Military AR15 / M16 / M4 Weapons Case B2B Wholesale Procurement Guide: Mobile Armory Style

The protective case market for long guns and tactical equipment is a real B2B segment. Pelican Mobile Armory (472 series) and SKB iSeries with custom foam are the established benchmarks for transit cases that carry a single fully-assembled AR15 / M16 / M4 with magazines, optics, and accessories. For distributors serving shooting ranges, training schools, law enforcement procurement, and the OEM/ODM tactical equipment market, the case for export is a defined product with a defined interior layout, a defined compliance posture, and a defined cost envelope. KeXinMaterials (box-beeaa.com) supplies OEM-grade weapons cases at direct-factory pricing, with custom CNC-cut foam for any rifle layout. 30-45 day production, EXW Shenzhen / FOB Shenzhen / FOB Ningbo, T/T 30%/70%. This 2026 procurement guide covers interior layout, ITAR posture, foam density for rifle barrels and optics, B2B price levels, and the procurement language a distributor needs.

Why a Mobile Armory-Style Case and What Goes Inside

A rifle case is not a foam-lined suitcase. The case has to hold a fully-assembled rifle with optic mounted, with magazines, with the muzzle pointing in a defined direction, without shifting under transit shock, and without exposing the optic to compression load.

Standard rifle layout: a fully-assembled AR15 / M16 / M4 with collapsible stock retracted or extended, optic mounted on the picatinny rail, and a loaded or unloaded magazine inserted, plus 1-3 spare magazines, chamber safety flags, cleaning kit, sling, and a small tool kit. Total length approximately 850-1000 mm with stock extended, 740-830 mm with stock collapsed.

Interior dimensions required: minimum 1000 mm internal length to fit a rifle with collapsible stock extended. Internal width 350-400 mm to accept the optic and the magazines stored alongside. Internal depth 130-180 mm to accommodate the optic height plus foam. Internal volume approximately 45-70 L for a single-rifle case.

The case body dimensions: for an AR15-class case the external is typically 1050-1100 mm long, 400-450 mm wide, 160-200 mm deep. Pelican 472 series sits at this footprint with different internal layouts. KeXinMaterials produces a comparable case in 9 size-class footprints including the rifle-carrier size.

Multiple-rifle case: for two or three long guns the internal length is similar (still under 1100 mm for an AR15) but the internal width expands to 600-700 mm, and the depth to 250-300 mm to accommodate side-by-side storage with foam dividers. Total volume 100-180 L. Common for tactical team deployment.

Optic protection: rifle optics have specific load limits. A 50 mm objective scope under compression can crack the turret housing or push the erector spring out of alignment. The foam at the optic position must be soft PU (15-20 lb/ft3) at 30-50 mm thickness, with a contoured cavity matching the optic body, not just the scope footprint.

Muzzle and barrel protection: the muzzle end should have a closed-cell PE cradle (30-35 lb/ft3) preventing the barrel tip from shifting. The barrel channel runs the length of the case and should be wider than the barrel by 10-15 mm each side to accommodate a barrel-fluting profile or muzzle device.

Bolt and action protection: AR15, M16, and M4 bolt assemblies sit in the upper receiver, exposed at the ejection port. The foam cut must not bear against the ejection port cover — if it does, the cover will dent under transit shock and potentially crack. The foam cut at the upper receiver area must leave a 5-10 mm clearance.

Magazine storage: pistol and rifle magazines should sit in dedicated cutouts at the opposite end of the case from the muzzle, sized so the magazine cannot shift under vibration. A loose magazine in a foam cavity becomes a 200 g projectile on a 1 m drop.

Compliance: ITAR, EAR, and What a Distributor Must Check

A B2B rifle case transaction is not just a foam-lined box. Depending on the jurisdiction, the buyer, and the end use, the case itself or the case-with-rifle transaction may trigger export control.

ITAR (US International Traffic in Arms Regulations): rifles above 0.22 calibre and below 0.50 calibre are USML Category I. ITAR controls apply if the rifle, optic, suppressor, or other accessory is US-origin and the case ships to a non-US end user. The CASE itself is generally not ITAR-controlled, but if the case is shipped containing ITAR items it can become a controlled export depending on the supporting documentation.

EAR (Export Administration Regulations): most commercial sporting optics, accessories, and non-ITAR rifle components are EAR99 or under ECCN 0A501 and ship with a license exception or no license required. Distributors selling complete AR-platform rifles should consult counsel on the classification of the rifle.

End-use statement: a buyer of a 100-unit weapons case order is typically a law enforcement agency, a training school, a distributor, or an OEM. The end-use statement in the order contract should describe the end use, the end customer type, and the destination country. This is not paperwork theatre — it is the basis for the supplier's due diligence and the export compliance trail.

Foreign Military Sales (FMS) and Direct Commercial Sales (DCS): government-to-government sales of US weapons proceed under FMS, and commercial sales to foreign governments proceed under DCS with a US Department of State or Department of Commerce license. A B2B distributor typically operates downstream of both, supplying accessories and cases.

Country restrictions: certain destinations are embargoed for defence articles and dual-use items. The supplier's compliance check covers the destination country, the end user, and the end use. The distributor's contract should mirror these controls.

For B2B case supply specifically: the case is generally not a controlled item. The order can proceed on standard commercial terms. The complication is when the case ships already paired with a controlled rifle — in that scenario the exporter must classify the package.

B2B recommendation: a distributor buying a custom rifle case from a China factory for the US market is the most common case. The case itself does not require an export license. The distributor must ensure that any US-origin component (rigor) placed inside the case is exported under the appropriate license or license exception.

Anti-diversion language: the order contract should include anti-diversion language requiring the buyer to use the case for the stated end use and prohibiting re-export to embargoed destinations.

Foam Density, Hardware, and IP Rating for Rifle Cases

Rifle case foam has to balance impact protection with optic sensitivity. Hardware and sealing matter because rifles and optics do not tolerate moisture or thermal cycling.

Closed-cell PE 30-35 lb/ft3 for the barrel channel, magazine cutouts, and lower receiver cradle: gives structural resistance to impact and prevents the rifle from shifting under transit vibration.

Open-cell PU 15-20 lb/ft3 for the optic cavity and the bolt area: gives soft cushioning for the optic body, scope tube, and the ejection port area. Place the PU layer in the lid or as a removable insert on top of the PE base.

Anti-static foam: in dry climates or winter conditions, static discharge can damage rifle electronics (illuminated reticles, electronic sights). Specify anti-static foam to IEC 61340 for any rifle case that ships with electronic optics.

Stepped / layered construction: PE base layer 30-40 mm, PU mid layer 20-30 mm, optional egg-crate or convoluted surface layer 10-20 mm where items contact the lid. This is the standard construction for premium rifle transit cases.

Hardware: stainless steel pin latches and hinges as standard for the rifle carrier case. Automatic pressure equalisation valve for any case that flies air freight. TSA-approved lock option for cases that will be checked in the US.

IP rating: IP67 (1 m for 30 min) for range and training use. IP68 for tactical-team deployment in marine or coastal environments. EPDM gasket, automatic pressure valve, and stainless steel hardware for the IP68 variant.

Pull handles and wheels: a fully-loaded single-rifle case weighs 8-12 kg. Wheels and a retractable handle are standard for the rifle-carrier case and are an absolute requirement for the multi-rifle case. Specify polyurethane wheels for rough terrain.

UV and chemical resistance: a case carried on a range will see sun, sweat, sunscreen, and CLP. Specify a UV-stable polymer — PP and ABS blend standard. Avoid PVC (chalking and cracking under UV).

Procurement Contracts, End-Use, and Distributor Workflow

A B2B rifle case transaction is more than a one-off order. The end-use statement, the anti-diversion language, and the export compliance trail need to be in the order contract before the deposit wires.

End-use statement in the order contract: describe the end use (training, range, LE procurement, OEM tactical equipment resale), the end customer type, and the destination country. The statement is a binding representation by the buyer and the basis for the supplier's due diligence.

Anti-diversion clause: require the buyer to use the case for the stated end use. Prohibit re-export to embargoed destinations and require prior notice of any resale to a third party. The clause protects both parties in an export audit.

Documentation pack with first shipment: certificate of origin, commercial invoice, packing list, B/L or AWB, and any product-compliance certificates (IP rating, ATA 300 if specified, MIL-STD-810 method reference). For US-bound shipments, the buyer handles ITAR/EAR licensing on the contents.

Payment and trade terms: T/T 30% deposit + 70% before shipment, EXW Shenzhen / FOB Shenzhen / FOB Ningbo only. No DDP quotation and no overseas warehouse, so duty, import clearance, and inland distribution sit with the buyer.

MOQ and lead time: 100 units per model per foam design with CNC-cut interiors; 50-100 units for standard interiors. Custom colour via PP/ABS masterbatch adds 300-500 units MOQ. Production lead time 30-45 days at 100+ MOQ — case moulding 15-20 days, foam CNC 7-10 days, assembly and QC 5-8 days. Custom foam sample 7-15 days with two revision rounds.

Pricing (2026, FOB Shenzhen/Ningbo, 100+ MOQ): IP67 case with CNC-cut layered foam designed for an AR15-class rifle: USD 28-55/unit. IP68 with stainless hardware and CNC foam: USD 45-85/unit. Wheeled multi-rifle variants: USD 12-25/unit adder. Comparable Pelican Mobile Armory cases retail at USD 350-550 in US channels — direct factory B2B is typically 40-60% below the name-brand price.

Distributor workflow: brief the order contract end-use language with counsel, set up the import licence pathway for any US-origin contents, model the landed cost using the FOA case (freight + duty + MPF/HMF + inland), and build the resale margin on the contractual warranty and SLA rather than on a marketing lifetime warranty.

B2B recommendation: for a distributor serving the US LE and training market, the China factory case is a 40-60% saving on a comparable name-brand case, with a 5-10 year contractual warranty that is materially equivalent to the premium lifetime warranty for any programme under 10 years. Pair the case with a written SLA, a defined end-use statement, and a clear ITAR/EAR division of responsibility.
