Well, well, well...what to redeem ? Check the post description for choices......

What to redeem from the below options :

1). M416 + glider ( I have crow glider as well)

2). M416 + 3 material ( I have total 15 materials so upgrade to hit effect is possible )

3). M416 + its attachments

4). Ultimate set ( I don't have any m4 upgradable skin )

5). Wait and keep gambling 10 UC daily spin till last day and then decide what to redeem ( I have less patience)
