Value of a Flash Hider/Muzzle Break

The barrel thread on a Norinco M305 is an M15 (which is different to everything else)... and there will be a new muzzle brake, specifically for this version of the M14, available in the next few weeks from a Canadian manufacturer and which Colonel Mustard will be retailing. :)
 
Any more word on that new brake from Colonel Mustard?Thanks for the quick delivery on the parts for the Wife's sks by the way.She was pretty happy Christmas morning.:cool:

Good to hear, Scott - thanks!

I have now seen the finished item installed on an M305 - and it looks really sharp! As soon as testing is complete, they'll be hitting our site. No firm date, but soon...
 
muzzle brakes do the job that they were intended for, however they are loud and can permanently deafen you if you are standing beside a high power rifle without hearing protection. My 338 Lapua and 338/378 Weatherby is a testament to that. A muzzle brake is completely unnecessary on a M305 norinco, the activity of the gas system and bolt during firing reduces the felt recoil significantly. A 7.62X51cal or 308 even in a bolt action with no gas system does not have a heavy enough recoil to warrant a muzzle brake. Now as to a flash hider, not necessary unless you are in a firefight with the enemy during the night. A flash hider hides the flash from the shooter not the shoote. I left the flash hider, on my M305 simply because it came with one, hides the ugly threads on the end of the barrel for the castle nut and it also looks cool.

ok do not send your m14 to have the gas system unitized.
first off a proper op rod guide will take care of this. look a little more at M14.ca their op rod guide takes care of that, and also has a tensioner on it to the stock, i have the whole system from them, and if you are looking at getting right in and tuning your m14 there is no comparable parts to the ones sold by frank at m14.ca

muzzle break, i don't know what other people are saying on here as i didn't read every comment. but so its been said. do not use the factory threads.
they are too weak and not proper 1/2'x28. so you are going to need to do a cut and crown then thread your barrel. some people are putting usgi muzzle brakes this is unsafe as the norinco threads are not strictly speaking compatible. muzzle brakes will reduce felt recoil and are shooter friendly.

ps as a side note, m14.ca is putting out sometime in the near future a left side charging handle... so keep your eyes open for that
 
A .30 cal thread is usually 5/8" thread,the Norincos are a Metric 15 thread.It has nothing to do with the threads being incorrectly cut.
Ruger puts brakes on all the new RPR "enhanced" guns,so there must be some merit to it.
I've got the factory one on my .300 Blackout AR,which hardly needs a brake,but the gun is so soft shooting and stable,it feels like a toy.
And as for shooting .338Lapua with a brake and no hearing protection?You'd have to be just plain goofy to do that,or much of any kind of shooting without some type of hearing protection.
The OP just wanted to know a bit about muzzle devices for his M305.

Personally,I wish we could run a suppressor as a muzzle device.I bet the neighbors would be lots happier around here...

We've just had confirmation from Matador Arms that we will be getting the first M305 muzzle brakes hand-delivered to us tomorrow morning at the Thorncliffe Gun Show in Calgary!! Thank you Matador Arms!

If you want to check them out, look for the moustache balloons to find us.

They will be on the Colonel Mustard website on Sunday... hopefully we'll have some left after the show!

Got one! The Matador Hammerhead muzzle brake fits perfectly on my DA SOCOM18...I've been wanting something a little cooler than the reversible brake that came with the gun, and the Hammerhead is it, and the price was right too. The Hammerhead is the same overall length as the original brake but is a trifle slimmer in width...all to the good, IMO. The instructions say the Hammerhead should be attached with Loctite on both the brake and the set screw [the screw and hex key is included...no crush washer is needed], so it's not exactly an easily reversible modification FWIW. The Hammerhead has a smooth nitride finish that contrasts with the phosphated/parkerized finish of the barrel. After I shoot it a bit I'll put some comments on the Battle Rifle forum...

First off Frank at M14.ca makes some pretty good kit. I use some of his stuff, but I also didn't drink the Kool-Aid....

Unitizing the gas system is the single most beneficial thing to consistent group size and shrinking groups after a rifle has been indexed properly. It has been my experience that a guide rod is nice, but it does less to increase accuracy than a unitized gas system. In fact an improperly made (or fitted) guide rod will reduce accuracy and create rifle malfunctions.

The M14 Pattern rifle has a keyway machined into the barrel, the brake or Flash Hider slides onto the keyway and then a nut is utilized to hold the muzzle treatment of choice on to the barrel. These have been in use (in one form or another) for 50 years. How did they "all of a sudden" become weak and unreliable?

To the OP; Do yourself a favor and get either a SEI Coast Guard Brake or SAI Muzzle brake. The SEI is a bit more $$ but worth every penny.
