Toolbox
Interactive calculators, video analyzers, and compatibility checkers for the bench, the range, and the build sheet.
Build Cost Calculator
Pick a purpose and a quality tier. Get an itemized AR-15 build sheet with live 2026 component prices, no guesswork.
Pistol Red Dot Fit Checker
Select an optic-ready handgun and see compatible red dots from the catalog, including direct-mount, footprint, and adapter-plate matches.
Shot Timer Video Annotator
Upload a shooting video, detect shot times locally from the audio track, correct markers, and export synced split-time overlays.
Loadout Weight Calculator
Calculate carried weight across rifle, magazines, plates, helmet, comms, night vision, medical, bags, tools, and every catalog gear category.
Pistol Red Dot Height Checker
Pick a pistol, optic, and plate to see stock-sight co-witness, recommend optic-height irons, and preview the ADS sight picture.
Rate of Fire Video Overlay
Detect shot peaks from a range video, correct markers, calculate burst RPM, and export a clip with a synced rate-of-fire HUD.
Recoil / Return-To-Zero Analyzer
Upload side-view or first-person video, track muzzle or optic movement, measure recovery time, and compare two setup changes.
Ejection Pattern Video Analyzer
Upload a slow-mo rifle clip, detect brass ejection angle and apparent throw distance, then map the result to gas and buffer fixes.
Target Photo Scorer
Upload a target photo, auto-detect scale and impacts, correct markers, then measure group size, POI shift, MOA/MIL, and score rings.
Photo-to-Loadout Cataloger
Upload a range-bag photo, auto-identify each visible item, link catalog matches, and flag missing support gear like medical and ear pro.
Buffer Weight Calculator
Input your barrel length, gas system, and ammo type to get the exact buffer weight recommendation for reliable cycling.
Gas System Troubleshooter
Step-by-step diagnostic wizard to identify and fix cycling issues, failures to eject, double feeds, and other gas-related problems.
Ejection Pattern Analyzer
Diagnose overgassing or undergassing by matching brass ejection to the classic clock-face chart.
Barrel Range Visualizer
Compare effective ranges and velocity drops for different barrel lengths (10.3" to 20") across multiple ammo types to match your mission.
Ballistics Calculator
Calculate bullet drop, wind drift, and trajectory from 0-1000 yards. Supports preset ammo profiles and custom BC/velocity entry with environmental corrections.
Zero Distance Visualizer
Compare trajectory curves for 36/300, 50/200, and 100-yard zeros to understand point-of-impact at any distance up to 400 yards.
Offset Zero Calculator
Calculate required point-of-impact offset for different zero distances (36/50/100/200 yards) at your chosen range distance.
Zeroing Click Calculator
Convert your point-of-impact deviation (inches) into exact turret clicks (MOA/MRAD) for any target distance.
Optic Selection Wizard
Answer questions about your engagement range, astigmatism, and night vision needs to get a personalized optic recommendation.
Rate of Fire (ROF) Calculator
Analyze burst RPM, shot spacing, and timing from audio clips. Great for measuring your rifle's performance or comparing buffer setups.
Lower Receiver Compatibility Checker
Search 45+ manufacturers to see if your lower receiver's fire control pocket is compatible with Super Safeties (M16 vs Low Shelf vs High Shelf).
Test Your AR-15 Knowledge
Thirty questions across ballistics, gas systems, optics, and build theory. Personalized guide recommendations from your results.
