Feel Improvement: Feels more ergonomic and comfortable during long sessions or winter use.
Giessele Super Modular MK16 Rail - Mount Accessories

Available for 9.3", 10.5", 13.5". A2 front sight must be removed first and low profile gas block is required for installation.

Geissele Super 42 Braided Buffer Spring - Improved Spring Service Life
While the default Rock River Arms buffer tube is serviceable. we recommend upgrading to the Geissele Super 42 Braided Spring, along with an H1 or H2 buffer for a 16" standard gas system.
Inspired by the German MG42 machine gun’s recoil spring. This reduces the "TWANG" sound and vibration you normally feel/hear with a standard spring. It also makes the spring more robust – if one strand would fail (unlikely), the others still provide force to chamber the next round.
Benefit:
- Smoother cycling with reduced twang.
- Stronger spring ensures consistent feeding.
- Paired buffer softens recoil impulse.
- Can take the increased cyclic wear
Feel Improvement:
- Action feels smoother and quieter; recoil is more controlled and less abrupt.
- No TWANG in the buffer tube
