October 2025's Arena Breakout Infinite meta has crystallized around four standout weapons: the versatile S-Tier FAL and close-quarters MPX, the precision A-Tier M110, and the budget-friendly B-Tier AK102. Here's everything you need to know about builds, ammo choices, costs, and when to deploy each setup.
What's Driving the October 2025 Meta
Let's be honest—this meta is all about punching through Tier 6 armor. Period.
The FAL has claimed its S-Tier throne as the only assault rifle that can chamber T6 M61 rounds, delivering a devastating 682.5 damage with 714 penetration. That's not just impressive; it's game-changing. The MPX shares that S-Tier spot for completely different reasons—its 850 RPM fire rate combined with near-zero recoil when properly configured makes it an absolute monster in tight spaces.
Season 10 brought some welcome changes to the M110, bumping its fire rate from 400 to 425 RPM. Doesn't sound like much? Trust me, those follow-up shots feel noticeably snappier. It's earned its A-Tier ranking.
The AK102 sits comfortably in B-Tier—not because it's bad, but because it's the sensible choice. Controllable recoil, affordable mods, and solid performance make it the weapon you recommend to your buddy who's just getting serious about the game.

Current Weapon Hierarchy

S-Tier: FAL (mid-range versatility with T6 support) and MPX (CQB dominance at 850 RPM) A-Tier: M110 (long-range precision with improved 425 RPM and two-shot T6 capability)
B-Tier: AK102 (budget-conscious choice with solid upgrade potential)
Here's what I've learned after hundreds of raids: ammunition tier matters more than your base weapon quality. If you're running anything below Level 4 ammo in competitive play, you're essentially bringing a water gun to a firefight.
AK102: The Reliable Workhorse

The AK102 chambers 5.56x45mm rounds at 600 RPM with an 80m effective range and 55 damage per shot. Single-fire and full-auto modes give you flexibility.
Budget AK102 Setup
Cost: 15,900-21,000 Koen for modifications (57,000 Koen complete) Gunsmith Code: 3fOafNDUYLQszi4
You'll want: AK-100 30-round magazine, lightweight AK grip, PT1 stock with adapter, AR Universal compensator, AK Polymer handguard, and AKM gas block.
Pair this with T3 M855 ammunition (510 damage, 111 penetration). It's the sweet spot for cost-effectiveness against most armor types you'll encounter.
Premium AK102 Configuration
Cost: 147,000-150,000 Koen for modifications (356,000 Koen complete) Gunsmith Code: 3fOafNDUYLQszw4
The premium build includes: RPK-16 stock with Carbine International, AK Industrial grip, 5.56 specialized compensator, AK Rail system, Lightweight Vertical grip, and Blue-Violet Laser.
Step up to M855A1 (490 damage, 175 penetration) or M995 (420 damage, 265 penetration) for high-tier raids where you expect serious opposition.
AK102 Ammunition Breakdown
M193 (T1): 520 damage, 71 penetration—only for budget runs against unarmored targets
M855 (T3): 510 damage, 111 penetration—the optimal cost-performance ratio
M855A1 (T4): 490 damage, 175 penetration—reliable against Class 4 armor
M995 (T5): 420 damage, 265 penetration—when you absolutely need to punch through heavy armor
M110: The Precision Platform

The M110 chambers 7.62x51mm at 425 RPM with 130m effective range. Two-shot potential against T6 armor with significantly better handling than bolt-action alternatives.
Budget M110 Build
Cost: 48,000-50,000 Koen
Essential components: M110 20-round magazine, Generation 2 Collapsible stock, Lightweight AR grip, Standard barrel, Tactical rail system, Lightweight Tilted grip.

Cost: 111,000-130,000 Koen
Premium setup includes: Extended barrel, M110 Suppressor, AR Extended stock with Carbine components, 4.1 Modular with Vertical grip, Tactical charging handle.
The extended barrel significantly increases your effective range, while the suppressor reduces your audio signature—crucial for those stealth eliminations that keep you alive longer.
M110 Ammunition Strategy
BPZ (T3): 552.78 damage, 213.12 penetration—cost-effective for low-tier raids
M80 (T4): 539.46 damage, 279.72 penetration—balanced performance across scenarios
M62 (T5): 472.86 damage, 352.98 penetration—the high-tier standard
M61 (T6): 432.9 damage, 452.88 penetration—maximum penetration when nothing else will do
FAL: The Versatile Powerhouse

The FAL's ability to support T6 ammunition while delivering 924 damage with UN rounds (or 682.5 with M61) makes it special. 630 RPM, 124m effective range, 7.62x51mm chambering—this is serious stopping power.

Performance Comparison: What Actually Matters
Damage Per Second Reality Check

The FAL hits hardest per shot (682.5 with M61) but that moderate 630 RPM limits sustained DPS. The MPX? Exceptional sustained damage through sheer volume of fire—850 RPM compensates for lower per-shot damage.
The M110 excels at burst damage with two-shot T6 capability, though you're limited by semi-automatic fire. The AK102 offers balanced 600 RPM with moderate damage for sustained engagements.
Range Considerations
M110: 130m effective range, extendable with barrel modifications FAL: 124m base, achievable 168m with extended barrel
AK102: 80m effective range for close-to-medium engagements MPX: 57m effective range—purely close-quarters optimized
Cost-Benefit Reality
Budget builds (15k-50k Koen): AK102 remains most affordable, M110 requires moderate investment, MPX costs more but delivers exceptional performance, FAL commands premium pricing.
Premium builds (130k-485k Koen): MPX demands highest investment (485k), FAL offers expensive pseudo-sniper capability (380k), others scale moderately.
Situational Loadout Recommendations
Close-Quarters Combat
Indoor environments demand high fire rate and mobility. Primary choice: MPX with 7N31 ammunition for face shield penetration. Alternative: FAL with short rail and laser attachments. Budget option: AK102 with lightweight modifications.
Pro tip: Target legs with Dumdum ammunition against heavily armored opponents to bypass armor entirely.
Medium-Range Engagements
Mixed terrain requires versatility. Versatile choice: FAL with extended barrel for 168m capability. Budget option: AK102 with M855A1 for Class 4 penetration. Precision alternative: M110 for two-shot armored targets.
Switch to single-fire beyond 50 meters for accuracy and ammunition conservation.
Long-Range Precision
Open terrain favors precision platforms. Primary: M110 with extended barrel and M61 ammunition. Alternative: FAL with thermal optics. Support: AK102 for follow-up shots.
Practice those recoil patterns extensively before deploying expensive configurations—trust me on this one.
Budget-Friendly Meta Builds
Entry-Level Configurations
AK102 Old Reliable (57,000 Koen): Focus on essential recoil modifications, T3 M855 ammunition, prioritize ergonomics over premium attachments.
MPX Leg Shredder (88,000 Koen): Target unarmored parts with Dumdum ammunition, emphasize mobility, utilize that high fire rate.
Smart Attachment Choices
Maximize performance per Koen spent: grips and stocks provide significant recoil reduction, basic compensators offer substantial control, standard magazines provide adequate capacity, iron sights eliminate optics costs.
Value Optimization Tips
Ammunition First: Invest in higher-tier ammunition before expensive attachments
Incremental Upgrades: Gradually improve builds rather than jumping to premium configurations
Match Your Opposition: Adapt investment to expected threat levels
Recovery Planning: Use budget builds for gear recovery operations
Advanced Optimization Strategies
Min-Maxing Approaches
Recoil Pattern Mastery: Practice specific ammunition and attachment combinations, develop muscle memory for different engagement ranges, utilize the firing range for pattern recognition.
Ergonomics Optimization: Balance weight reduction with performance gains, prioritize ADS speed for competitive advantages, consider mobility for tactical positioning.
Competitive Build Variants
FAL Juggernaut (380,000 Koen): Maximum recoil control, T6 ammunition for guaranteed penetration, thermal optics for target acquisition.
MPX Silent Killer (485,000 Koen): Suppressor for stealth operations, extended barrel for improved ballistics, laser systems for hipfire accuracy.
Role-Specific Configurations
Professional adaptations vary by role: Entry fraggers prioritize mobility and close-quarters effectiveness. Support players emphasize range and sustained fire capability. Flankers focus on stealth and rapid elimination potential. Anchors optimize for defensive positioning and area denial.
