Description
If you run a Browning A-Bolt 12 gauge slug gun and want a dependable platform to hang glass on, this EGW Picatinny rail is about as straightforward as it gets. It bolts right to your receiver's factory scope holes, so there's no drilling or tapping involved. EGW machines these in-house from domestic 6061-T6 extruded aluminum, then tumbles, sandblasts, and Type II anodizes them in a matte black finish that holds up to the recoil a 12 gauge dishes out.
What Sets the A-Bolt 12 Gauge Rail Apart
This is a one-piece design with Picatinny cross slots running the full length of the rail. That gives you real flexibility to slide your rings fore and aft and dial in eye relief exactly where you want it. It accepts any standard Picatinny or Weaver rings, so you're not locked into a single ring brand. A milled center channel trims the overall weight down to about 2 ounces, and in a lot of setups that channel leaves your factory iron sights usable underneath.
The 0 MOA Cant on This A-Bolt Mount
The 0 MOA setup is the one you want for shorter range work, generally inside 500 yards, which covers just about any slug gun application. It keeps your scope's adjustment range centered so you've got plenty of travel both ways when zeroing. The ambidextrous bevel on both sides means it looks clean and works the same whether you're a lefty or a righty.
Fitting Your EGW A-Bolt Scope Rail
Overall length runs 7.064 inches with a center spread of 3.86 inches between the two middle receiver holes. It's a good idea to measure your receiver's hole spacing against those numbers before ordering to confirm the fit. Mounting hardware comes in the box, and EGW recommends torquing the screws to 20 inch pounds with a drop of blue Loctite for a mount that stays put shot after shot.

Frequently Asked Questions
Does the EGW A-Bolt 12 gauge rail require drilling or tapping?
No. It's drilled to line up with the factory scope mount holes on your A-Bolt 12 gauge receiver, so it bolts right on. EGW recommends measuring your receiver's hole spacing against the 3.86 inch center spread to confirm the fit before installing.
What rings work with this Picatinny rail?
It accepts any standard Picatinny or Weaver scope rings since the cross slots run the full length of the rail. That gives you flexibility to position rings and fine-tune eye relief. Rings are not included, so plan to pick up a set that matches your scope tube diameter.
What does the 0 MOA cant mean for this mount?
A 0 MOA rail sits flat with no built-in forward angle, which is ideal for close to mid range shooting out to around 500 yards. That covers just about any slug gun setup. It keeps your scope's elevation adjustment centered with plenty of travel in both directions.
Will this rail let me still use my iron sights?
The milled center channel that reduces weight also leaves the iron sights usable in many setups. Fit can vary depending on your specific sights and scope ring height, so it's worth checking your particular configuration once installed.
