The MSRP is higher on the LWR, $2319 to $2150, so naturally the LWR will be more expensive.
Stay safe & have a great day!

From Buds on pricing “Our website updates every 20 minutes, 24/7, with our current inventory and replacement cost. We do not price our guns manually based on our cost in each, rather we use a live download from manufacturers and distributors to set our price based on our current replacement cost. As our cost changes, the corresponding website price of each make/model will change up/down accordingly. Although our profit margin remains unchanged, our advertised prices will change frequently, sometimes several times per day.”

Hi and welcome. Buds prices are tied to stock level and low stock will proportionately increase price until out of stock. The Daniel Defense MK18 has many more units in stock. Price will decrease when items are restocked to higher levels. Cheers, stay safe and enjoy!
