Pick up a Winchester Featherweight or compact FW and check the boards for the take off DBM's minor if any fitting with them. I would check with SAC for the work and he may even have them in. The FN TBM's are just out so people may be selling the older 4round DBM. Flush fit and quiet.
How bout pick up a used rifle with a pinned or integral lug and dbm and have a light contour barrel chambered for it and now you got a rig to run and gun and a light wt hunting rifle with everything mag release bolt handle/angle all in the same place,feel, etc
