So I recently bought a springfield M1A. however I want to install a muzzle brake, and would rather have the barrel cut crowned and threaded 5/8 x 24 than use an adaptor due to the fact that the threads on the rifle weren't really designed for said purpose. does anybody know where in Alberta i could get said work done? I know i could ship the rifle away (Dlask, and other shops) But id rather take it and drop it off myself. thanks guys
M1A Barrel Threading

You can't properly thread an M14 barrel to 5/8 x24 , the diameter is insufficient.
I would question any machinist who says or does otherwise.
The safe options are an adaptor or have it cut back to where it is sufficient diameter for 1/2x28 threads.

There are also several options out there that mate to the M1A that are pretty effective muzzle brakes......
For instance http://www.armtac.com/product/sei-2001/
Or an adapter as 45ACP suggested. http://www.armtac.com/product/sei-2002/
Both are out of stock, but a phone call would get you an eta. Or there is always brownelles, just gotta keep it under $100 or there is paperwork, over $500 and the paperwork involves a rectal exam from the fine folks at State.......
Cheers!

Thread adapters are considered "muzzle devices" and Brownells won't export them. At least not the gemtech ones
Gem tech makes a nice adapter but I can't find one for sale here in the great white north. The smith enterprises ones are available, one of the local shops has some of their parts in stock. But I'd rather not have an adapter with a front sight base.

Smith enterprise makes a direct connect good iron brake that will thread right to your barrel's existing thread, nothing else required. Widely considered the best performing brake for these rifles bar none. In my experience, with almost every commercially availlable M14/M1A muzzle device, as there's very few I haven't installed and tried... The coast guard or good iron brake from SEI is the way to go.
I just recently ran into the same problem and the Gemtech Adapter solved the issue. It added some extra length onto the barrel though, but that was expected. Grizzly Gunworks can make thread adapters for any internal/external threading...maybe give them a try.
Does the "SEI Good Iron M14DC (Direct Connect) Compensator" thread onto a 18.5" M305 without any mod issues, just remove original and screw on with some red LT and good to go? I don't plan on using iron sights so this would be a cleaner look. I could always use the "SEI GLFS-D-18.5 Dovetail for 18.5"" if iron sights are desired.
TIA
the smith brakes are pretty good, i don't deny that for a second, smith ent. has done great things for M14 lovers. i have a good iron brake on one of my other rifles (this is my third M305, and second M1A) i was seriously eyeballing one of these to put on the springfield in the sage stock:

although for anybody looking they do have one of these brakes threaded for the chinese rifles.
im scared that with the amount of gas this thing redirects that the difference in threads could lead to failure.

Okay. I've had issues like this in the past where some loctite was all I needed to resolve the problem but is safe for the M305? Anyone installed one of these on a M305?
Otherwise I can use the one that requires a castle nut.
That sucks but Canada does seem to get far fewer options. At least we can still get the Norinco's for under $600 on sale.
Thanks for the quick reply.

I have used and installed the direct connect vortex flash hiders to many an M305 barrel with satisfactory results. I would imagine the DC goodiron would be the same. Loctite would be a good idea tho.
If yer set on a gas lock front sight, JohnnyVolume had some listed in EE that are made for the M305 gas lock thread. I've also bought and installed several of these and results were excellent.
In case anyone else wants a peek:
http://www.hical.ca/witt-m14-305-mre-muzzle-rise-eliminator-black/
"These are threaded Metric M15 -.75RH. Available in Black Only"
Thanks for the additional option. I like the cleaner look of the brake without the sight since I need a scope anyway.
The dlask arms adjustable gas lock is a great option. gives you a gas lock front sight and they make them in both metric (M-305) and english (M1A, and aftermarket barrels). it eliminates the need to shim the gas system and also gives a dovetail.
Thanks. I'm not planning on it as I'm ordering a CASM but if the scope ever fails or I bash it on a trip it might be a good backup idea since the CASM has a peek hole.
Seems I need access to the EE group. I'll have to check that out later.
depending on the stock you use the back up peep hole may not be very useful, due to the height it makes the backup peep hole hard to use. the cheeck risers on both the archangel and especially the sage chassis the peephole becomes virtually unusable.
the archangel is a nice stock. thats my first m305 build in the pic. my first springfield is in an archangel. the nice thing about the archangel is thec riser adjust is much simpler. just crank it down and irons are usable. the sage requires a bit more effort. my newest springfield will go into a sage chassis, muzzle brake and barrel are the only parts im still waiting on
