They have our initials on the butt of pistol grip area, and our names engraved in the floorplates. Otherwise, they are hard to tell apart, and we mixed them up a couple times while cleaning and shooting them this last weekend. It has been a fun project for us and we look foward to using them this fall.
You will really like the Manner's stocks. These have the carbon fiber shell, so most of the weight is in the butt. The rifles balance pretty well for their size. On the bipod, they just kinda float and are very stable. When you get them, Tom has the painted and finished already, they just need bedded. I wish the his OD green would have matched a little better as it would have eliminated that step. The only thing I have noticed, is that on most of his stocks, the ejector port isn't quite long enough. I lengthed these to match the action so it looked a little better.
TMR, I have started to gather the components for my 338LM build and am looking at the McMillan A-5 versus the Manners T-2 or T-4. I have a Stiller TAC 338 and a Broughton fluted 1-10 twist that goes 1.25 for 6" and will finish at .9 at 30". I will be using either Seekins or Badger DBM. Any input on the Manners versus the McMillan? By the way, beautiful rigs.
