FN FAL Lower and upper question

Hello to all,
As I have become more familiarizes with the FN FAL, I have noticed that many of the complete Belgian rifles that were originally imported into the USA, the upper and the lower receivers do not match the corresponding profile. The lowers look to have the profile to match a type 1 or 2 upper, but yet the majority of the uppers are a type 3. Does anyone have a reasonable explanation as to why this took place, thanks...

FN continued to use type 1 cut lowers throughmost of the late production. IIRC, they did make some cast type 3 lowers, but offhand I don't think I've ever seen a commercial FAL that had one.

In other words FN switched to a type 3 upper as a cost saving move but continued to use up stock of 1 and 2 cut lowers instead of trashing them because they didn't match.

Even when they switched to the Type 4 in the 1980s they still were using Type 2 lowers. paco did post pics of some Type 4 lowers, so they definitely made some of those. Not sure if FN ever got around to making Type 3 lowers in-between.

Isn't a type 4 simply a cast type 3?

There are some additional differences. I have a cut Type 3 and the corners at the rear of the rails for the charging handle slide are beveled and the thinning of the mag well walls on each side is cut and done in the same manner in terms of shape, radius, etc. as earlier receiver types.

FN Type 4 are cast; IMBEL are not AFAIK.

From what I recall of the lower posted, the differences in construction were more substantial. I'd have to find the thread.

Found the thread on the lowers. Looks like they cast them as one piece instead of assembling them from multiple parts and included the channel for the rivet on the para cover in the casting, and use the pistol grip screw like DSA does.

Am I correct that all FN Type III's are cast?
