OK, so I have been thinking more and more about putting together a 223 AR for distance shooting.

I have some parts, and some ideas and a list.

I want a 20 inch barrel, so that eliminated Seekins.

I am really liking the FDE color, so i have some hoops to go through here.

First.  Available parts.  I have a PWS 'commando' lower, post-ban I can use.  I also have an A3? flat top upper.  However, to get them cerakoted would be about 160.  There is a local place (Houston) called Cerakoters, strangely enough, that charges 80 for an upper or lower.  However that also puts me at the price I see some Aero Precision blems at on there sale page.  So it seems silly to have them coated, I could save them for a pistol build, and just get the set from Aero.

Then there is option 2.  I have another lower I bought, which is heavier duty build.  from Armitage/SOCOM.  When I put the A3 upper on it, you can see how much thicker it is.
Dont ask me why I chose blue.






Second.  I want to go adjustable gas lock on this.  I want that for tuning to loads, possible suppressor, and wear and tear and accuracy.  That of course entails a light weight BCG, lighter springs, etc.

So here is the list I came up with.  


Rifle Build
    1. LaRue 20" Stealth 1:8 M4 medium (.750) w/ gas tube               260 
    2. Superlative Arms Adjustable Gas Block (.750)                             99
    3. BCM Gunfighter charging handle medium mod 4                         50 
    4. Geissele  SSA-E                                                                          240 
    5. Seekins parts kit                                                                            90  
    6. Faxon Lightweight BCG                                                               249
    7. JP Captured Spring Kit                                                                170
    8. Luth-AR MBA1 stock                                                                   139
Upper/Lower
    1. Aero Precision stripped FDE set                                                  170  
    2. Cerakote my own PWA/whatever                                                160 Cerakoters
    3. Cerakote Diamond/SOCOM Lowe                                                 80
    4. AE Enhanced Upper 12/15                                                            315
    5. Fortis Switch Handguard 12                                                         270    
 
Question.  How does one handle tuning the gas block if their handguard covers it?  Is it easy to adjust through it?  Are some handguards easy on off?  


Any  feedback appreciated.

I do it with the hand guard off, tune in the block for the load and put the hand guard back on.

I would forgo the Luth AR and get a magpul prs. It is 3 times the stock.

also check out Criterion barrels. May say you a few bucks over a LaRue

Possibly stupid question - my speciality, I think - but what do you plan to do with the gun? What do you consider long range? Do you reload?

Will this be a strictly range gun, always from bench or prone, always fair weather?

In most cases, I have a well-defined purpose before a parts list. If this is just a “I want it”, I get that, have done it many times; but if it is a purpose-built gun, knowing the true purpose will help with the directing.

I would probably suggest a different chambering.  6.5 Grendel and the related 6mm Turbo are better chamberings for longer ranges.

Beyond that, RC's question is important: will you be doing positional shooting with it? or only bench/prone?  Will this rifle ever be carried?

That will drive the choice of several of the components.

It isnt my intention to use it for mostly target/bench/paper hole punching.  And yeah, there is a whole lot of I want it.

I do not intend to carry it, go hunting with it where I have to hump it.  I was thinking of a suppressor in the future (or I was with SHARE act).  So maybe it could be used for hog killing.  I also want to assemble something tunable as opposed to the ARs I have now (Armalite AR-15 A2/AR-10TC).  

I do understand that .223 isnt the best caliber for long distance, but I would prefer to see what I can do with that caliber.  I intend to reload and have gotten myself a good starting set of equipment and dies, (.308), but my philosophy is to use up my surplus ammo first and increase my shooting ability before I start loading better than I can shoot.  Yes, I do understand I am talking about something with a twist more suitable to heavier .223 rounds than your standard milsurp.

To be honest I havent contemplated other chamberings than .223.  Also, to be honest I really dont know how important that extra 2 inches is between 18 and 20.  I was assuming its some more fps and very helpful at longer range.

I think I will Google pros and cons of other AR calibers..
Also rethinking my distance remarks, because that is what my .308 is for.
