goldkey, I have a update on your bolt, from your previous tread,


http://www.gunsnet.net/forums/showthread.php?threadid=59361

after talking to my buddy...who is still in the Army, he says it sounds like you may have a old M2 practice training bolt, that was used to fire the M862 plastic practice cartridge for shooting in indoor ranges. the active army got rid of them when they went to the M261 .22 conversion bolt, thereby using off the shelf .22 ammo, which is cheaper then them making these plastic practice cartridge.
he indicated that it is not a good idea to fire regular rounds with it, as it may cause the bolt to have a catastrophic failure, that may cause you bodily harm, because of the chamber pressure is very high, then the loads in the plastic training rounds, and the bolt is of weak metal…also the head spacing for the bolt although not really needed for the plastic ammo, bcause of the low pressure…..will not be the proper for regular ammo.

I suggest you replace it with a real bolt, before something happens you don't need or want, on your next shooting session. Just make sure you have the real bolt head spaced to your rifle…..don't buy one and put it in, and figure it will be good to go.

Hey, I appreaciate your help about this. I will take your advice. I wish I knew someone I could have look at it close by. The bolt is a metal of some sort, what kind I can not tell. It just feels super light to me, kinda like when you pick up one of those light wieght revolvers for the 1st time if you know what I mean. I don't even know who will headspace a gun for me around here. I have one place in mind, but I'm not sure they do it.

you can just buy a field gauge.....this will tell you if the weapon is safe to fire. the military field gauge, doesn't require you to take the ejector out....just put the gauge in the chamber, and then MANUALY bring the bolt group up to it, and apply thumb pressure, don't use the bolt release to slam into it the gauge...the bolt should not go into battery. you could buy the go, no go gauges.....but it isn't really neccesary. the object is to get a bolt that will be safe to fire from your weapon. BROWNELLS has the gauges.

Has anyone thought it could be a Titanium alloy? Titanium is lighter and stronger than steel. If you have ever felt a watch with a titanium case or band, it has a plasticy feel to it. Titanuim is usually grey in color compared to steel/aluminium. If it is titanium, that thing will last FOREVER! just my .02 ;)

you described the look and feel of the metal exactly, it must be titanium. Thanks for your input!
