"Ripoff" is a loaded term, and implies that Smith & Wesson is intentionally trying to gouge their customers. This is not accurate.

The 811034 SKU is not a ripoff. It is an option that Smith & Wesson offers to those who want to save some money on Magpul accessories they would have purchased anyway for their rifle.
If this SKU were not available, then to replicate it you'd need to buy the 811033 SKU and then add:
Magpul MBUS Rear sight - $55.00
Magpul MBUS Front sight - $38.00
Magpul MOE stock - $57.00
Magpul MOE pistol grip - $21.00

This is a total of $171.00 in additional parts.
The MSRP price difference between the 811034 and 811033 SKUs is $90.00, saving you $81.00. This is a great deal and you should absolutely purchase the 811034 SKU...

...only if you want the Magpul MOE gear.

If you don't, then it would be silly to buy that SKU. Fortunately, Smith & Wesson offers other SKUs to meet your needs.

Personally, I like the feel of the MOE grip better than the A2 grip. I also like the stock better than the standard M4 stock. The MBUS I ended up moving to my BCM 5.56, so that saved me money there too.

It's not a "ripoff".
