Hey gents in need of some advice on a rushed mistake. Recently picked up my first bolt gun Rem 700 sps in 308. Bought the Mark 4 base and Mark 4 30mm medium height rings after some research on here. Figured this was a good entry level set up to start working on my distance shooting. Went with the Nikon m-308 4-16x42 with the BDC but in my own stupidity didn't pay attention that it uses the 1inch rings instead of the 30mm that I bought. Badger ordnance makes ring reducers that will make my mistake not such a costly one. Any cons with going this route ie loss in accuracy, failure to maintain a consistent zero etc. Thank you for your advice.
