Will PE90 Upper swap onto CQB? Or does anyone know who has Rails in stock?

[Albertagunnut]

Just wondering ..... I really want a true Flattop upper on my SIG CQB ....Will a Classic green Or black special Ex PE90 upper swap out onto my CQB? or is there a differance between these uppers?

I guess i might just go with the TSE rail or one of the few other makers.... Does anyone have any of these in stock? Help Redleg, Others who know?

Cant find anything i want somedays ....Dont you hate that..

Lol thanks for any help guys

I read when they were importing the CQB's that they were specifically made so that the uppers were not interchangeable. This allows the owners of the "long" rifles to avoid finding their rifles restricted by bureaucratic decision (if the short top half fit, it could be argued that the rifle is too easily convertable to "baby hurting, ultra-evil, kitten killing size" so should be restricted) Also I believe the CQB is registered by the upper, not the lower, so you couldn't have 2 guns fitted together.

Yeah i have heard about the uppers being non interchangable to .....But iam not 100% sure myself... Id just really like to hear it from the Horses mouth... Its really 2 bad TSE never could have brought in some Flattop CQB version....

Maybe could order a stripped 552 Flattop upper.... TSE redleg?

The uppers on all of them are the registered receiver.
