Redweirdbeard Posted June 14, 2019 Share Posted June 14, 2019 Thinking about sending off my M4 to have it coated with their np3 or maybe np3+. I know some of you have had it done and was curious at how it's hold up. Thanks Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted June 14, 2019 Share Posted June 14, 2019 Excellent process. The Weapon will feel and sound completely different once done. Very little if any tolerance stacking issues with NP3. The recoil impulse is different. Like the recoil isn’t as sharp. Some who who have had Robar do their disassembly and reassembly have not been completely happy with the results. Many items are skipped since they’re a PITA to get apart. Items such as the bolt. You’ll want all your aftermarket accessories plated along with the shotgun for cosmetics The process is super expensive. You can count on around 900-1000 dollars by the time you do the chemical stripping and shipping costs. The process takes along time. I typically see 9-15 weeks for parts to return. 1 Quote Link to comment Share on other sites More sharing options...
Redweirdbeard Posted June 14, 2019 Author Share Posted June 14, 2019 How do you feel about just having the bcg coated since these like to run wet. Do you think that would help with the lubrication? Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted June 14, 2019 Share Posted June 14, 2019 (edited) I’ve done that too. There are a host of parts that benefit the cycling. You can run lighter loads trouble free when the plating is done. The M4 doesn’t show much for corrosion unlike a lot of other shotguns out there. So the main benefit to Np3 is going to be the lubrications and resistance to failure aspect. One of mine I don’t even bother cleaning. I just squirt more oil in and it is good to go. Adding more oil probably isn’t even necessary. That M4 has well over 18,000 rounds thru it. I think I’ve been up around 4000 before I feel bad enough to clean it. Biggest benefit to cycling to least for plating; Bolt Carrier Receiver Extension Receiver Receiver extension Plunger Hammer Bolt Carrier Link Bolt Head Pistons Magazine Follower Magazine Tube Firing Pin BCG cam pin BCG link pin Bolt Breech Lever Bolt Breech Lever Pin Breech Latch Plunger Aluminum trigger frame Hammer Bushing Shell Elevator Shell release lever Disconnector Plunger Bolt Release Lever Bolt Release Lever Pin Tearing apart things like the ARGO plugs is doable and make it easier to clean. You won’t see much performance improvement though. When buying say a trigger pack from FFT, the components are already plated in Np3. You don’t have to risk messing plating ground surfaces. I made a jig to polish the interior of the magazine tubes after plating. It’s basically a big cleaning rod for shotguns that has fine steel wool on it. It’s then run thru it for 10 minutes or so to bring the interior to a polished mirror surface.
