Drifter

I'm seeking a Mega Maten rifle-length monolithic quad upper receiver for a build. Will pay top $, or trade a new standard Maten upper receiver plus cash. Just thinking there might be someone out there who might no longer want / need their rifle-length monolithic quad. Please PM me if you have one you might consider parting with (or know a retailer that has one). Thanks (My Maten upper receiver is for trade towards specified item only. Not for sale otherwise.)

I'm considering a build in 260 or 6.5 CM on the DPMS platform, and this would be my first venture into the larger AR's. What are current options to purchase match grade barrels? Any info would be appreciated. Thanks
