### Key Specifications
- **Manufacturer**: CMMG
- **Model**: Resolute 300
- **Type**: Modern Sporting Rifle (AR)
- **Caliber**: 9mm

### Features

The Geissele SSA is a two-stage mil-spec trigger with a clean break and predictable reset, a meaningful upgrade over standard AR triggers. The RipStock adjusts for length of pull, which matters for fitting the rifle to different shooters or shooting positions. Barrel twist rate is 1:10.

Running 9mm in an AR-pattern rifle reduces recoil compared to rifle calibers and keeps ammunition costs lower. The 33-round capacity means fewer reloads during range sessions.

> Trust me, the rifle is very easy to shoot. It snaps through 9 mm rounds with only a fraction of the recoil one might expect.

> I have definitely had some failures to extract which have resulted in a traffic jam of empty casings lodging themselves deep into the 5.56 size creass.

> If you are a left-handed shooter, I do not recommend this gun. It is simply not made for us.
