in a word NO...

you can make the modification to everything but the fluting in the barrel with aftermarket parts and come out ahead

I managed to build an MOE from parts offline for $75 less than the MSRP and i still have the OE grip and stock to swap on if i sell it

same thing goes with the PC model...if its used and under MSRP then hit it up! if its not...build your own--thats the beautiful thing about this community and these guns--the personalization
