BIGBREW 308 BUILD

[BIGBREW]

Couple things. Thanks DWILSONMFG.COM  for getting this bolt here quick. Just need a barrel at this point. Bought the carrier months ago. 

 

Never installed a gas block after the hand guard before. I'm going to use a slim 16.5 on a 20" rifle length .936. Hand guard won't turn on the threads with block on. Any advise to installing this way?

 

I'm hoping it goes in this easy

Yeah, take the rail off.  Might seem like more work, but it's gonna be ALOT easier in the long run.

No way the rail is going to turn around the block. Not enough clearance. 

 

Can't be impossible. Anyone got any tricks to making sure the gas hole lines up at the top of the barrel? 

 

I'm sure I can slide the block on the barrel and mark where the set screws should be. Install the guard and aim for those marks when I slide the block on.

Dimple the barrel so it has to line up, SLR sells jigs pretty cheap;

Once you have a jig you can loan it out to us

[BIGBREW]

That's what I figured. Dimple the barrel, barrel will be stainless so if it already has a simple mark it with a bright marker then just line the gas block up.

Picking up some final odds and ends, need scope mounts and paint. This is what was in the mail today. Nothing special.

I have those same pins. They are nice 

[BIGBREW]

Getting down to the last of small parts. Still waiting on a barrel. Paint should be here Friday.  I'm a little surprised it isn't getting here faster with $15 for shipping but oh well. 

Still need a block for the upper and haven't made a decision yet, really with there was a clam (taking suggestions). 

Maybe start assembly in a couple weeks. These came today. They may get painted too.

Big  so even the troy micro .936 wont clear the inside of the rail?     https://bloodandbrass.com/products/troy-936-gas-block?variant=36337673351

or one of these     http://www.brownells.com/rifle-parts/gas-system-parts/gas-blocks/micro-936-gas-block-prod54725.aspx

You stated you don't have the barrel in yet....is it on its way...if not why do you want the .936 ?   Is a .750 not enough for you?   just wondering...lol          Wash

[BIGBREW]

Going with this barrel once they have some in stock. Requires .936 block.

Big   So is there no hope of me talking you out of that barrel? Is it a must have do or die kinda thing? or is there some room for discussing?     Wash

  I would like to see more of the way this HG attaches & how long is it ? If its only 12" or so , the Gas Block can be installed afterwards , because the HG will not cover the Gas Block .

My 20" HB ( Kreiger/Criterion Match BBL. with 0.936" GB ) has a early Fulton Armory ( I think made by JP ) on it & it is a rather large diameter , but I can take the GB off any time ,because it is outside the HG .I believe the GB has to be removed to take the HG off . Its been on there for so long , I forget .

Never seen a screw on HG that would not clear a Micro Gas Block , but ya never know , all kinds out there any more .

My dad and I are building this together. He was buying the barrel so I was trying to find one at a reasonable price. He's retired and has a fixed income. I'm not that worried about getting the gas block on. My handguard is 16.5"

Big....what are the NY laws regarding your building an ar308?         Wash

[BIGBREW]

Fixed stock, no pistol grip nothing with holes in it at the end on the barrel. Probably parallel with CA laws.

[JJ109]

so the stock has to be like this?    https://www.dark-storm.com/parts/stocks-buffer/nys-compliant-stocks/thordsen-frs15-featureless-stock-with-standard-buffer-tube-cover-blk/

or somewhat like it?      or this fde one?   http://thousandislandsarmory.com/frs-15-standard-stock-kit-fde/

but I see no restrictions on journal size ( ie  .936 )   no threads for muzzle device okay I see that

whats going to happen with the brute weight of a bull barrel and 20 inches hanging out there...and you having a  retarded no pistol grip stock is that the rifle is going to be so front heavy/unbalanced ...it will make for nothing more than a bi pod  paper puncher and prolly a not very good one at that....  think light shorter barrel is all im saying
