A comparison of the Double Eagle N4 and N4 NSR-SD GBB rifles as done by the 6mm Badger... "In today’s video I’m doing a full side-by-side comparison between two of Double Eagle’s most popular gas-blowback rifles — the original N4 and the new N4 NSR-SD.

The standard Double Eagle N4 has been around for a while now and built a reputation as one of the best-value MWS-based GBBRs on the market. I’ve owned mine for a long time, upgraded it, and even swapped out the bolt — but it’s been sitting on the wall for ages.

The new N4 NSR-SD, on the other hand, has completely surprised me. With its integrally suppressed handguard, built-in eShooter tracer unit, and updated Noveske-licensed design, it feels premium straight out of the box. For only about $50 more than the original model, it’s a seriously good deal.

Price Comparison:

• Double Eagle N4: $350
• Double Eagle N4 NSR-SD: $400 (includes integrated tracer unit + thicker rail)

In this video I cover:

• Design & spec differences between both replicas
• Performance & chronograph testing
• Feeding reliability (especially with aftermarket bolts)
• FPS comparison between Double Eagle and Guns Modify magazines
• My final thoughts on why I prefer the NSR-SD overall"
