It's the Whidden unit. <thumbsup>

fngmike, The timing issues are set by the gas port. First the port is drilled in the barrel and then everything [thread form and shoulder] is set off the port location. The same held true for FAL variants if port location was desired to be in the groove as opposed to land/groove overlap or on the land. Personally, I've never experienced anything detrimental [accuracy] or seen an actual benefit from having the port in a given place. What was paramount was the absence of a burr at the break-out point, where the tool came through to the interior of the barrel. As to the thread pitch commonality between manufacturers: Good luck on getting two manufacturers to actually talk to each other and set the major, minor, etc. tolerances to a common tolerance and stick to the agreement. <thumbsup>

:o ... <laughs> As usual, I late to the dinner party. :-[ Today, I spoke to a fellow industry insider and he made me aware of something I was completely ignorant to with regards to ALL of the 308 AR bolts. The lug opposite of the extractor does not serve a purpose other than aesthetics. This, as well as the cam pin being troublesome due to the increased load from the 308 cartridge was interesting to me. Just thought I'd share with the rest of the class. <thumbsup>

http://www.tacticalmachining.com/ar-15-products.php Interesting that they're offering jigs and fixtures for the "do-it-yourself (er)". ;)

For all those gents who would prefer not dragging a sandbag to the range (like myself), this is a welcomed option. http://www.whiddengunworks.net/thestinger.html <thumbsup>

Welcome fellow noob. <thumbsup>

Nah, nothing to spy on and nobody to spy for. :) Although the platforms may be a bit different, the same principles apply. <thumbsup> Oh, and I do own a mouse-gun. ;D

<thumbsup> ;D Howdy, Buddy! ;)

Thanks for the warm welcome gents. I'm a retired ME from the industry. If you've ever fired a FAL type rifle, chances are pretty good something in or on it was of my doing. Cheers!

<laughs> That was a literal blast! After 14 levels, and 415637 points, my right index finger seized up. I gotta go eat a banana now. <lmao>

Just a quick hello to all the members. Maybe I can contribute to the forum in some way. I have a solid background in the weapons industry and look forward to [hopefully] sharing information with the members. Cheers!
