What muzzle break is that?Just gave my MS a 500 round workout. And everything looks perfect still. No weird gouges or uneven wear . The only issue I ran into is my Adjustable gas block is useless with my setup as it ran wide open.

You should also check out the unfortunately named but excellent APA CHODE single port.
I have a Modern Sporter SS coming soon on the 2nd run. It will probably be my only NR sporter. What would you recommend to install the barrel. Dont want to buy a tool that I mite use only once or maybe twice. I have a wheeler kit and have built a Restricted AR15. A Magpul Bev-block?
Thanks

So I have the exact same BCG and asked around a lot about using an adjustable gas block or not. Overall I got chided for suggesting that I wasn't going to use adjustable, so this is very good to see. Thanks for posting.

A vise block will help you in seating a tight barrel extension when you aren't able to use the reaction rod.
As someone who hasn't purchased one yet but is looking over the fence, are we really worried about torquing with a vise block and tweaking/distorting a billet 7075 MS upper?

Hey guys, second post on CGN - I joined for this build thread and the photo thread. I still have a while to wait for my receiver set but here’s my build list. First time building an AR from scratch so if I am missing anything or you see something that won’t work, please let me know. This will be primarily a 3 gun rifle but with the option to take hunting for small game and/or some medium range target shooting from a bench.
Upper:
MRA V1 match barrel - 18.6”, SPR straight flute
MRA V1 handguard - 15” FDE
MRA rock solid brake
Superlative Arms adjustable gas block - 0.750” clamp on
Rifle length gas tube
Radian raptor SL charging handle
Brownells lightweight BCG
generic dust cover
Lower:
JP silent captured spring
Timney calvin elite trigger
Magpul K2+ grip FDE
MRA 45deg ambi safety
Geissele maritime bolt release
Norgon ambi mag release
generic lower parts kit
generic mil spec buffer tube and castle nut
Magpul endplate with QD
Magpul CTR stock - interested in the B5 sopmod as well but not sure how different the colour is from the magpul FDE

Welcome to CGN!! I’m also waiting quite a while for my set and it will be my first Ar style build as well. That sounds like a nice setup you have there. I don’t see anything missing from that list, looks good to me!

Looks like a good build. My personal preference for a ambi magazine release is the Troy Industries one. The button is quite a bit bigger and I find easier to use.

I actually haven't tried a Troy ambi magazine release on my ATRS MS. I run it on a couple of my AR's and they do drop free from my AR's. Give me a few days to get home from work and I'll swap one into my ATRS MS to see if it functions.
Hey guys
I’m getting some parts together for my MS build. I was wanting to go with a JP enterprise BCG with their enhanced bolt. And was going to try a Vltor Buffer System to go with my 18.6” BSF barrel. Has anyone tried either of these or heard of any issues?
