Make new magazine models for "extended mag"

Right now if you use the extended mag attachment the model of the magazine stays the same, the literal magazine stays looking like a 30rnd mag yet it holds 35. May we get an actual 35rnd mag? Wait a minute, I just did some research and literally could not find any company that makes 35rn mags, only 40 rounders for the 556/223

Maybe we should get real 40rnd mags with 40rnds in it. Apparently, 35rnd mags don't exist. 40rnd mags please, go big or go home

I've always assumed this was coming. I hope it is...
