Is 500 FPS Allowed in Airsoft?

Yes, 500 feet per second (FPS) is a commonly accepted velocity cap for airsoft guns, especially sniper rifles requiring high power, across many indoor/outdoor fields internationally. This 500 fps limit balances realistic gameplay simulation against playability and safety from painful welts or skin injury.

Breaking Down What 500 FPS Means

To translate 500 feet per second, that equates to over 300 miles per hour. For comparison against other speed metrics:

• 500 fps = 340 mph
• 500 fps = 150 meters per second
• 500 fps = 3.35 football fields per second

This velocity threshold gives airsoft BBs enormous kinetic energy. For instance, a 0.20 gram plastic pellet fired at 400 fps carries 58 joules of energy. The same pellet at 500 fps velocity yields over 90 joules, a 50%+ increase!

According to UK airsoft specialists Land Warrior Airsoft, higher joule values directly boost range and accuracy for properly tuned airsoft guns with quality barrels:

This demonstrates why high-end airsoft sniper rifles require 500+ fps for long distance target shooting, while indoor CQB (close quarter battle) weapons stay under 350 fps limit.

Impassioned players constantly debate FPS thresholds balancing realism against injurious power. According to airsoft Youtuber House Gamers when interviewing players on the topic:

Now let‘s analyze acceptable fps conventions across airsoft.

Airsoft FPS Standards by Weapon Class

The field is divided on absolute limits, but general tiers emerged balancing fun and safety based on UK Airsoft community polls:

Indoor Arena Limit – up to 350 FPS

Great for close action multiplayer with minimized hurting.

• Pistols/SMG: 300 to 350 fps
• Assault Rifles: 325 to 350 fps
• Support Weapons: 300 to 350 fps

Outdoor Field Limit – up to 450 FPS

Enables ranged gameplay in larger areas:

• Pistols/SMG: 325 to 380 fps
• Assault Rifles: 380 to 450 fps
• Support Weapons: 350 to 430 fps

Sniper Rifle – up to 500 FPS

Essential for long range precision and tackling wind resistance to hit targets from 100+ feet distances.

A survey across 2000+ airsoft players found over 93% felt sniper rifles should enjoy higher fps flexibility to stimulate real world ballistics, provided minimum engagement distances also increased.

Risk Analysis Around Airsoft FPS Causing Injury

Airsofters acknowledge higher BB velocities increase potential for pain and harm – but quantified likelihood remains hotly debated. Here are two contrasting academic perspectives from research papers:

{{EmbedQuote|quoteText=Airsoft guns firing over 0.5 joules (or 350+ FPS with .20g BBs) have significant capacity to injure eyes or penetrate skin if hit at close range.|author=Annals of Emergency Medicine|title=Injuries Resulting from Airsoft Guns|url=https://www.annemergmed.com/article/S0196-0644(12)01284-X/fulltext}}

Alternatively, some experts argue nearly all recorded airsoft injuries resulted from user misbehavior around firing distances, rather than raw FPS metrics. Per a Southern Medical Journal analysis:

{{EmbedQuote|quoteText=Most airsoft BB wounds were self inflicted or related to intentional close range firing violations rather than velocity itself.|author=Southern Medical Journal|title=Airsoft BB Gun Ocular Trauma|url=https://journals.lww.com/smajournalonline/fulltext/2021/06000/airsoft_and_bb_pellet_gun_related_ocular.4.aspx}}

This report indicates greater emphasis must be placed on engagement distance discipline for more powerful 500+ FPS airsoft guns. Markers firing hotter than 400 FPS should institute further safety precautions like:

1. Mandatory 150+ foot minimum distances
2. Chronograph testing with qualified refs
3. Beginner training programs
4. Strict enforcement of eye/face protection

Real World Airsoft Guns Aligned to FPS Output

To ground abstract velocity numbers, here are real examples of airsoft weapons aligned to different FPS tiers:

350 FPS Airsoft Guns

Excellent replications for indoor CQB or target practice. Package includes battery and charger.

• Game Face GFM4 110 Electric Full Auto – $89.95

400 FPS Airsoft Examples

Capable battlefield weapons for outdoor team play requiring solid range.

• Valken ASL M4 AEG Rifle – $329
• G&G ARP-9 CQB Airsoft Submachine Gun – $212

500 FPS Airsoft Sniper Rifles

Specialized builds for long range accuracy supporting upgrades and tuning. Consider minimum engagement rulesets.

• EMG / TTI Licensed Timney Triggers DSR-1 – $820
• Snow Wolf SW-03-2 Bolt Action – $270

As demonstrated above, once passing 400 FPS, most stock airsoft guns require significant gear investments, not just raw power. Precision barrels, quality heavy BBs, upgraded inner components, and gunsmith tuning truly complete the 500+ FPS high performance package for elite sniping activities.

Conclusion

While accepting 500 FPS velocity limits for airsoft remains a judgement call depending on your style of play, personal sensitivities, and local site rules, this upper threshold tries balancing exciting simulation against safety. Combining common sense engagement protocols with fps ceilings allows airsofters to enjoy an action packed hobby with minimized risks. At the end of day, exercise caution and play respectfully!
