Just want to shout out to Tactical Ordnance for there continued awesome CS I had a question earlier today and was emailed and called in regards, within the hour! I have gone to T.O. prior for a Mesa tactical hyd pistol grip kit, Nordic components +4 ext for my SG and had a great experience. For anyone in the GTA and beyond looking for a knowledgeable, experienced, dedicated gunsmithing service provider, retail, and I believe they provide armourer's courses, you would be doing yourself a disservice if you didn't check here. Just my.02 TY, T.O. For your time and consideration.
