Greetings,
Up for sale is a 10.4" cut-down MR556 upper receiver group; barrel cut and nitrided by Jayson at IGF (Investment Grade Firearms) with no profile reduction under handguard. Jayson also installed a legit HK 10" gas block during reassembly. Will also include the standard MR 14.5-20" block. Colt metal dust cover and rod were also substituted for the plastic HK parts (HK plastic dust cover and rod are also included). Pictures below are of complete SBR; only the upper receiver group and buffer/buffer spring are included.
The entire rifle has had exactly 4 magazines (120 rds) fired during one range visit. I am also a member on ar15.com with 100% positive buyer/seller feedback (near 100 transactions). Additional pictures/info will be gladly provided to a serious buyer, as I also have all email discussions with Jayson at IGF concerning the conversion of the upper.
Price for the upper shipped via USPS Priority with tracking and fully insured is $2050;
PLEASE OBSERVE ALL FEDERAL/STATE/LOCAL LAWS CONCERNING THE PURCHASE OF THIS UPPER!! This MUST be paired with a legal registered SBR or AR pistol to be in compliance with the law (including possession and use).
Please use email for communication, and let me know if you have any questions/concerns. Not looking for any trades at this time. This item is cross-posted on other sites as well, so may be sold at any time. THANKS FOR LOOKING!
