I am currently building a M4A1 Block 2 clone. I am deciding between Knights NT4 vs Surefire SOCOM RC(2), both are clone correct from what I’ve gathered. Does anyone have experience with either or both? Which one would you choose?
Surefire is cheaper, lighter, better muzzle devices, and just as tough as the NT4. I would choose the SF every time over the NT4 especially if its going on a M4A1.
Surefire every time. I’ve used both cans on Mil rifles. All the reasons Furbyballer mentioned. NT4 is crazy durable, but outdated and heavy. I don’t remember noticing a significant difference in attenuation, but the Surefire is lighter and has a better mount.
Surefire, as said above. Neither are quiet cans, but they are insanely durable and do a good job at total signature reduction. My experience comes from the .mil issued units and I would select Surefire because of their current technology, weight, and selection of muzzle devices.
I’ll take the nt4 because I dont have to deal with the can getting carbon locked on.
NT4 can be a bear to remove, also.

Is what you seek

If people choose Surefire RC2 over NT4 for a block 2 clone, is is the same answer for a can going an a 16" SR15? How about an 11/5" SR15?
Yes. But the mini
A mini NT4 would be cool and if I recall they prototyped one

I remember Jack talking about a NT3, same as the 4 but 3 baffles instead of 4.
Yup that was it.
Would be cool if it existed. But didn’t cost 1500

I’ve never seen a picture of an RC2 in service. I’ve only seen RC.
Thanks everyone for the input. Surefire it is.

Here you go… I voted surefire. I have a KAC QD762 that I love. But I’m waiting for a RC2 762 to clear jail because I like the Surefire more.
Esp. if you use a mount like PWS that doesnt have the ramp cut into it.
I have 3 NT4s…If I was to do it all over again it would be SF RC…find a golden ticket and grab one.
Why is that, Im happy with all the cans I own and run. Hard to hate on KAC stuff.

My point was I have never seen an RC2 in US military service and I don’t know if the RC2 was ever adopted.
Last time I looked into this the RC was still the standard.
Now THAT is something you will RARELY hear/read/say. :lol:
