I wouldn't expect any of these "upgrades" to have any affect on accuracy, unless you're shooting in heavy rain.

 

I’ve never put an EBR together but here’s what I know:

to my knowledge the NM FS is bored out slightly to keep rain from interfering with the round in matches, so no real advantage I know of. My best rifle shoots sub moa and it has standard FS

bayo lug does not affect accuracy

the NM pistons are hit or miss between individual rifles, some people just say to try a few different ones and see which one works best. I’ve heard of some rifles negatively affected by using NM pistons with the groove because it affects gas,, but the coating supposedly makes cleaning easier.

you’re already sinking a chunk of change in an EBR so why not try it with all your existing parts and see what shakes when you get it in the chassis?

just my opinions

Thanks for the insight. I don’t think I’ll swap out the gas piston then as the standard one works. I was curious about the SEI piston that they say were installed on EBRs/EMRs. Didn’t say they were NM, so not sure.

 

Here’s my answers.
1. Yes.
2. No
3. Maybe. If ease of cleaning is the goal. Accuracy impact can only be tested via trial and error.

 

Thanks everyone. I guess if I upgrade it would just be to the NM flash hider with bayonet lug.

 

For the cost of the chassis, I can build 2 more rifles. 😁

No doubt the rifle looks ungodly mean. But the wood instills certain decorum to the rifle itself. I just love the look in its original wood. No fuss. No muss. Simple and effective as it was intended.
