Aliens: Fireteam Elite

This one is apparently simpler than I thought. It seems you only need 1 attachement for every type of weapon.

That is to say, you need a muzzle, scope, and mag for an assault rifle, sniper, shotgun, smg, pistol and a mag, barrel, and armature for a heavy weapon.

Some weapons in the same category dont share any attachments, like the assault rifles that use all medium attachments and snipers that use all large attachments.Some weapons share attachments (for instance the revolver and pistols share everything except the mag, but the revolver and heavy weapon share a mag.) So as long as you have one attachment for every weapon listed, you should be good.

I fear this achievement is glitched - can anyone confirm?

I have all of the attachments that are purchasable. Even when I use a "Form an attachment" card I get another card - not an attachment. I have collected them all - right?

The wording of the cheevo suggests you only need one of each type? (not ALL the attachments) ie:

1x Scope
1x Mag
1x Muzzle
1x Heavy weapon arm

I have all of those (obviously) but no achievement. Is there a special weapon to unlock that has a special type of attachment that is unique to 1x gun (that I don't have)

Welcome comments on this. I know this isn't a solution but I thought leaving this here would be seen by others that are looking for this achievement... any help guys?
