    As if you are the God knowing all of the internet.  Sorry, this is the bathroom wall of society, I take everything I read or see with a grain of salt.  You have to prove yourself to me just like anybody on youtube.  I don't easily recommend any forum, channel, ect.  You have to prove to me that you know enough that I'm willing to recommend you.  This forum and it's members are not the end all authority, nor am I.  

    This isn't Barfcom, if you're around long enough, that'll become apparent pretty quickly. We were here before large ARs had any kind of substantial market share, and the information that's freely given here is directly from experience and first-hand knowledge, not conjecture. Before you go making unflattering comparisons between this forum and the rest of the internet, take into account that the core group all know each other, most have met each other in person on more than one occasion, and all are part of a tight-knit family that's only partly forum based.

    You're welcome to benefit from years of things we've learned the hard way, at no cost and substantial benefit to yourself. If you feel like wasting that opportunity on arguments based on conjecture and conflicting hearsay, don't be surprised when it's not well received or even outright mocked.

    Information offered here comes directly from first-hand experience, if you want to make that out to be just more internet pablum you're in the wrong place.

    So these are all good data points, but we still haven't found any definitive info that mixing components is automatically unsafe for any reason other than headspacing variations.  

    And likewise there's no definitive data that says that mixing components is safe, so for both reasons of common sense and forum liability, I'll continue to recommend folks match their bolts to their barrel type until you're willing to foot the bill for any lawsuits against the forum.

    No sir.  I certainly want to be safe and definitely don't want to encourage anyone else to try anything that might cause harm.  

    Now please educate me as to where the problem lies assuming that HS is in spec.  If the bolt locks up properly, doesn't disengage to early, where will the danger lye?  Not arguing, just want to know what goes wrong.

    The problem lies in what can be expected to go wrong when up to 62,000 PSI (Max 308 SAAMI spec chamber pressure) is applied to various components that were NOT designed or specified to be compatible with each other. There isn't a standard here, no uniform specification. It's not a small frame AR with a Mil-Spec shared among manufacturers. There is not only no guarantee of compatibility, there is no design nor specification of compatibility. I've worked in manufacturing and machining for quite a few years now and I know full well what tolerance stacking, complacency, and various other quirks of human nature and flaws within the human attention mechanism can mean to a finished product. Combine that with the random outcomes of mixing unmatched components from varying manufacturers with varying degrees of quality control and you're begging for a disaster. This surely can't be difficult to grasp.

    I too have been on the same trail as you.  I'm probably on many watchlists now with all the searching I've done.  I've about concluded that if 1) the headspace is in spec and 2) you overcome the difference in gas tube length, then it will work.  I think it is wise to not intentionally seek to mismatch components from the two different styles, but if that is what you have in todays climate then its worth investigating.  

    I haven't found evidence that the bolt and extension lugs will damage each other, or any other damage to the rifle.   Once again it seems to be safety first and that is verified/denied by checking headspace.  

    This is my opinion for now and not intended to guaranty success or safety for others.  

    Just go for it, if you lose a few fingers you can still dictate a nice post for someone else to type so we will know what the results of your experiment were. We're all about lessons learned and data points. Be sure to include pictures. You get bonus points if any part of your gun ends up embedded in any part of your head. Be warned, I WILL laugh and/or shrug and say you knew better.

    This is your chance to be a pioneer and become a legend in your own time, don't let the naysayers get you down.

    Unfortunately, it looks like the aftermarket has only produced a captured spring buffer system for the standardized AR-15 mil spec, probably because that's where the majority of sales lie.

    It's surprising that this would be considered a logical conclusion, given that a captured spring buffer is designed to satisfy a complaint with a working system, rather than solving any actual problems of function.

    Looks like the wrench is right position for loosening with the solid part being the heel on the bolt. Just my 2 mag's

    I could very well be wrong, it wouldn't be the first time...

    I abhor using an adjustable anyways unless it's just unavoidable.

    What is the actual measurement of a 308 go gage? From top to bottom.

    If you're looking for the overall length that will differ between gauges, however the standard go gauge length to the shoulder datum for the case is 1.630" and 1.634" for the no-go.

    OK if I am elk hunting and come up on a Redhead and a Blonde fighting on the ground and they tell me I can have the winner to do with what i want, and the redhead wins I should take the looser right ? or should i just run!

    I was going to say that is easy to answer, but then I remembered that you could also resume hunting, and now it's a really difficult question again.

    The DEWS moniker was the greatest gift ever bestowed upon me, and I didn't know it at the time, when these sneaky fuckers did it. 

    I AM the Dumbass Early Warning System here...  :laffs:

    I can't even count the PMs I've gotten from newcomers asking, "WTF is DEWS?". 


    ... If you have to ask...

    Can you imagine this place had an HR dept. we'd all be spending all our time in sensitivity training... :laffs:

    Tom IS the HR manager, and easily the most sensitive and understanding person on the forum. You can't imagine how much the rest of us hate him for it....
