FN rebooted the SCAR 16S 17S 20S for 2026 with a hydraulic buffer, extended receiver, and true suppressor focus. We shot them side by side, and the improvement is instant.
What Changed on the Next-Gen SCAR 16S 17S 20S
FN officially pulled the cover off its updated SCAR lineup today, introducing revised versions of the SCAR 16S, SCAR 17S, and SCAR 20S alongside new FN QD suppressors designed specifically for the platform. While the rifles keep the familiar SCAR profile, FN focused heavily on shootability, suppressor compatibility, and consumer-driven updates.
All three new SCAR variants share the same core updates. The biggest change comes from a redesigned, hydraulically buffered two-piece bolt carrier that noticeably reduces recoil and smooths out the impulse. In my shooting time behind the rifles, recoil felt reduced by roughly half compared to earlier SCAR models. The difference is not subtle. Follow-up shots came faster, and the sharp impulse of the original SCAR was replaced with a softer, more controlled push.
Each rifle also features an extended receiver with an integrated M-LOK rail system, fully ambidextrous controls, true AR pistol grip compatibility, updated triggers, and suppressor-ready muzzle threads using U.S. standard patterns. FN also reworked the gas system to better support forward-venting suppressors, including the new FN QD556 and QD762 models arriving in Q2.
SCAR 16S: Lightweight 5.56 That Shoots Incredibly Soft
The SCAR 16S remains FN’s 5.56x45mm carbine option, but it now shoots noticeably softer than before. During testing, shooting doubles on a silhouette at 50 yards felt easy and controlled, even after extended strings. Roughly 150 rounds went downrange with no issues, though the handguard did heat up quickly after about 30 rounds. Recoil stayed mild throughout, reinforcing the updated bolt carrier’s impact.

SCAR 17S: .308 That Feels Way Less Mean
Chambered in 7.62x51mm or 6.5 Creedmoor, the SCAR 17S benefits heavily from the recoil-reduction updates. Despite being a .308, the rifle felt smooth and manageable, even during faster shooting. FN kept the familiar heavy-carbine feel but improved control and suppressor readiness without adding unnecessary complexity.
SCAR 20S: Semi Auto Precision to 1,385 Yards
The SCAR 20S continues as the precision-oriented option, available in 7.62x51mm and 6.5 Creedmoor. On steel, it delivered hits from 200 yards all the way out to 1,385 yards. At 1,000 yards, I went 2-for-2, showing the semi-auto platform does not sacrifice precision. The updated two-stage trigger and hydraulic buffering made staying on target easier during extended strings.
When You Can Buy the New SCARs and QD Cans
FN plans to release the SCAR 17S in limited colors in Q1 2026, with additional colors following in Q2. The SCAR 16S and SCAR 20S are scheduled for Q2, along with FN’s new QD suppressor lineup.
