If they don't deviate some from the MOD specification there will be some rifles the barrels cannot be fitted to. Then people will be back to using rings to take up the space at the shoulder when the metal on the shoulder could have been left long.
With the exhaustion of Britishicon military ammo the only ammo close to fitting the huge chambers well is the stuff made by PPU. The #4 barrels would benefit from having smaller diameter chambers unless you just want everything as mud proof as an original. With the large chamber case life will be shortened.

It's the last 20 years where I learned WTF was going on! I was told recently that I work Lees the exact opposite of all common sense training to thousands of gunsmiths graduated from the Colorado School of Gunsmithing. That's a real scary thought. I'll be real disappointed if the engineers at Criterion deviate from basic MoD specifications on these things and make them way more complicated than they have to be. I think if they stick to the KISS theory, all will be well. I reckon we'll see.
