So i have an oppurtunity to purchase 5 ars from my buddy that are just parts... all magpul furniture and poly upper and lower. And the price (under 650) each. I have done about 5 lowers so i knowni can do that. But anyone know a decent shop in the ocean county area besides shore shot(hate that place) that can put the barrel on the reciever? I can handle everything else

Just insert the barrel into the upper, and torque down the barrel nut between 35-75 ft lbs. AR barrel wrenches run about $50 or less.

You know that you need a barrel extension on an AR barrel correct? Once that's in place, the system is plug and play.

Willing to sell some parts?

both of my ar barrels came with barrel extensions/m4 feedramps already installed, if yours did your good. you may be charged something ridiculous by a smith to attach the barrel to the upper, so you may want to give it a shot yourself it doesnt require much

I got 5 tries to get it right. So i guess ill order a wrench and vice block today. Thanks for the help

Need a torque wrench if you wanna get it right.  For the barrel nut, tighten, then loosen twice to 30 foot pounds. On the third tighten set it at minimum of 30 Foot pounds, then line up your gas tube.  Don't forget to lube upper threads with a little moly wheeelbearing lube at the least or a small tube of airplane lube if you can get it.

i bout a 1/2" torque wrench from harbor freight. cant beat it for 12 bux compared to 50 bux at Lowes. mine has held up fine, no complaints

 

I used moly grease for both my barrrel nuts........sounded dirty for a second

Lol ok

I come from a mining and farming family.  Have seen wheel bearing grease slathered in places you would not believe.  We all survived just fine.
