A friend today, offered a like new GGG 30mm scope mount, for free if I paid the shipping. The agreement was if I do not like it, send it back. How on earth can I say no to that!? It's the bolt-on variant. 5.5 ounces. SPR Rifle Scope Mount | FLT Scope Mount for Special Purpose Rifle Available in QD and Bolt-On (http://www.gggaz.com/flt-scope-mount.html) Are they any good? Anyone have one that can share comments? I'll soon find out. I wish this offer would have come to light before I ordered the LT104!
