6132expert Posted February 9, 2011 Author Report Share Posted February 9, 2011 Hy guys one thing.In order for me to shoot the Nato 7.62 in my Rifle do I need a barrel that is chambered for the 7.62 or upper or is a combination of both?I am thinking the barrel needs to be the part to take the added pressure. Some insight to this would be great. Quote Link to comment Share on other sites More sharing options...
Madhouse Posted February 9, 2011 Report Share Posted February 9, 2011 I used to think the 7.62 NATO / .308 Win was the same situation as the 5.56 NATO / .223 Rem, where the NATO was the higher pressure round. But, thanks to this forum, i was corrected. The .308 Win has the higher pressure, so be sure to get a barrel rated as such.Unless I still have it backwards...??? <munch> Quote Link to comment Share on other sites More sharing options...
6132expert Posted February 9, 2011 Author Report Share Posted February 9, 2011 OK thanks for that info.I hope you don't have it backwards Quote Link to comment Share on other sites More sharing options...
survivalshop Posted February 9, 2011 Report Share Posted February 9, 2011 With modern barrel materials & manufacturing , it makes no difference of what the difference in chamber pressures are . The difference is in the chambers , with the 7.62x51 having a longer lead to the rifling . The 308 chamber is considered by some as a match chamber .You can shoot one or the other in ether chamber with modern rifles or barrels ,with out problems.One may shoot a particular round of ammunition better than the other ,but I see no difference, I will shoot 308 in a 7.62 chamber or 7.62 in a 308 chamber.We are talking about 308 AR's, The match ammo most are shooting , do you think is 7.62 or 308 . I think most of your AR 308 barrels are chambered in 308 any way ,unless you specifically ask for the 7.62 chamber dimensions.Now when you get into .223/5.56 things are a little different .

6132expert Posted February 9, 2011 Author Report Share Posted February 9, 2011 Well I kew it was different with the .223 and 5.56. My RR LAR-15 is Chambered for 5.56/.223 So I know I can shoot eather one in it. I assumed the .308 would also be the same, but thnaks to you guy I now know different. That is good that it will not matter. Quote Link to comment Share on other sites More sharing options...
6132expert Posted February 10, 2011 Author Report Share Posted February 10, 2011 Got my GA trigger and lower parts kit put in today took me all of about 45 mins.

6132expert Posted February 11, 2011 Author Report Share Posted February 11, 2011 Man you are great.Thanks for leading me that way. I think that is the one, and they make from what I have seen a good product at a very competitive price. I have to get a Roll Pin Punch set some Drifts and a nice hammer with changeable heads. I am sure I will find more to get.After I got into the parts kit and the trigger , I found all I need for the lower was a Rubber Hammer, a Flathead Screwdrive, and a Center Punch. I really thought it was going to be much harder then it was, and now I am sure I can assemble a lower in 15-20 minutes. <thumbsup> Quote Link to comment Share on other sites More sharing options...

6132expert Posted February 11, 2011 Author Report Share Posted February 11, 2011 Dang , I did nt see that!!!Now a Tube, BUffer and spring for and LR-308 AP4 will work, Im I right on that? Quote Link to comment Share on other sites More sharing options...
TacBlade Posted February 11, 2011 Report Share Posted February 11, 2011 Go to Brownels. They have all that you need. You can use the carbine buffer on any 308 AR, you just need the 308 specific spring and buffer for either the carbine or rifle length buffer tube.

imschur Posted February 11, 2011 Report Share Posted February 11, 2011 If your looking for a budget way to get the ball rolling check this outBTW regarding ordering from DPMS directly. It's been a mostly bad experience for me. You have no way of knowing if youll get your order in two days, two months or two years. Quote Link to comment Share on other sites More sharing options...

Also milspec & commercial receiver extensions have different out side tube dimensions. Quote Link to comment Share on other sites More sharing options...

Also milspec & commercial receiver extensions have different out side tube dimensions.Its to my understanding that the tubes themselves are all the same size ( Diameter ) the only difference in the two are the Mil-specs threaded portion ( the threads are raised slightly higher then a Commercial Buffer tube.imschur that is a good deal for sure , and I may consider it. Like I said, the first one will be temporary until I decide what I really want on it. So that may be the best way to go, and I can always use it on a 6.8 build <thumbsup>.

6132expert Posted February 11, 2011 Author Report Share Posted February 11, 2011 Uys do the RR quad rails fit the DPMS, I really like there Half Quad and I do like RR all around. Quote Link to comment Share on other sites More sharing options...
imschur Posted February 11, 2011 Report Share Posted February 11, 2011 No the tubes are a different diameter. Identification is easy. The mil spec tube outside diameter measures 1.140" and the commercial tube outside diameter measures 1.170"Its to my understanding that the tubes themselves are all the same size ( Diameter ) the only difference in the two are the Mil-specs threaded portion ( the threads are raised slightly higher then a Commercial Buffer tube.imschur that is a good deal for sure , and I may consider it.

6132expert Posted February 12, 2011 Author Report Share Posted February 12, 2011 I would stick to a 308 carbine buffer & spring,with a collapsible receiver extension or a 308 rifle buffer & spring with rifle receiver extention. Also milspec & commercial receiver extensions have different out side tube dimensions.OK so I went ahead and bought the Magpul ACS stock, but I am having trouble finding the mil spec collapsible extension tube, car buffer and spring at a decent price.Who can point me in that direction?? I found he Tube and spring , but every carb buffer seems to be out of stock. Should I get the hydro carb buffer?Ok well I just got the parts ordered, but I over paid 41 bucks. PK has the best deal on Complete Stock kits commercial and mil spec. Quote Link to comment Share on other sites More sharing options...
