone with a basic understanding of the AR-15
and familiarity using tools, although it is recommended that the installation of this sight be completed by a qualified
gunsmith. Follow the instructions below for installation:

Installation Instructions:
1. Turn your upper assembly 180 degrees/upside-down (best done by fixturing in a vise with a top rail picatinny clamp,
or soft jaws as to not damage the finish). When you vise it in, use a bubble level on the underside of your upper receiver
and confirm that it is level
2. Slide the Front Sight Base over your barrel up against the barrel shoulder. Using a bubble level, level the underside of
the Front Sight Bayonet lug with the underside of your Upper Receiver
3. Attach the front sight to your barrel with the included 5-set screws, using removable thread-locking fluid on the set
screws
          Although not required, it's strongly recommended that you divot the underside of the barrel with a drill bit
             (where the bottom set screw is located) to ensure that the sight does not move if the rifle is ever dropped, or
             the sight were to get directly hit against another object
4. Install Front Sight Hardware (Sight Post, Detent, Spring & (Optional) Sling Swivel)
             It is recommended that you install the Front Sight Hardware with a 4-Prong Sight Tool (One is offered by UTG -
                Item #: SCP-FTA24). The tool is cost effective and very useful for making elevation adjustments in the field
            If you choose to attach the Sling Swivel, it will need to be attached with the included rivet. There are tools
               available for properly staking the sling swivel rivet, although other methods of staking may be more cost
               effective for "one-time" jobs
5. Re-attach Gas Tube into Front Sight Base with Gas Tube Roll Pin
6. Re-attach Muzzle Device
Note: It is advised that you install this Front Sight Base on a barrel that has not been drilled for taper pins. If your barrel
has already been drilled with tapered pins for your pre-existing gas block, it is possible for the set screws to not seat
properly on the barrel. If your current gas block is attached with set screws, you will not have any issues attaching this Front Sight Base to your pre-existing barrel.
