This could be a stupid question (look whose asking it, after all!), but: would anything stop someone from snagging a cheap 700 SPS, a $40 youth stock, dropping it in, and chopping the barrel? Seems like the action and barrel channel would all be fine as long as it was SPS to SPS? (I'm not a Remington guy so this is relatively foreign to me!)
No problem at all. Only slightly complicated issue is if you're going ADL to a floor plate model, make sure to get the right triggerguard/floorplate assembly.
I am a big fan of swapping the trigger out for a Timney on the off chance of losing the Remington safety lottery.
