SKU: N/A Categories/Brands: ,


This covers cutting/crowning as well as threading. This service is for any AR15/AR10 barrel once it has been removed from the receiver, or any STRAIGHT barrel. AR barrels with the FSB in place are covered under this service/fee. This service also covers handgun barrels that need standard threads. that do NOT need to be extended. Threads will be concentric to the bore. If you want the barrel shortened note length in the comment section. in This service also covers stripped barrels of other varieties. If the barrel will not drop through a round hole with a diameter slightly larger than that of the barrel, you need to select the non AR15 threading service. If sent as a complete upper, the Disassemble/Reassemble service is required as well. Gas port work is included when necessary. When barrels are cut, they are all measured from a closed bolt face as the only standard measurement we use.

    Had my 18″ rifle length Daniel Defense barrel but down to 16.25″ and the gas port enlarged to .120″(included in cost). Was back at my door within 2 weeks of dropping it off at UPS. Everything was perfect and the threads were just as good if not better than they were from the factory. My rifle runs perfectly. Will use adco again

    Sent my Rock River LAR8 (308) Predator 20″ barrel to ADCO to be threaded for a suppressor. They threaded and re-crowned. It shoots better than it did before I sent it to them. All I can say is the crown must of had an issue. Thanks to ADCO for great work. I would recommend them and will be using you again in the near future.

    5 stars isn’t enough for these guys. Had a factory BCM upper disassembled (which is an absolute pain), barrel chopped to 14.5″, suppressor muzzle device pinned and welded, and was all done and back at my doorstep in 6 days. Could not be happier with the work, service, and turnaround time. Would definitely recommend ADCO and will be using them again in the future.

    Did exactly what I asked and did it well. I’ve had barrels sit in local gunsmith shops for longer with unsatisfactory results. ADCO does awesome work. Make sure you read the FAQs prior to shipping, luckily they didn’t extend my turnaround time after I used a little tape to hold pieces to the barrel. I highly recommend ADCO.

    I have had three barrels worked on so far with excellent results. A factory 700P 26in cut down to 24in and threaded for 5/8×24. it now groups better than ever. The others were ruger 10/22s threaded for 1/2×28. I am about to send out another barrel to be re worked. I recommend these guys to anyone I talk to who wants to get work done.
