Another thing , do not confuse charging the action till it stops & compare it to the rifle firing . When you pull the charging handle all the way to the rear , there is a stop , may be the Buffer or the spring completely compressed all the way . I pulled the charging handle while holding pressure on the Bolt stop until it engaged & thats how I fed the round into the chamber & fired it to get my results . If you do the same test as I did & pull the charging handle all the way till it stops , it will probably hit every time , but that's not what happens when the firearm is fired . BCG stopped with the Bolt stop Charging handle pulled till it stopped, the marked line on the RE is where the Buffer sits in the RE with out the spring installed

Some people are just stupid . http://www.latimes.com/local/lanow/la-me-ln-army-reservists-weapons-20150415-story.html

Light Contact & slamming into it are two different things . That paper shows it made a very slight contact , but didn't leave an impression on it & can be seen on the opposite side of the paper . The Nail polish didn't even have a smudge on it . The bumper at the back end of the Buffer is for over travel protection , as would be in any buffer ,be it a 1911 or a 22 rifle , they all have one in some form or another . Could you imagine what would happen to your sight picture if the Buffer slammed or hit the bottom of the RE every time , vibration & more felt recoil would result also . I would imagine firing a M80 Ball 149 gr. bullet would even have less recoil & not even propel the Buffer back as far as the 168 gr. load . <dontknow> The paper I used was 0.004" thick.

Cool stuff , wish they would have identified the calibers & speeds.

I stand corrected , that Nail polish is some tough stuff , I smacked it with a very small hammer & it dented the stuff ,but its really on there . <dontknow> Acetone will make short work of it though . Just surprised me that on that nylon bumper , it flexed & took a beating , even though it was a baby Hammer .

Another thing is , the depth of the Buffer/Spring channel in the Extension , you can get varying depths & just a little difference , shorter or longer & you could have problems . This Extension is short of 7" by about a 1/16" , if it was exactly 7" the Buffer wouldn't have come close at all , well as far as hundreds of an inch is concerned . I guess we need some more research on this Manufacturers Receiver Extension . Maybe like has been said , its not installed correctly or maybe the Manufacture has a specific spring & Buffer to use , I have no experience with this product ( Too Expensive for my blood ) I used to fish a lot when I owned a Boat & ya , its always the latest & greatest , but there were only a few that really worked . <laughs>

That looked like it would leave a mark ! <thumbsup>

Yes & it will make hair grow on your palms <lmao>

Looks like they are not really cured . http://news.yahoo.com/ebola-virus-found-semen-six-months-recovery-104351981.html;_ylt=AwrC1CpbkS5VNj8Ae3nQtDMD;_ylu=X3oDMTByZnU4cmNpBGNvbG8DYmYxBHBvcwM5BHZ0aWQDBHNlYwNzcg--

Just like those who say it was the NRA fault for the 1986 deal on Machine guns, The last time I looked , the NRA doesn't have a vote in Congress or Senate.

Your not right in the head ! <lmao>

Interesting results at the range today with the test of the Buffer in an 308AR DPMS Buffing system . I didn't set up the Camera , because after looking at some of my videos , it doesn't have the high enough speed to capture or may not capture the event I need . I used a hand loaded 168 gr. Barnes LE bullet in a LC case , I'll have to look up the loading , but I can assure you its not a limp load . The Buffer did leave a mark on the white piece of paper , but I would hardly say it slammed or even hit it with any authority , because though it did leave a mark on one side of the paper ( the Buffer side ) it didn't leave a mark on the other side . Which tells me it touched it , but not hard enough to compress the paper , so I wouldn't even say it hit the bottom to the RE. Here's the Buffer side Here's the side against the bottom of the RE, notice there is no pass through mark , if it was compressed , like if I hit it slightly with a hammer , you would see it on the other side . Like how thick is a piece of paper ? I will measure it later. I also painted the back of the Buffers Nylon bummer with red nail polish & no mark on it . It would have cracked or chipped it hit even slightly . If you don't believe me , smack a woman's nail with a hammer ,thats polished & see if it chips or cracks . Here's a photo of the paper in the bottom of the RE & at first I thought it didn't leave any kind of mark . With the slight & I mean slight marking on the piece of paper , you have to take into account that this is a very used Buffer spring , the added thickness of the piece of paper & the nail polish , I don't think It would have even left a mark at all . There is only 1/4" to play with between the Bolt locked back & the Buffer touching the bottom of the RE., so there's not much to play with . This system is not unlike a lot of gas operated systems out there in Rifles , its a fine balance between weight ( mass ) & spring compression to keep them operating correctly & not punishing other components . In this case the RE, its threaded attaching point. If the Buffer slammed or hit the bottom with any kind of authority , you would get bolt Bounce & could cause FTF & FTE issues . Note that this is all DPMS Components in 308 Carbine configuration & if you are using anything else , your results , I'm sure will very .That goes for you guy's using AR 10 components in a DPMS format . Sure it works , hell I can pretty much get anything to work , but work correctly , the way it was designed , is another thing .

Have anyone here had problems ejecting cases , that can be traced to the Ejector , that you would need two Ejectors ? I think they are over kill or covering up for something else in the design of this rifle system or could be just copying another well known manufacturers design.

Thing is , this ATF form , the" I'm not the original buyer "was checked , so they say . Even in my day , before the back ground checks , I'm not I would have sold the firearm to this person . I'm not even sure that question was on the ATF form back then . That may make or break this case . I can't help but feel sorrow for the LEO's shot & what they have been through .

Well that subject went to SEX , very quickly . I was hoping someone that had some info on the case or its circumstances , but Nooooooooo, it was derailed because of SEX ! <lmao>

This deserves watching for an outcome . http://news.yahoo.com/milwaukee-gun-store-sued-for-supplying-guns-to-criminals-165403308.html

Here's a study that's worth reading , even the reporter that wrote about it ,has a hard time believing it . I like the part about caring guns outside the home . Does that include Hunting <laughs> http://www.huffingtonpost.com/mike-weisser/gun-owners-impulsive-angry-behavior_b_7054146.html?ncid=txtlnkusaolp00000592

Fired brass was never meant to be reloaded or should I say , Firearms manufacturers really don't care if their design screws up the brass for reloders , as long as it is ejected & the next round is chambered & ready for firing . I know that doesn't help ,but just the way it is . I have a fine flat file for brass that has slight burr's on the base & a three sided for the extractor grove , it doesn't take much to dress them up . As long as you don't go crazy on the filing , should be good to go . I believe the 16" has a Carbine gas system & the Adj. gas block may help <dontknow>

If its touching the bottom of the RE , its not much or very hard . I wouldn't use the term slam . The Tubb's flat wire spring does not let the Buffer hit the bottom of the RE , it definitely stops the buffer by spring coil bind or what ever you want to call it . Everyone has to understand that by the time the Buffer gets even close to that far back in the RE , it has slowed down a great deal , because of the Buffer Spring & loss of momentum Just because we can compress the spring enough to have the end of the Buffer hit the bottom of the RE or a clear tube , doesn't mean it hits the bottom when fired . As far as the Camera , my Contour video camera & my software in this Macbook can be slowed to frame by frame , should work , but I will put a white piece of paper at the bottom , just to be sure <thumbsup> I'm going to the range today , if it doesn't piss all day like yesterday .

Contact them & send them the photo of your fired brass . I don't see a problem with reloading that brass . Primers are not pierced , so why worry <dontknow> Looks to me to be to large of a Firing Pin hole in Bolt .There was another here that showed the same Primer condition , never heard back , so maybe with a higher round count , this symptom may go away ( hopeful ) How does the sides of the brass look like , could be a rough chamber, tight chamber . If you have followed DPMS rifles , they have had a history of rough/tight chambers.

I believe he already did it . <laughs>

Why ? Oh wait, I know , its the, my bike is faster than yours , naw naw na naw naw . <laughs> That's all the Rice Grinder/Crotch Rocket lover's care about, RPM's or top end . Its the only thing they have going for them , its surely not resale value . <dontknow> <lmao>

Check this info out , may be some leads to parts. http://rifleman.org.uk/BSA_Spares.htm

I can see why some Manufacturers want to make components to their spec's , it makes sense in a way . Most have statements professing their Parts may not play well with others & some still don't . This is the way we have been finding the combinations of components from different manufactures that work with the three main or more , 308 AR platform. Isn't there a Pined Thread here some where ,that shows what works with what . As far as the end of the Buffer hitting the Bottom of the Receiver Extension , this particular Extension was to test hand loads , was used with my Criterion ,16" HB & had a bunch of over pressure ammo through it for testing . The bottom of the RE was inspected before I did Surgery & the was undisturbed oil on the bottom , where the Spring seats had none , but I could tell the Buffer if it hit at any time would have left some kind of mark , from all the ammo shot through it . I can tell you , I never cleaned the RE out , I cleaned the Buffer & spring , then re-oiled , but never cleaned the RE out . I like the idea of the paper , but don't think you even need to mark the Buffer , its going to leave a mark on the paper when or if it hits it , it will show on the paper. I was going to try to paint the side of the buffer Red & use this opened up Receiver Extension & film it , just to see if I can see it movement in slow motion . I just get too curious when I'm not sure of something , I have the need to know ! <laughs>

True , but I can't see any advantage to being one of the first to own one . They won't see many miles on them to break anything , a show off bike, like a safe Queen . <laughs>
