Took my Nova pump tactical to a gunsmith out in Connecticut a few months ago. Drilled and tapped a picatinny rail in front of the rear ghost ring, and used some locktite to secure everything permanently, after drilling down into the metal reinforcement inserts that are underneath all that plastic in the receiver. everything feels incredibly solid and ive been putting it through **** shooting boxes of slugs each week this month. Here are some photos of the Nova with my EOTech 512 mounted on the rail, a UTG shotgun barrel rail clamp, and a Specter Gear buttstock shell holder. went a little overboard on the attachments but for the sake of some photos, why not!
