I could really use some advise. I have decided that I want to buy a 10.5 Noveske upper. My question is should I spend the extra cash on the Noveske Lower, or would it be ok to use the Stag lower that I have been running problem free. I have heard that the are made by the same company, not sure if that is true or not. I would rather spend the evtra money on the stamp unless I would sacrifice function with the stag. Thanks
More than likely you would be fine with the Stag lower, however there have been reports of low QC at Stag re: out-of-spec lowers.
IMO I would just drop the extra change to have the Noveske lower to go with the upper.
Besides a Noveske complete rifle has some major CDI 
I would go with the Noveske lower. Get a complete Noveske package. You won’t regret it.
you can get a complete LMT lower for 330 bucks.
might be worth a look.
