Re: Question
It all depends on your personal preferences of feel. We had the A-4 stocks on the M40A3 and I personally liked a lot about it but others hated it. First is going to be your shooting position in general. With the spacer system and the saddle cheek piece you can get a pretty good personalized length of pull and cheekweld. I'm not too familiar with the AI system though I have shot a couple. The AI 1.5 is your fixed version and pretty much you can do the same crap with it on the position. The thumbhole vs. vertical grip is basically your only change. I'm unsure why you hate the HS precision stock but it all depends on their model. The non-adjustable ones leave a lot of changes to the shooter but their HS pro-ser. 2000 heavy stocks are nearly the same as the MCM. On the McMillan A4, my buddies that didn't like it had that opinion because of the bulkiness and the squareness. At the ass end, it's a great stock, but some of them felt it was overkill for stability and in all honesty that's true. McMillan came out with the A-5 which eliminates the squared off front and keeps the rear the same. From an accuracy standpoint, all systems are going to be good. With good marksmanship and a solid receiver and barrel you'll get half minute accuracy out of them all. If you do go with the McMillan, get it glass bedded with MarineTex. This will epoxy-mate the receiver to the stock and eliminate any accuracy issues you would have with a chassis or pillar bedding system. The AI is chassis (full length bedding block style) system and some of your HS Precisions are alluminum pillar bedded. Ultimate in accuracy is going to be your glass bedding. So, my personal opinion is go with the McMillan but go A-5 instead of A-4. Hope that helped.
