The M4A1-S | Blue Phosphor in Factory New (FN) takes in almost the whole range of the finish: its scale ends at 0.08. The wear itself lies between 0.00 and 0.07. The skin is Classified rank and belongs to the Control Collection. It has never dropped from any case.
What the M4A1-S | Blue Phosphor looks like in Factory New
The blue here is metallic and laid on in several layers over a chrome-blue base, which is how Valve describes the method. In shadow the color falls to almost black, and cold, nearly white highlights run along the ribs and edges.
Everything is painted, magazine and grip included; only the barrel under the handguard is left bare. That makes the rifle read as one solid blue piece, with no colored accents and no pattern.
In Factory New the highlights are sharp and the deep blue is not diluted by gray. From 0.00 to 0.07 the look changes little, and listings at either end resemble each other. On Minimal Wear the receiver edges and the top of the magazine are the first to cloud.
Where the M4A1-S | Blue Phosphor came from
The finish belongs to Valve itself, and its catalog number is 1017. The Control Collection opened in the game on December 3, 2020. On the same day Valve announced Operation Broken Fang and wrote in the note that the weekly mission rewards would include new weapon collections.
The second Classified skin in the set is the USP-S | Target Acquired; the other ranks in the collection sit lower.
What to check before buying
The choice comes down to these points:
- the float within 0.00 to 0.07: on mirror blue, clouding is visible even at light wear;
- the receiver edges and the top of the magazine, where the highlights vanish first;
- any name tag or stickers that come with the lot.
What the M4A1-S | Blue Phosphor costs in Factory New
The starting price for this wear is shown by the listing block above. Minimal Wear costs about one and a half times as much as Factory New here, even though it looks worse. The reason is how the scale is laid out. The top wear got the stretch from 0.00 to 0.07, while the next one got only 0.07 to 0.08, an eighth of the range.
In Factory New the M4A1-S | Blue Phosphor is third by price among fifteen Classified skins for the model. Only the M4A1-S | Hot Rod and the M4A1-S | Knight rank higher. The nearest below, the M4A1-S | Master Piece, is almost half the price.
Getting the M4A1-S | Blue Phosphor
A contract for the M4A1-S | Blue Phosphor is made of ten skins of the rank below from this same collection. The Control Collection has two Classified skins, so the odds of landing on this rifle are one in two. The condition of the result is set by the condition of the inputs.
The skin works as an input too: the next rank up in the set holds the AWP | Fade.
StatTrak and Souvenir
Stickers and craft on the M4A1-S | Blue Phosphor
No StatTrak version of the M4A1-S | Blue Phosphor was ever issued. Souvenir copies exist, though no packages were made for this finish: they were made only for the tournament map collections. Such copies are built through the Souvenir-O-Matic, which applies gold tournament stickers and a player autograph to an ordinary skin from your inventory.
Deep blue with white highlights makes a dark background, and yellow, white and orange stickers read better on it than the rest, while blue and purple ones get lost. The body has few flat places, being all ribs and bevels, so for a CS2 craft people use the stock and the receiver.
Who this wear suits
Buying the M4A1-S | Blue Phosphor specifically in Factory New is sensible when:
- you want an inexpensive way into the finish: the second wear is priced higher;
- you want the sharp edge of the highlights, which blurs on a scuffed body;
- the rifle is being matched to a blue set in CS2.
The choice between the two wears is short: Factory New is both cleaner and cheaper, and the finish simply has no other version.
