I bought one LWRC when they were giving away the Aimpoint T-1. You had to buy a new M6 Individual Carbine and have your FFL file out a form and mail it with a photocopy of the 4473 to LWRC. About three or four weeks later they'd ship the T-1 to your FFL for pick up.
My T-1 came with the riser and LRP mount. I was very pleased. The rifle I bought had an AAC muzzle device (added $100) and was factory Ceracoated (added $150) so out the door for a new LWRC M6 IC Enhanced with 14.5" spiral fluted barrel / pinned in place AAC 51T flash hider / Patriot Brown Ceracoating AND a NIB Aimpoint T-1 with LRP Mount was about $2300.
The free optic dropped the price of the rifle to around $1,700.
The promotion ended August 31st.
I bought my other LWRC (remember I preach redundancy in primary arms) three days before the promotion began. LWRC would not give me an Aimpoint for that one
