Scream'n 318 ?

been considering this my self but figured it be considered butchery!! one issue with stock rollers is there heavy as is, adding a slug just gonna add to that!

Here is a weight comparison I did a while back.

Crane solid body roller pair: 239.3 grams
Comp solid body roller pair: 268.5 grams
Magnum rollers: 303.2 grams, I weighed 2 together for comparison.

The Magnums were new replacements by Melling with no oil in them.

Going by this, 1 mag lifter is 32 grams heavier than 1 Crane, 17 grams heavier than 1 Comp.
