Hey Guys;

Post your links to extended bolt releases for the M14. I'm looking for the "most affordable version", for fear that my #### might fall off!!! Here is one that Hungry sent me, a mile high $58.33 USD, plus shipping!!! UGH!!!

http://www.brownells.com/aspx/NS/store/ProductDetail.aspx?p=22187&title=M14/M1A BOLT STOP

Now, what would make life SWEET, is if one of you pm'd me with a Rooster33 (R33) extended bolt release... (I have NON-corrosive NATO headstamped 7.62/308 I am willing to "discuss"...)

Cheers
Jay

Do you think there is such a thing for M14 parts?;)
Anything coming across the border is EXPENSIVE! Too bad WE don't figure that about BEFORE WE purchased our M14's.:D

As H20 man said, the SEI is quite good, but I dunno about cheap to order. I ordered mine directly from SEI, great people to deal with. Also you might want to check about FabSports, or Wolverine Supplies as there carry a good selection of M14 parts including Sadlak and SEI to name a few...

Is rooster33 still making M14 parts??

+1 for the SEI bolt stop, yeah its 58$ but well worth it if you want an extended bolt stop.

Will Brownells ship the bolt release to Canada without an import/export permit, or is it classified as a nasty gun part, therefore; requiring the paperwork?

0 paperwork. Mine is on the way with via USPS Air from Brownless as I write this.

What rockwell hardness do they need to be?

Why not just buy some good quality steel and cut a butt load of them out on the water jet? smooth the edges the old fashioned way.
 
I put the rooster33 one ahead of the SEI one. I like the feel bump top and bottom for force open, and slam closed.

With any of these extended releases, remember that if you lean your rifle against something, or put it down on the non oprod side, odds are good that the bolt will close. Made that mistake once.
 
From a posted drawing of the USGI M14 bolt posted on www.milsurp.com:

"Heat treatment recommended process normalize before machining (oil quenching followed by tempering at not less than 450 deg F may be used in lieu of air cooling). Carburize at 1550 deg F to 1600 deg F to specified case depth. Without reheating, quench in oil or neutral salt bath from 1500 deg F to 1600 deg F; if reheated, quench form 1550 deg F to 1600 deg F temper to hardness specified.
Mandatory requirements:
a. normalize before machining.
b. carburize to case depth .012 to .018
c. temper one hour minimum at 350 deg F to 450 deg F
d. core, Rockwell hardness C33 to C42. Surface Rockwell hardness D66-71 or (Referee method) 30N-74 minimum on a properly prepared surface.
e. microstructure of core shall not contain G E F (sic. whatever that means) more than 10% free ferrite after heat treatment per AMS 2315.
f. the use of a straight cyanide bath or carbo-nitriding process shall not be permitted
g. when gas carburizing is used the carbon content shall not exceed 0.84% at surface of component per AMS 2762."

All this tells me that a USGI bolt has a core and a surface hardening. A bolt release ought to be somewhat softer than the bolt.
