The GDR416, it has all the same training weapon features of the original GDR15, but is based on the iconic HK 416D in short barrel 10.5" flavour.
As with all things GBLS the build quality of GDR416 is nothing but spectacular as you would expect from this training weapon.
The GDR416 has the correct upper and lower receiver, straight mag well and increased height upper receiver with the RIS rail system locking tin to place on the top rail.
The differences between the GDR15 and GDR416 are the following
Forged from solid AL-7075 aluminium (a first for a production airsoft gun) the details are CNC machined then finished with a Milspec Type III Hardcoat Anodizing
The TD style grip is double-shot injection moulded DuPont Zytel PA66-GF30
The crane style stock has been developed for perfect fit with the buffer tube and maximum battery space. Made from double-shot injection Moulded Dupont Zytel PA66-GF30 and a urethane pad and metal QD insert
A highly detailed replica of the classic quad rail system, the handguard is extruded AL-6063 aluminium, CNC machined and Type III Hardcoat Anodized. It also features a welded block for the retention screw just like the real thing.
The GBLS DAS system is hard to describe as it uses a gearbox in the lower receiver which interacts with a full size moving bolt in the upper as you would find in a GBBR platform.
