Re: Rem 700 sps tac conversion to detachable mag
If you're keeping the hogue stock then you'll be limited to assemblies that have the same footprint as the Remington BDL. This means HS Precision and Wyatt's Outdoors are your only options and both have their downsides. The HS Precision is expensive but a quality piece that uses proprietary mags that are expensive and sometimes hard to get. The Wyatts DBM is less expensive but also uses its own mag design in 5 and 10 rounders. Additionally because the mags essentially have to be single stack, single feed in order to fit a 10 rounder is huge.
My advice would be to run the standard BDL and upgrade stocks to something like a B&C or a take off HS Precision that crops up in the F/S section. This will set you back about $250 but it's a worthy upgrade, far more than getting a DBM that will work now. Then down the road pic up a DBM system that uses AICS magazines and have the stock inletted for it, generally about a $100 job at most places.
