Nice looking rifle . 20" or 18"or 16" , if you have a rifle length gas system , it will stick out from under your 12" hand guard . Not a big deal , I like them uncovered , keeps them cooler & you don't have to remove the Hand Guard to service them & if you have an adj. Gas Block , it makes easy adj..

I just can't get past the use of your middle finger to pull the trigger. Maybe a in-between sight set , not so much one way or the other . I really beginning to like the Fire sight types . I use a Fire Sight front sight on my Hunting Ruger BlackHawk , man is it nice to draw up on something with that glow sight out in front .

You may have been altering or breaking your concentration with the miss fires . The trigger may have been having varying disengagement pressures ( trigger pull #'s ) & that also may have had an effect on your grouping . Light Hammer strikes causing less than normal accuracy , well, if the primer ignites , its pretty much out of your hands , so I'm not sure how it could or would matter . <dontknow> A good consistent trigger pull , will help anyone be a better shooter .

Use a 20 MOA mount & it should have no problems .

I was referring to Blue 109 , but it can apply to you also . I see where your mind is . <lmao> <thumbsup>

Interesting , I still would like to see some photo's or it didn't happen <laughs>

Ya , you should know better <laughs>

I've used nothing but , RP 300BLK or LC MilSpec Brass & never had a problem . Good to know about the different neck thickness , there's a tool to take care of that, if you want to spend the extra time to turn the necks. It was already mentioned , but some times even a slight crimp , can bulge the shoulder on a 5.56 case . Best way to tell is , if you have a Dial Caliper or a Micrometer , measure at end shoulder , before it slops into the neck ,before seating the bullet , then after you Crimp it . You can take the same Measurement after seating the Bullet if you think seating the bullet may be setting the shoulder back & it doesn't take much , to keep the cartridge from chambering. You can also measure the Case neck Diameter before & after seating the Bullet , to see how much it changes & take a measurement of a know good chambering Cartridge to see if they is a difference . What fun <thumbsup>

Yes , but the math , as far as the gap ,doesn't seem to work out or I'm missing something.

I learned on a dirt bike when I was young , dirt is very forgiving & no cage's trying to run you over , just have to watch out for tree's . The courses are OK for the very beginners. My first street bike was a Triumph Daytona 500 & its plenty for a beginner , so 500-600 CC is a decent choice . I don't ride with a Helmet most of the time , but I from the old school where I believe they can do as much harm as good . It is good to wear one & I have have been doing so more often now a days . Once you see if you have the bug to keep riding , go up to something more or less more comfortable. I say that because a bagger is for more comfortable then the crotch rockets & I don't care what they say . I have been riding on the street for over forty three years & have bounced off my share of Cage's , not to mention all the road rash . My current go to bike is a 2003 Ultra Classic , Cruse control , Stereo , the works , its my Cadillac .

I have a Nikon Monarch ( 2.5x10x42 ) w/ DNZ mount ,on my 45/70 , NEF handy rifle & its holding up so far .

I don't at this time have any Barrels not attached to something , which is odd around here , so I can't help you out . Photo's of your hand guard set up, still would be nice . The stuff we have seen here , wouldn't surprise me one bit if the flange's were not the same .

He doesn't feel pain any more , but his Spleen sitting on the coffee table is starting to smell .

His mind is elsewhere , he's got 23 reasons to be off planet . <laughs>

I had a recall a week after I bought my M&P Shield , a trigger safety issue & a friend of mine had a M&P trigger problem & had to send his back . Mass production & they have stepped up production over since the " Queen " came to power .

Did they supply the magnifying glass to read it all ? <lmao>

Looks like some shenanigans going on in Iowa . http://finance.yahoo.com/news/iowa-agency-returns-800-handguns-183857912.html

Barrel length probably has a lot to do with it , shorter barrels will enhance Bullet stability problems.

Not a normal problem , should be checked at the Manufacturer when Barrel extension installed . Not an easy fix , but can be done with the right tools & know how .

The above is correct , no two Barrel/Chambers will react the same to reloading . Its why I can wring so much better accuracy out of just about any rifle when compared to Factory ammo .

What rifle ? These are Subsonic , so stabilization , I would not think would be an issue , but too many factors involved to make a determination with out more info . You may have to do more than just adj. your loads to get them to function semi auto , hard to tell with out knowing the platform your using & the components its made up with . Primers , well that would be determined by the powder used & charge weight . You can use Magnum Primers if low volume loading powder & std Primers for a more case filling powder loading . There may be quite a bit of R&D to make the rifle function reliably with the wide range of 308 sub or super sonic loads .

How about some photo's . The Barrel nut flange on the Barrel Extension could be thicker , if that is what you are referring to , that's keeping the hand guard away from the Upper Receiver . I think most have a slight gap , how much from Hand Guard Manufacturer to another , is up to them . Also make sure the flange is seated all the way against the Upper receiver & the adaptor or Barrel nut is seated also . We had one here not too long ago that had the same problem & the flange was not seating all the way up to the Upper receiver & is what caused his issue .

Send it back for a new one , no exceptions ! Or reimbursement . Just my opinion <dontknow>

What the Mag. or a PPK ? Wee seem to have a few Mag's & no Pistols <dontknow> <laughs>

I should have known better <laughs>
