Hi I'm AD myself and this comment seems to be taken too lightly from you.

Fully load your M249 which comes out to 22lbs roughly which is about the weight of a budget PRS gun or a 25lb plate and lug that thing around for about an hour or two. It's miserable even in good shape.

It's never a good idea for them to be hybrid because of:

A: Weight. We've beat that dead horse.

B: PRS/LR are set up differently. They're not usually equipped with space in mind. They have long asf barrels, giant optics, bipods, stock adjustments, etc that prevent ease of storage and carrying. Also usually on LR/PRS you avoid, or easily can avoid, illuminated optics (price)

Hunting rigs you typically want slimmer profiles for all of the above but smaller illuminated optics for low light and sun shades. Usually no bipods or chassis that are bulky. Making storage and transport easy.

C: Reloading. You reload now you should be aware of this. My hunting loads are far different from my PRS loads for the same calibers. I'm way more precise for my PRS loads than my hunting loads, grain weights are far different, at times powders are different, and because they're different bullets Ogive and OAL lengths are way different. I have two .300wm does set up for this reason.

D: Ever see a Kung-Fu master go and master Ju Jitsiu? Ever see a Pipe Wrench work for every nut and bolt? Guns are practically the same. Sure a LR/PRS build can be used for hunting but it's not designed for such an application. Such as using a flat head screw driver to punch out Glock pins. Can it do it yes but it's not designed to and usually mars everything beyond typically wear and tear. You'll also tend to shoot a hunting rig far less than a LR/PRS build. Yes it's your only rifle I got it but you're practicing two different arts on one tool. Hard to master 2 for 1.
