AK patterened rifle parts and accessories

Aftermarket 12-gauge furniture and hardware for the three most common pump-action platforms: Mossberg 500/590, Remington 870, and Maverick 88. The core of this category is Magpul's SGA stock line — an adjustable, drop-in shoulder stock in Black, FDE, Gray, or Orange for the 870, and Black or FDE for the 500/590.

Stocks and grips by platform

• Mossberg 500 / 590 — Magpul SGA adjustable stock, or a rear pistol grip for a compact configuration.
• Remington 870 — Magpul SGA in four colors (Black, FDE, Gray, Orange).
• Maverick 88 — ATI Shotforce PG buttstock with an integrated pistol grip.

The SGA stocks add length-of-pull spacers (12.5" to 14.5"), sling-swivel cups on both sides, and replaceable cheek risers so the same host can wear a bead sight for hunting or an optic-and-extended-tube setup for defensive use. The Maverick 88 Shotforce is a one-piece drop-in.

Everything ships free from 3CR, and every stock and grip drops onto the OEM receiver — no gunsmithing. If you're upgrading a different host, browse other rifle and pistol platforms, add a sling with slings and mounts, or grab a soft case from cases and bags.

Parts and upgrades for the 1911 platform — Government (5"), Commander (4.25"), and Springfield's double-stack Prodigy variant. Most of the stock in this category serves the classic Government-size .45 ACP host, with sights cut for Colt and Novak dovetails.

What fits which 1911

• Slides — Ed Brown Government 5" .45 ACP stainless slide cut for the Trijicon RMR, and a Commander 4.25" slide with dovetail sight cuts. Slides ship as housings; barrel, sights, and internals are separate.
• Sights — Trijicon HD Night Sights in orange or yellow front for Colt 1911 dovetails, Trijicon fiber-optic sights for the Novak rear cut, and TruGlo Brite-Site TFX for a 3" host.
• Muzzle devices — a 1911 Government 5" .45 ACP compensator for reduced muzzle rise on the range gun.
• Optic mounts — Springfield AOS mounting plate for the Holosun 509 on the 1911 DS Prodigy.

Verify sight cut (Novak vs. Colt), frame size (Government / Commander), and caliber before you buy — 1911 parts are host-specific and not cross-compatible with striker-fired pistols. Free shipping at 3CR. See compensators for other muzzle brakes, other pistol platforms for non-1911 upgrades, or cases and bags for range storage.

Sights, triggers, magwells, and slide accessories for the Smith & Wesson M&P platform. We carry parts for the full-size M&P 1.0 / 2.0 and the M&P Shield — including the Shield Optics-Ready cut — sourced from Apex Tactical, Trijicon, TruGlo, and Tyrant Designs. Free shipping on every order.

What fits which M&P

• Night and fiber-optic sights — Trijicon HD, HD XR, Night, and Suppressor-Height sets are cut for either the standard M&P 3-Dot, the M&P Core (optics-milled slides), or the M&P Shield. Match the sight to the slide cut, not just the model name.
• Triggers — Apex Action Enhancement kits drop into the M&P Shield; Tyrant Designs CNC triggers replace the OEM trigger on M&P 1.0 and 2.0 full-size frames. Both reduce pre-travel and break weight without altering trigger geometry.
• Magwell and mag extensions — Tyrant CNC magwells fit the M&P 2.0 Full Size; the +5 magazine extension adds capacity to factory M&P Full-Size mags.
