Magpul Starter Kit: Stock, Sights, Mag — Then Stop
Stock, backup sights, and magazines. That is the Magpul cart that changes how an AR handles before you disappear into bipods and pouches. A Magpul CTR matched to your receiver extension, MBUS 3 rear sights as backup to a red-dot, and PMAGs in your caliber cover the basics.
Start with the stock: CTR mil-spec
If you have lived with a rattly, worn-out AR stock, you know why the CTR became the default upgrade. Magpul’s friction-lock system takes the wobble out of a mil-spec adjustable stock. The listing we stock is the Magpul CTR Carbine Stock, mil-spec, black.
Mil-spec here means it fits a mil-spec receiver extension (buffer tube) — not a commercial-diameter tube. Measure or check your tube before you order. Wrong diameter is a return you do not want.
Backup sights still matter
A red-dot is great until the battery dies or the optic takes a hit. Folding backup irons behind the optic are the boring insurance that still works. We stock MBUS 3 rear sights in black and olive drab green. Same sight, two finishes — pick what matches the rifle, not what looks cool in a cart screenshot.
If you already run tall irons you like and they cowitness cleanly, you do not need to buy MBUS just because this post named them. If you have a naked rail and a new optic, put backups on the list before the fifth hand stop.
Magazines you’ll actually reuse
One good polymer magazine pattern beats a drawer of mystery mags. In stock today: Magpul PMAG 30 AR/M4 Gen M3 in 5.56 / .223, black — 30-round Gen M3, about 7.5″ and 5 oz on the listing. Buy what your state allows; capacity rules are yours to know, not ours to invent.

What not to buy first
Skip the deep Magpul rabbit hole until the rifle runs: DAKA pouches, bipods, every MOE variant in every color. Stock that locks up, sights you can fall back on, and mags that feed — then stop and shoot. Specialty furniture is easier to choose once you know what bothers you on the clock.
