Practical guides to AR-15 fitment, optics, triggers and weapon lights, written for UK shooters. Filter by topic below, or email us if your question isn’t covered.
Mounting
Bore height decides how your rifle comes up, whether your irons appear in the optic window, and how far low the round strikes up close. Here is what 1.54in, 1.63in and 1.93in actually mean, and which one suits your rifle.
Stocks
Collapsible AR-15 stocks come in two diameters and only one will fit your rifle. Here is how to tell which buffer tube you have before you order.
Practical Rifle
Speed of manipulation over everything else — charging handle, ambidextrous controls, foregrip, optic height and a light handguard for Practical Rifle.
CSR
What CSR shooters actually run on a straight-pull AR — stock and length of pull, sling and sling mounts, iron sights, handguard and grip.
Straight Pull
Straight-pull ARs take the same furniture as any AR-15 — but one part catches people out. What fits, what varies, and how to check before you order.
B5 Systems
Why the US Army picked B5 Systems to build SOPMOD stocks — and how the Bravo, Enhanced SOPMOD, Collapsible Precision Stock and Type 23 P-Grip fit your build.
Bravo Company USA
Bravo Company USA's Gunfighter line explained — Mod 0, Mod 1 and Mod 2 grips, SOPMOD stocks and kits, and the KAG angled grip.
Upgrades
Ten proven AR-15 upgrades under £100 — grips, stocks, sights, sling mounts and more, ranked by how much difference they make per pound spent.
Charging Handles
Why ambidextrous controls make every AR faster — and how the Radian Raptor charging handle and Talon safety selector upgrade your rifle's two most-used controls.
Triggers
Single-stage or two-stage? Drop-in or standard? Pull weight, pin size and the brands worth knowing — everything you need to choose the right AR-15 trigger.
