Up for sale is the above pictured HK MR556A1's Lower. Comes with 2 HK Mags, Custom-fitted Wilson TTU 4# trigger by Hubrich Gun Works of Allentown, PA.
If you're not familiar with the Wilson TTU Combat Trigger, it may be the best single stage duty trigger available. 4lb break, crisp and clean. The reset is VERY short, and some have reached 400 rpm semi-auto with this trigger. The factory trigger unit was decent at best, a rather smushy two-stage trigger very unlike the G36/UMP or the 9x series. This trigger brought the entire weapon system together, IMO. The below video (not me or the MR) shows how quickly one can fire with this trigger system.
The gun came to me NIB, never fired. She was well taken care of. I put exactly 420 rounds of XM855 Ball down the tube, and cleaned well. [B$999[/B] No trades, USPS MO only. PayPal +3%. Willing to accept silver or gold as partial payment.
I've had interest in just the upper. If I have interest in the lower, I'll consider splitting.
Complete upper $1725 shipped (Upper, VFG2, BCG, Buffer, Spring, 1 Mag)
Complete Lower $999 shipped (Minus Buffer & Spring, + 2 mags, Wilson TTU) –– SPF
Will only part once I have two interested parties. I have one possibly interested party for the upper at the time of posting, hence this post!
