Weapon Information

The True Velocity RM338 is a lightweight medium machine gun chambered in .338 Norma Magnum, developed by LoneStar Future Weapons and True Velocity as an evolution of the LWMMG concept. Designed to close the capability gap between 7.62 NATO GPMGs and .50-caliber heavy machine guns, it delivers long-range precision and suppressive fire in a significantly lighter, more maneuverable package.

Weighing approximately 25.5 lbs unloaded, the RM338 provides effective fire out to 2,000 meters. Its Short-Recoil Impulse Averaging (SRIA) system reduces felt recoil and stabilizes the weapon during bursts, enabling controllable automatic fire even with the powerful .338 Norma Magnum cartridge. The platform features a removable barrel assembly with fixed headspace and timing, compatibility with polymer-cased ammunition, and a lightweight folding stock that enhances portability in dismounted roles.

Key features include: Medium machine gun chambered in .338 Norma Magnum, Short-Recoil Impulse Averaging (SRIA) recoil-reducing system, Removable barrel assembly with fixed headspace and timing, Compatibility with polymer/composite-cased ammunition, Folding stock and MIL-STD-1913 rails for accessories and optics.

The RM338 offers long-range suppressive capability that exceeds traditional 7.62 NATO machine guns while avoiding the weight and bulk of .50-caliber platforms. Its combination of extended reach, reduced recoil, and lighter overall weight makes it suitable for dismounted operations, overwatch roles, and any mission demanding controllable automatic fire at extreme distances.

Raw Recordings

Our raw shots features a total of 28 channels including 13 Stereo and 2 mono sources. All of our close and mid spaced pair Microphone options can be used as two independent mono microphones. The right side of every spaced pair will have more Mech than its left side counterpart.

Every single gun has been recorded using the same gain settings on the same recorders, and we have level matched each microphone option between the same calibers so your 50ft microphones will be the same or similar across all libraries that share the same calibers. This makes mixing large amounts of weapons easier as the loudness and character of each gun is predictable.

Our foley features a total of 4 audio channels with 1 Stereo and 2 mono sources, including the Sanken CO-100k which captures frequencies above 100kHz for extreme pitch shifting workflows.

Designed Mixes

We included 3 sets of designed mixes:

Building Blocks:
Our Building Blocks mixes are lightly designed assets which are specifically created to give you a jump start in designing your own gun shots if you don’t want to work with the raw assets.

Modern Mixes:
Inspired by some of our favourite games we’ve crafted an aggressive mix which not only includes a composit mix but also includes the individual layers (Shot, Mech, Tail, Atmo, & Trigger Pull).

Realistic Mixes:
We have also included 3 realistic mixes designed by our recordist so that you can hear exactly what this gun sounded like from the shooters prospective.

Suppressed Recordings

In addition to the unsuppressed shot recordings, we’ve also sampled the RM338 with a suppressor attachment. The suppressed RM338 was sampled right after the unsuppressed recordings using the exact same microphone setup as the unsuppressed version. This provides you a seamless transition between the unsuppressed and the suppressed recordings.

The suppressed recordings also have the added benefit of muting the shot layers which helps bring out the intricate details of the mechanism (mech layers).

Because adding a suppressor to the firearm increases the weapons muzzle velocity, the fire rate of the suppressed weapon is slightly faster than its unsuppressed counterpart.

All Future Updates For Free

With the purchase of the Master Gun Armoury Bundle you will receive all base library updates for free which can include us recording new samples for the library, re-sampling the entire library with more microphones, new designed mixes, metadata updates, etc.

Why Deliver 32-Bit Float Shots?

There are several advantages in using 32Bit float recordings. One of which is having greater separation from the explosion of the gun and the mech. Because of this, you’ll be able to isolate the mech from each gun and bring out each guns unique characteristics.

32Bit Float files require a slightly different workflow than you might be used to. Other gun sample libraries that use 24 Bit recordings already come pre-compressed/clipped and will be louder than our libraries. when you are working with 32 Bit Float gun recordings you’ll need to compress/clip the recordings in order to get the same loudness.

Metadata

One of the most powerful features included in the Master Gun library is its extensive metadata and tagging. Every single field has been filled out. Every library is compatible with all major sound library management software including Sound Miner, Baeshead, Soundly, etc.

To take advantage of all the metadata features we do recommend using Sound Miner.
