So are you building a SBR or a rifle? I have a 12.5" barrel pistol and a 12.5" rifle with a 4" muzzle brake. Both shoot pretty well.

There is no milspec for the large platform AR's. Most are either Armalite pattern or DPMS pattern. As long as the upper and lower is from the same manufacturer things usually work out. Stag, Diamondback, Wilson Combat, Windham, DPMS, Daniel Defense all sell quality guns.

Who's carbine buffer system? What does the buffer weigh? What is the internal depth of the buffer tube? What spring are you using? Your barrel length and gas system length doesn't really matter if you have the proper gas port diameter for the length barrel balanced by the recoil system with the proper weight buffer and spring. The buffer should weigh close to 5.5 oz .

Happy Thanksgiving everyone.

Knew I forgot someone. Mikedaddyh thanks for the help w/my tent. Blue thanks for the help w/my tent also.

Welcome from KY. Lots of luck w/that buffer.

Vice, 2 45acp cases and a pin punch All you need. Maybe an extra pair of hands. 1 case over tail of the bolt. 1case in the head. Tighten in vice Remove pin(s) Loosen vice.

Great meeting you too. Yeh it's fun but at about fifty cents a round it adds up quick.

When I got home there was still a dusting of snow on the ground. Been in the teens at night. 34 w/a wind-chill of 22 right now.

It was great meeting all the new to me folks and seeing the old ones again. Magwa the skill and patience it takes to make those points is incredible. Unforgiven sorry you couldn't stay a bit longer. Sketch you brought some cool toys. Canuckgoucho a real pleasure. Doc and Susan glad I finally got to meet yall. Thanks for the warm bed. Rsquared it was a pleasure. Matt always a pleasure. JB Matt keep Tom on his toes at the matches. Tom and Kim thanks for everything. Great folks to hang with. If I left anyone out it's my bad memory.

What he probably meant is the herters ammo is loaded light. You turned up the gas so it will function. NOW your gas is turned up too high for the brass ammo to function correctly. Your bolt is running to fast for the brass ammo. Less gas or more buffer mass should get the thing running with brass ammo.

Well i made it home. Abilene Tx to Bagdad Ky one long day. Im going to bed. Might go shoot some deer this afternoon.

Great times. Almost halfway home. Between Sweetwater and Ft Worth. Going to bed. Found @Rsquared a sprit tree.

Welcome from KY. It was nice meeting you.

Your recoil system needs to Ballance out the BCG and gas system. Your spring and buffer need to be bigger. The 5.4 oz buffer and springco orange spring is the right way to go.

Think Lone Wolf McQuaid has one of those wraiths. I have an ATN first gen that I'm not real impressed with.

Used to go out to the west coast almost every week in the big truck. Didn't leave anything there I need to go back and git. I might consider going in far enough to visit DNP but that's as far as I go.

This is the one I bought. I moved it to my 6ARC pistol I built. https://www.natchezss.com/optics/rifle-scopes/45-18x40mm-ar-optics-black-illum-wind-hold-box-5l-bhar741840ei This what I replaced it with. https://athlonoptics.com/product/argos-btr-gen2-6-24x50-apmr-ffp-ir-mil-copy/

Good glass is expensive but good glass almost always comes with a lifetime warranty. You only buy it once. You can always put it on another gun down the line. The Bushnell AR series scopes have been on sale a lot of places. I have one on a rifle. When it was on another rifle I hit steel at 800 yds. The 1" tube ran out of elevation and I had to use the reticle to get the rest of the elevation. Inside 500 yds the scope works fine.

We also have veterans day next week.
