AIM Engineering rifle chassis systems are precision-built aluminium rifle platforms designed and manufactured in South Africa for hunters, PRS competitors, and long-range precision shooters.
Replacing a traditional rifle stock with an AIM chassis delivers improved rigidity, better ergonomics, repeatable shot placement, and a fully modular platform that grows with your shooting setup.
AST Ballistics stocks the full AIM chassis range including the Delta, Delta .22, Alpha Elite, and Bravo .22 — along with all AIM accessories — with units manufactured per order and delivered nationwide across South Africa.

Custom-built precision rifle chassis systems, manufactured per order in South Africa. Lead time: up to 21 working days.
The AIM Delta Chassis is the flagship competition-grade platform in the AIM Engineering range. Built from aircraft-grade aluminium, it is designed for PRS, long-range, and precision shooting disciplines where stability, repeatability, and platform rigidity are critical. The Delta features a fully adjustable buttstock, ergonomic pistol grip, M-LOK forend integration, and customisable rail options — delivering rock-solid performance across all centrefire calibres. Available in multiple colour finishes, manufactured per order in South Africa.
Colours available: Black, White, FDE, Green, Burnt Bronze, Gun Metal, Grey
The AIM Delta .22 is a purpose-built rimfire chassis designed specifically for .22LR platforms, bringing competition-grade performance to South African NRL22, PRS rimfire, and training shooters. Starting weight of 2.4kg, with M-LOK weight compatibility allowing scaling up to 4kg — giving shooters precise control over rifle balance and recoil management. If you shoot .22 competitively in South Africa, the Delta .22 is the most capable rimfire chassis available locally.
The AIM Alpha Elite is the hunter-focused chassis in the AIM Engineering range, combining a streamlined profile with full adjustability and modular accessory mounting. Built from aircraft-grade aluminium at just 2kg including grip, it delivers strength without bulk for South African hunters navigating bushveld, Karoo, and mountain terrain. The Alpha Elite features an adjustable buttstock with length-of-pull and cheek riser adjustability, fully M-LOK integrated forend, and includes one magazine and a Picatinny rail. The ideal precision hunting chassis for South Africa.
The AIM Bravo .22 is a competition-grade chassis built specifically for .22 rifles, designed for NRL22 competitors, PRS-style rimfire matches, and serious .22 shooters who want a top-tier platform without the centrefire price tag. Delivering the look, feel, and performance of a full competition chassis, the Bravo .22 is the go-to choice for South African rimfire competitors looking to upgrade their shooting platform.
AIM chassis accessories improve stability, comfort, and rifle control for precision shooting applications. From M-LOK weight systems and monster weights for improved rifle balance, to the AIM monopod, bolt knob, recoil pad, cheek piece, and polymer magazine — every accessory is designed to integrate directly with AIM chassis systems for a fully customised precision shooting setup.
