Man on a mission!! <thumbsup>

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.

Madhouse · 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>

6132expert · February 9, 2011

OK thanks for that info.

I hope you don't have it backwards

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 · 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.

Got my GA trigger and lower parts kit put in today took me all of about 45 mins. Not to bad for my first build <thumbsup>.

I do have to give thanks to imschur for the Sticky Thread on the Lower Build.

Where is the best place to grap up a Trigger Pull Gauge??

6132expert · 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>

Well you cant beat Brownells for the proper tools. I did a generic rifle tool search here.

6132expert · February 11, 2011

I much as I want to go with the PRS stock I think it is a little pricey and it may be something I add later.

With that said I am going to get the ACS and I need to know if this kit will work as a great kit for the ACS

No it wont, wrong buffer and spring,

even states the fact on the page NOT FOR LR308 RIFLES

6132expert · 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?

TacBlade · 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 · February 11, 2011

If your looking for a budget way to get the ball rolling check this out

BTW 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.

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.

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 · 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.

imschur · 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"

OK, mayb I misread or misunderstood what I was reading. Thanks for the info, I do like this site!! <thumbsup>

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.

Your doing it wrong. The trick is to have multiple projects going with tons of stuff either on order or back order. That way you forget what you have coming and its like xmas every few days.
