Length is 11.25” relaxed, 24 coils.

The internal depth is 7”.

Here are some images of my extractor. Here is the buffer kit I bought and specs Buffer Length: 2.5" Buffer Weight: 3.8 oz. https://www.aeroprecisionusa.com/m5-308-carbine-buffer-kit-1

My mistake, I am using Gen M3 MagPul.

I did use ALOT of lube and I currently have 2 20rd promags.

Hello All, I am about 2 months late in posting this but I have finished my build. Thank you all for your suggestions and steering me clear of what would have created some headaches in this process. I have since gone to the range twice, mainly to zero my scope, but both times have experienced multiple misfeeding issues on about the 2nd or 3rd shot (each time I am only loading 5 rounds at a time). The first time at the range I was shooting cheap Tulammo and figured that might have played a roll in the misfeed and failure to eject the emptied casing causing a jam feeding the next round. This last weekend I fired 20 rounds of 7.62x51mm L2A2 ball ammo (which was gifted to me by a friend and is probably older than I am) and 10 rounds of Winchester 7.62x51mm M80. With both the L2A2 and M80 ammo I experienced a jam and a misfeed. What would you guys consider my issue to be? I believe I can rule out the quality of ammo I am running. Does this sound like a gassing issue and sound like I should try out an adjustable gas block? I am currently using a AP low profile non-adjustable one.

Thank you Gentlemen for all your advice. I have ordered based on all your suggestions and would have been done by now but the Aero barrel nut that came with my handguard came packed with a AR15 barrel nut and not the M5 barrel nut that it was suppose to. That should arrive tomorrow and once assembled sometime this weekend I plan on posting photos. In the meantime my hunt for .308 ammo has been rough. I have only managed to acquire 80 rounds of TulAmmo (which I do not plan to shoot anytime soon being steel) and 40 rounds of Hornady Black which I would prefer not to use as target ammo initially. Because of the panic and ammo shortage I have entertained the idea of reloading. What are your thoughts on reloading,? I too have been informed that materials for loading is in short supply as well but from it doesn't appear as scarce as ammo. Poking around the below link seems like a viable solution to beginning reloading. https://www.midwayusa.com/product/1022385415

haha true

You referring to this one? https://www.graniteridgeoutfitters.com/Aero-Precision-M5-308-Enhanced-Quad-Rail-Handguard-Gen-2-APPG308224.htm

Thank you Karo, I made another list and the upper didn't get transferred. Stripped upper receiver 114.74 https://www.primaryarms.com/aero-precision-m5-308-stripped-upper-receiver-apar308503?quantity=1&keywords=apar308503 Thank you for that trigger suggestion. That will make a great replacement. Ugh! I cannot find an aero handguard anywhere. Would the below lower parts kit suffice? https://www.aeroprecisionusa.com/m5-308-lower-parts-kit-minus-fcg

Hello there, I'm a newbie to building rifles. I am currently in the process of building an AR308 and hoping to joins a community who can help steer me clear of any potential headaches.... which sounds all too common with this type of build.

Hello Gentlemen, I am in the process building my first rifle and need some advice. Since there is a chance Biden might win and ban all online sale of guns/ gun parts so it is probably a good idea that I build my rifle now. I have sourced the following parts from various venders and would like to be sure that all the components are paired correctly, I have not sourced an sights for this. Not only that I would like to know what parts I might be missing or unnecessary, again first timer here. My desired build is for an 308 chambered mid range rifle, so I hope that I am on the right forum. link Forward Assist Assembly https://www.ar15part.com/308-AR10-Forward-Assist-Assembly-Kit-p/faa308.htm Ejection Port Dust Cover https://www.primaryarms.com/aero-precision-ar-308-ejection-port-cover-kit-aprh100107 Charging Handle https://www.primaryarms.com/aero-precision-ar-308-charging-handle-aprh100125 Gas Block https://www.primaryarms.com/aero-precision-low-profile-gas-block-750-set-screw Barrel (w/ out extension) https://www.primaryarms.com/ballistic-advantage-ar-10-308-16-mid-length-barrel-5-8x24-babl308003m barrel guard https://www.cheaperthandirt.com/guntec-ar-15-freefloat-handguard-15-m-lok-aluminum-black-gt-15mlk/FC-714569645946.html Safety Selector Lever https://www.primaryarms.com/expo-arms-ar-15-ambi-safety-selector Safety Spring & Detent https://www.midwayusa.com/product/1003339888 Trigger & spring https://www.primaryarms.com/cmc-ar-15-ar-10-drop-in-duty-single-stage-4.5lb-curved-trigger-mil-spec-.154in Hammer & spring https://www.midwayusa.com/product/1003326576 Disconnector & spring https://www.midwayusa.com/product/1003337737 Bolt Catch (roll pin incompatible) https://www.primaryarms.com/aero-precision-ar-308-bolt-catch-aprh100134 Bolt Catch Spring & Plunger https://www.primaryarms.com/ds-arms-bolt-catch-plunger-zm48634 Magazine Release Button https://www.primaryarms.com/odin-works-xmr-extended-magazine-release-black Pistol Grip, Screw & Washer https://www.primaryarms.com/hogue-ar-15-m-16-overmolded-pistol-grip-with-cargo-management-black-ho15010 Takedown Spring and Detent https://www.midwayusa.com/product/1003335390 Bolt carrier group https://www.cheaperthandirt.com/aero-precision-3087.62-bcg-with-forward-assist-phosphate/FC-815421020144.html Castle Nut https://www.primaryarms.com/anderson-manufacturing-mil-spec-carbine-castle-nut-am-26 Stripped lower receiver https://www.primaryarms.com/aero-precision-m5-gen-ii-308-stripped-lower-receiver-dpms-cut-apar308003?quantity=1 Stock https://www.primaryarms.com/magpul-acs-l-carbine-stock-mil-spec-black-mag378-blk pivot pin https://www.primaryarms.com/aero-precision-m5-308-pivot-pin I would appreciate any input or critique to the proposed part list.
