AR15 is a terrible design from the mag well to the bolt handle and the prissy bolt. Tavor is as close as anyone has got to the ultimate rifle to date. 

This really shows what you know.

I would have said the AK but everyone knows that a real man's penis will fall of if he touches a gun with the cocking handle on the right side.

Have you considered that the SCAR (which is made of cheap plastic and extrusions that require almost no post machining, and which sells for about $1100 on the military market last I checked) can't compete with more expensive forged guns LMTs, Colt Canadas, and HKs, and THAT'S why it's "boutique"?

Without some paperwork error from FN Herstal, the French army would have been equipped with FN SCAR-L to replace the FAMAS...

And we bought the SCAR-H PR to replace the FRF2 precision rifle.

In regards to Bren 2 i had some insights and hands-on experience into both early pre production models and couple of months ago with ones made for French GIGN in 7.62, I dont think SCAR was of much influence, the BREN2 was initially designed to be all plastic on both upper and lower  but one of the things Manufacturers learned from G36 is that once you get the metal parts hot plastic upper doesn't aid to shed heat any time soon  hence the redesgn for an aluminum upper. 

The 2 part upper /forend no HK in addition to offering the modularity helps a bit with keeping the heat of your handguard, These all-aluminum handguards without any plastic inserts get hot,i remember one of the test sessions with short barrel BREN2 and there were 20+ of us shooting 3-4 guns, the forends became so hot that you could barrel hold the gun without gloves and we weren't even doing any full auto  

I really have no why they decided to go with 416. They could've decided to get the closest one to their ol' famas in terms of ergo and controls which is the VHS-2. Not to mention it's battleproven as it's been used in Afghanistan by croatian army. And don't get me started with bullpup vs conventional arguments because every rifle designs have their own pros and cons. Just like the endless argument about which is better between AR and AK. It's all about the operator and the training method.

Also i still have no information regarding why the Manufacture d'Armes de Saint-Étienne plant which made the FAMAS closed down? it's a shame they could've just made their own decent designs for example by changing the FAMAS into a gas operated instead of delayed blowback. I know it's possible.

VHS is designed for 2m tall soldiers 

In extruded receiver designs, does the bolt carrier rides directly on the receiver wall or does it need some sort of additional steel railing in the interior for the bolt carrier to rides on?

Usually in an extruded receiver like the SCAR, ACR and BT APC you see some sets of screws.

Yet i don't see any on both the BREN and the 433.

Also how did the barrel mated in the 433? is there any sort of barrel block/trunnion molded directly inside the upper just like the old G36?
Looking at the receiver i don't see any sort of screws outside where the barrel extension is supposed to be like APC, SCAR and BREN

It is supposed to be a quick change barrel so i'm assuming the design is quite similar to the MCX. In the MCX to detach the barrel you just need to loosen a pair of screws that tighten the barrel in place.

lol but it has a retractable stock. Still it all depends on the rifle LOP and so far there's no info on what's the measurement of its shortest LOP which is when the stock is fully collapsed.

It depends. The ACR does have fastened on steel guide rails, but the HK433, CZ Bren 2, and BT APC series do not (I'm not super familiar with the APC series but it looks like what's bolted on the left inside of the receiver is an ejector, not a guide rail. You can see that on the APC9 here:)



I assume that design is a bit different on the APC556/223, but you can see the extruded guide rail right above it.

The SCAR uses the same design, you can see that in the raw extrusions here:

Archangel and Bearcat also use this arrangement.
