The M16's receivers are made of 7075 aluminum alloy, its barrel, bolt, and bolt carrier of steel, and its handguards, pistol grip, and buttstock of plastics. Early models were especially lightweight at 6.5 pounds (2.9 kg) without magazine and sling. This was significantly less than older 7.62 mm 'battle rifles' of the 1950s and 1960s. It also compares with the 6.5 pounds (2.9 kg) AKM without magazine. M16A2 and later variants (A3 & A4) weigh more (8.5 lb (3.9 kg) loaded) because of the adoption of a thicker barrel profile. The thicker barrel is more resistant to damage when handled roughly and is also slower to overheat during sustained fire. Unlike a traditional 'bull' barrel that is thick its entire length, the M16A2's barrel is only thick forward of the handguards. The barrel profile under the handguards remained the same as the M16A1 for compatibility with the M203 grenade launcher. The rifle is the same length as the M16A2.(Info from wikipedia)
The Vectorium3D collection features low poly models optimized to look great but render fast.
Ready for games or real-time applications. Even when poly-restrictions are not a factor, optimized low-poly models render faster and make scenes easier to work with.
Vectorium3D low-poly models are fully UV-unwrapped, non-overlapping, with quality texture maps featuring consistent level of detail.
It's possible to achieve more realistic results with procedural shaders, advanced lighting and renderers - but those improvements come at a significant cost in terms of render time. We worked with basic materials only, no procedural maps, no Fresnel shaders, no advanced lighting – all optimized to keep render speed fast yet produce quality results.
Models are to scale (or very close), all materials are well named, all texture maps are well named and organized, all reflection maps (if used) reference the same map so you can easily change reflections on all materials - and we took care to test the converted formats to insure the conversions were successful. We're confident you'll find the models easy to work with and customize to your needs.
We're confident the models will import correctly, take a minimum amount of effort to integrate and customize in your scene, and will render well. If you encounter any difficulties or require the models in another format, let us know and we'll do our best to help quickly - we know the deadline is always near. Thanks for your business!
