20 round mags....when you are asking about price...are you asking total price or just the work...the work was pretty cheap. $30 to thread the barrel...$40 to install the handguard.
handguard with my discount $150
DPMS barrel nut $50
Badger gas block $50
Part of my issue was the guy I spoke to at BO...dude was an idiot...I called him 4-6 times to verify...the AR10 stabilizer handguard is sent with a barrel nut for an Armalite AR10...BO makes a barrel nut for the DPMS, but you have to buy it from BO...when I spoke to the guy at BO he said my gas block would fit underneath their handguard...it didn't...so I call him back again and asked which gas block I should use and he had no clue...come to find out later that BO sells gas blocks...so I spend another $50 for the barrel nut and another $50 on the DPMS on a gas block...BO gas block didn't fit on my barrel either...so that's when I decided to send it off to Randall aka AR15barrels...great guy to deal with...and his prices are very reasonable. He installed everything and had my upper back to me within a week...and we are talking about shipping from CA to PA.
If you go to DPMSinc.com one of my groups from this rifle is there...don't mind that I didnt' spelled Medal...metal...these are super accurate rifles. I am debating on doing the same thing to my other rifle.
