I am thinking of buying an AR. Currently in Canada for SBR AR's there is not much selection but I have narrowed it down to a few. LMT 10.5" Defender 2000 and either a 11.5" or 14.5" Sabre Defense XR15. I can't find any 14.5" LMT's so 10.5" is my only option. What do you guys think? I am kinda looking to have a M4 style AR so I was kinda hoping to go with 14.5" but the LMT is in stock and the Sabre Defense is a couple months out.
