View Full Version : FAL / G3 Combo Franken FALG3
February 03, 2009, 17:50
Have been thinking of a combiination of parts for a build:
FAL gas system - IMI large barrel gas block
HK G3 barrel with no flutes in the chamber
Fabricated rail system to act as guide for bolt (G3 parts)
The big question> will the G3 delayed roller blow back function from the G3 function with the FAL gas system (gas piston pushing the bolt to unlock from the trunion).
Would make for a shorter back end ( idea is to make a Walther WA2000 of sorts, that is a bullpup design ). The lack of a rat tail or spring/tube out the back end would shorten the distance.
Any Ideas or am I going to spend much time and materials?

it has already been under thinkage ...thunkage ...whatever ...hehe .id just lose the gas system and install the trun and round barstock in the receiver internals for the hk carrier guides ...chargehandle in same place as fal carrier .the hk CH set up is re-diculous ..lota stuff there to just pull back a bolt .......what are ya waitin for ...off ya go .show pics ..hehe ..i agree a blow back fal would be sweet ....nice big fat bully on it ..die milk jug DIE !!!!!!.hehehe :)

Nothing Ventured, Nothing Gained. Do it, and take pics.
As far as time and materials, hope you've got plenty of both.

If you use the standard HK trunion, carrier, bolt head, and rollers the system will still try to function as a standard HK. However, without the flutes in the chamber the shell will stick in the chamber and the extractor will try to rip the base off. This is what Mauserwerke had when they developed the first StG45 prototypes - before they added the flutes to the chamber.
Realize that both the bolt and carrier on an HK system start recoiling (only by a few millimeters) while the chamber is under full pressure. If you add a gas system to assist in unlocking the bolt (by accelerating the carrier to the rear) you could possibly end up unlocking the bolt while there is still dangerous gas pressure in the chamber.
The only way I would consider this idea would be if you could modify the system so that the rollers were actually locked - not interfacing with angled surfaces on the carrier and trunion - then you might have something feasable.
