Hope it all works out OK .Good luck .

I would think all .50 cal. die sets are made to the same spec's ,but I could be wrong . There could be other issues , what reloading press is he using ? What brand shell holder ? There may be conflicting issues using one brand with another brand as far as mixing die sets & shell holders.

I picked up the magazine & read the article & I don't know what AR 308's they are used to shooting , but both of mine will eat any ammo I put in them . I do agree these type rifles can be picky , if ,the improper components are used , but that will be the case with any semi auto fed rifle . I will say that I have a CMMG lowered build that just will not feed reliably with Magpul P-Mags , but works with steel mags., so I guess that would put it in the picky category they speak of, I guess . The rifle still will shoot any thing I have put through it with the steel mag.'s , so I don't know where they refer to these AR 308's as finicky . P-Mags were not made or available when the CMMG lower was produced , so ya can't blame them or Magpul . Just one of those non mil spec production items that all ,but maybe Armilite , will have to put up with. (That is unless you use non Amilite components ) It was interesting on the subject how Black Hills went through the process of making a more efficient round for the Military. I sure would think the AR 10 he reloaded for would have got better groups then he posted .

A very good deal , indeed & its well made & finished .

Interesting , but for what purpose ? Unless you just want to change different length barrels or different calibers that use the same bolt face & or magazine . IMO , it would be more logical to just have or carrie a complete upper assembly , ready to go .

That tool also does AR 15's & I removed them for many years with my hands & a pin punch. That tool makes it so easy to remove /install , you will want to disassemble & clean & inspect more often.

I see if I can find the org. blade & peep also & take some photo's .

Maybe the scope was loose all along & it had nothing to do with the bullets ?

Brownells has a nice tool for removing the ejector . http://www.brownells.com/gunsmith-tools-supplies/rifle-tools/bolt-tools/ejector-tools/ejector-removal-tool-prod23114.aspx?avs|Make_3=AR-15/M4&avs|Manufacturer_1=BROWNELLS The photo's in your post #6 ,looks like components are on the dry side ,as far as lubricant . I'm curious about the wear mark on the out side face of the bolt carrier .

Never thought of putting a brake on my M1 , I'm sure you are going to give a shooting report to us <thumbsup> . I have Match front blade & rear peep on mine , big difference over std..

Well , then you can move where ever you want . <dontknow>

Nice Brake , who's the manufacture r?

Number your magazines for reference in testing. In some cases you can use masking tape with the numbers . I use red nail polish , but don't tell my wife .

I just don't get it , I thought they were a good co..

Does any one know of some one who used his components to build a rifle ?

<munch>

What part about "not infringed " don't they understand ? If I said you can buy or own any car as long as it was a GM built auto , how would that go over ? I think there's more to this than just firearms , maybe there's another angle on our basic consumer rights or some thing to go on . You should talk your in-laws into retiring to here in Florida, we are still a free state , like most of the south.

Here is a list for you to start & others can add if they want. As said , make sure you have the correct components , buffer ,spring , receiver extension (buffer tube ) Start out with the std. action drill , one round (does the BCG travel far enough for the now empty magazine to hold back the Bolt Carrier Group) two rounds , does the BCG hold back, three & so forth , till you get to the twentieth round in the mag.,you get the idea . You can install fully loaded mags & fire till you get a malfunction & take note on when & what type. You can use the same mag. & if you use the same brand of mag's , number them . I don't care what manufacturer's mag you use , any could cause a problem , they are mass produced. Does the rifle malfunction at any time in the drill , stop & note the type of malfunction . Inspect the fire control group (trigger,hammer , disconnector )all working to spec's ? Any unusual wear on any component ? Make sure the gas block is correctly installed , even if you have to take it to some one to make sure. This is only a partial list & there is much more . Don't let this get the best of you , you have to be some what of a detective on some rifles to get them to fully function to spec's , The answer is there & probably some thing simple . As far as a little grease , I've been repairing & building ,both select fire & semi auto AR's for over thirty years & never had a problem with using it. The key is , as with any thing else , is do not over do it .

Go for it & see how they group .

Should only need to run them dripping wet during initial break in, as said & that depends on how long every thing takes to wear in . After break in , shouldn't need any more than normal lubrication , per manual . Check to see if there is a mark on the disconnect from the hammer hitting it & use a different manufacturers magazine, just to see how it functions with the rifle. Changed the gas block ? Change it because of the FTF or did the FTF start after ?

That's a good deal . I have a Vortex on the Wife's Carbine & its sweet.

Going that many rd's before a FTF , ummm? Try a different manufactures magazine .

Could be bolt bounce , from too much gas or short stroking , for that matter . That jam ( FTF ) sounds just like my CMMG when I use PMags . Almost bends the case in half some times,other times just some deep gouges. Could also be binding in the action & don't leave out the fire control group . Weak buffer spring or its binding .

Still would be nice to see some Chronograph results on your reloads , might answer some questions. There are a lot of good powders for the 308 cartridge , I would try others , you can get different results & may find a sweet load .

I have a CMMG lowered 308 build , that will have FTF with P-mags & P-mags only. I believe most FTF are mag related. When building a AR , using different manufactures for upper & lower receivers , tolerance differences between them can cause many problems , including FTF.
