FYI - Hi, it's that Kel guy checking in. Our staffer in the Colorado office that answers the email has been out for some family issues this week - if you want, drop me a line and I can probably answer your questions instead. As far as the basics on bi-lock install (or for that matter, most competing QD mounts on the market), it's not rocket surgery, but then again, I've seen some real... interesting... install methods in my years here (Elmer's glue, soldering wire, etc). If you're willing to follow the directions, have a torque wrench, and some common sense, you should be able to do it yourself or with the help of a competent gunsmith. We can do the install for $25 plus shipping, which is real good insurance just in case your barrel is out of spec wrt threads... we'll do what needs to be done to fix them. If we do it, you know it's right, or if nothing else, you know who to blame if something does go wrong. That might be $25 bucks well spent right there!
That HALO obviates a bit of this, without the added cost of the bi-lock FH, so that may factor in to some decisions. The D model is going up in price for 2005 - we've had three straight years of raw steel prices going up on the supply end and haven't raised our prices for years - but we're freezing the HALO at the price it's at. I personally feel the HALO offers the best bang (or lack thereof) for the buck right now. Current -D owners, feel free to get a smug look that you got in before the increase. :)
Thanks,
Kel
