In short I bought this Muzzle Brake: http://www. brownells.com/rifle-parts/muzzle-devices/compensators-amp-muzzle-brakes/m14-m1a-muzzle-brake-prod12788.aspx?avs%7cManufacturer_1=SMITH+ENTERPRISE That at the top led me to believe it will work with MY M305 what is the issue because all I can find is that you need to use the M305 Castle Nut and may need to shim or grind down the nut a bit. Would any one know said issue? Or am I going to be looking at selling it?
Smith Enterprises Muzzle brake and M305 Question

I just checked the link you left; (Note: Will NOT fit Norinco/Polytech (M305) with M15x.75 thread.)
SMITH ENTERPRISE - M14/M1A MUZZLE BRAKE

So I guess you either return, sell, or if they changed their add after you bought it call for a replacement/return.

Yah I noticed that disclaimer today but could a gun smith make it fit because the issues I have read about are the castle nut needing to be shimmed or reduced in size but other sites are saying it is the thickness of the threading on some barrels the muzzle brake will not pass over... On guy was griping about the groves being to big on the brake.
I really don't know, outside my scope. 
That said if it was me stuck with it I'd be looking into how I could make it fit. The second link I attached seemed to cover mods like you are suggesting. (I've heard/read everything from using lots of lock-tite to trying to re-thread but have never needed to look into it myself.
I would suggest no matter what you try that you check that the bore lines up properly before you fire it or your likely to shoot off the brake, or worse. You can also try asking in the gunsmithing section...

I have that same brake on my Norc. it installed without issue using the Norc castle nut.
Mine is an older rifle that did not have the welded flash hider; I do not know what the thread pitch is on my rifle.
I see no reason why a gunsmith could not make it work for you if you encountered difficulties with the installation.

I believe it is just the castle nut they say wont fit as it is a different thread pitch , I have seen lots of these on Norincos...They need to have the 3 splines cut in the barrel is all and they are a great muzzle brake !
Ok so all the reading about minor if any mods to the castle nut is all I should worry about... I have read a few people say they need to sand the texturing off of their nut and one guy need to shim his to get it to fit all very minor issues. From what I understand getting the flash hider off is a bigger issue
Get a good punch and a big hammer and unscrew the allen screw for the castlenut on the front of the sight and back off the nut a bit . ....put the punch on the sight base/bayo lug and don't be scared to hit it hard .Once the spot welds break keep backing off the castle nut and tap off the flashider. I have taken off lots like this and only one broke around the spot welds but the flashider was still useable.
I don't know what issue is being experienced or anticipated, perhaps you can explain more. I have had one of these SEI muzzle brakes on my Norc and it fit fine just using the pre-existing castle nut.
The threading is irrelevant since you should be using the Norc castle nut. If the brake will not fit over the muzzle itself, it may be due to interference with the spot welds that held on the flash hider.

when you get it, use the norc castle nut, US castle nut might work, the Chinese thread is not precise. nice thing is if you want to use another muzzle brake, just remove the tiny allen on the muzzle and unscrew the muzzle. you now have a 5/8 thread adapter with sight. easy peasy.
This would be one of the reasons I chose this one. If I get miffed it am universal. They other thing is as a civilian I have very little use for a flash supressor... Muzzel brake would be far better.
I have a couple of the SEI muzzle brakes for ARs - same design, but scaled down for .223.
Frankly, they are not all that effective and there are better designs out there.
It is possible there are differences between performance between the .223 and .308, but I would imagine it is slight.

OP
Go back to your link. in the Q&A section. Read all of the Q's & all of the replies.
You will note, that the friendly staff at Brownelles answer your question with an affirmative "yes it will fit Norinco & Polytech"
You will have to use the OEM castle nut that came on your rifle.
I have 3 of the SEI units. I think they look mean/cool, but they really don't do all that much as Beltfed noted above.
Cheers!

I could not access that party of the site... I have been hit with malware on my PC... Thus I came here. But yes maybe I should have used my smart for to do more then look at gun #### and post pics of my dog using our pug as a pillow after his trip to the vet...
Either way panic attack averted.

don't know if I posted in this thread yet, but in Canada, I've built and shot more of these rifles than most folks and hands down, without a question, based on shooting numerous rifles in 16", 18.5" and 22" , both standard and medium profiles, and obviously in .308 , with the smith enterprise coast guard brake (and others for comparison), it IS the only brake I will spend my money on for these rifles.
personally I don't think trying to evaluate a brake on a .223 for comparison is even worth mentioning. recoil from .223 is so miniscule, I wouldn't even waste my money on putting one on there, flash hider maybe.
don't fall for the gimmicks or the comments from guys with minimal hands on experience.
it will fit the norinco rifles, just re use your castlenut or force fit an m1A one. that works too, done it many times.

I find it awesome that you're so dismissive of other people's experience without one iota knowing what that is.
As I stated SEI has scaled it down for .223. Despite your assertion otherwise, .223 does in fact have recoil, and it is not minuscule as you claim, in particular firearms. Having compared numerous designs of muzzle devices for the .223 with the corresponding .308 versions, it is my thought that the SEI brake is marginal in function. So marginal in fact, I wouldn't waste my money switching from a flash suppressor to one - regardless of rifle caliber. I'm not a pontificating, dismissive, self-professed expert however, so as always, ymmv.

well.... when it comes to muzzle brakes on the m14 family of rifles...... back in 2006 when I quietly joined this site..... I tried to be humble about it , but I started teaching m14 clinics (just like hungry does minus the range expertise) as a 'self proclaimed' expert. At least one could say that according to their perception of me at the time.
So 10 years later...... pontificating? being dismissive? well, I've been called worst things, but my "expertise" as far as it relates to this thread.... and the platform in general, has been vetted and vetted and vetted again..... you might be wise to sit back and accept that.
or not.....
in the end, I'm not a big funny happy, charismatic person like good ol barney (tactical teacher/hungry) I'm an azzhole who speaks his mind, calls a spade a spade, and doesn't suffer fools, so deal with it
I'll add that I used to be real easy going and a nice guy, looking for the good in everyone and yadda yadda yadda....... all that got me over the last decade was screwed over, ripped off, slandered, defamed and generally a permanent bad taste in my mouth hahaha. that all stopped a while back when I took a big step back from the "industry".
so if I come off as a pontificating , dismissive, know it all...... well, too bad, in my own way I'm trying to help by being clear and direct and cutting thru any misconceptions or poor advice. If you don't like it and feel a need to take it personally, there's nuthin I can do about that.
k, there's my post for today. maybe i'll have another gem tomorrow
