CBP 5.56x45mm NATO Rifle and Parts RFI 20154948

Technical & Requirements Clarifications-

1. Are alternates / brand name equals going to be accepted?

a. Yes. Alternate products may be accepted providing that the product meets or exceeds all specifications listed in the SOW for that specific product.

2. In SOW section 4.6.8.c , The semi auto two stage trigger is referenced, but there is a contradiction as it references SOW 4.6.17 which is a select fire trigger, not semi auto. Can you please provide clarification?

a. CBP seeks to utilize the specified trigger(s) from 4.6.16 and 4.6.17 (or equivalents) in both semi and select fire rifles in order to reduce parts inventories.

3. What is the NSN and Quantity?

a. Although many individual parts within the SOW may have associated NSNs, there is no NSN for the rifle(s) being sought. The quantity for each item is indefinite and would be determined by each Delivery Order placed within the lifetime of the contract.

4. If the manufacturer Flares the mag wells for easier magazine insertion and the rest of the receiver is Mil spec will you accept?

a. Yes. The SOW will be updated to reflect that a minimally flared magwell, that does not cause interference with gun locks, storage, or ancillary gear, may be accepted.

5. SOW 4.6.14 – Buffer Spring Requirement Is the mil-spec buffer spring requirement intended to specify dimensional and material compatibility with the U.S. military-standard M4 spring, or is the intent strictly performance-based, allowing alternative materials or geometries so long as performance is met?

a. The intent to specify a mil-spec buffer spring requirement is to specify dimensional and material compatibility with the U.S. military-standard M4 spring and ensure complete programmatic compatibility and interoperability with CBP’s arsenal of M4 rifles from various manufacturers.

6. SOW 4.3.1(b) – Chamber Specification Can the Government provide a 5.56 NATO minimum-spec chamber drawing and the inspection methodology used to validate compliance?

a. Drawing included below.

b. The government will use the following Pacific Tool and Gauge gauges to measure for compliance with the minimum 5.56mm NATO specs.

0. 5.56 NATO Go Gauge W/ Extractor and Ejector clearance cut

0. 5.56 NATO No-Go Gauge W/ Extractor and Ejector clearance cut

0. 5.56 NATO Firing Pin Indent gauge

0. 5.56 NATO Throat erosion gauge

0. 5.56 NATO Function Gauge

0. 55926858 - Firing Pin Hole Gauge, Go and No-Go with Handle

0. 55642341 - Trigger Pin Hole Gauge, Go and No-Go with Handle

7. SOW 4.3.2(d) – 14.5″ Barrel Profile May the 14.5″ barrel profile be government profile or equivalent, provided performance and durability requirements are met?

a. CBP will accept “or equivalent” for the 14.5” barrel provided all the performance and durability requirements of the government profile barrel are met. SOW to be updated.

8. SOW 4.3.4(j) – QD Insert Placement If QD sling inserts are included, must they be located strictly at 3 and 9 o’clock, or will alternative placements such as 10 and 2 o’clock be acceptable?

a. CBP will accept alternative placement of the QD sling inserts. SOW will be updated to reflect the acceptability of alternative points and the inclusion of a requirement for a durable black oxide stainless steel, nitrided ordinary steel, or equivalent steel sleeve for any QD inserts.

9. SOW 4.4.1(d) – T-Markings Is the letter “T” specifically required on T-markings, or are numerical position markings alone acceptable?

a. The “T” is not specifically required. Numerical position markings are acceptable. SOW to be updated.

10. SOW 4.4.6(b) – Extractor/Ejector Spring and Pin Configuration The SOW states:

• “extractor spring and roll pin”

• “ejector spring and solid pin” Was this reversed from the more common configuration of extractor spring + solid pin and ejector spring + roll pin?

a. This was inadvertently reversed in the draft SOW. The SOW will be updated to reflect:

• extractor, spring, and solid pin

• ejector, spring, and roll pin

11. SOW 4.8.4 – Armorer Training Tool Sets The SOW specifies “4 sets of tools per participant” for depot-level armorer training for 25 participants (100 sets per year).

Should the Contractor provide these at no cost to the Government, or will tool sets be a separately priced line item?

1. This was meant to be a total of 4 sets per year for the CBP Depot-Level Armory. The SOW will be updated to reflect that the vendor will be required to provide 4 sets per year of all specialty tools needed for rifle assembly/disassembly and full gauging sets at no additional cost to the government.

12. SOW 4.8.4(g) – “.020” Reference What does the notation “.020” refer to? Is this a tool dimension, tolerance, or another specification?

a. This portion of the SOW should read, “0.020” Thickness Gauge”. The SOW will be updated.

13. SOW 4.6.2(d) – Fire Control Engraving For semiautomatic lower receivers, the SOW requires “safe and semi.” Will CBP accept “safe and fire” as functionally equivalent?

a. CBP will accept “safe” and “fire” as functionally equivalent. The SOW will be updated to reflect.

14. Definition of “Mil-Spec” References Across the SOW Several sections use the term “mil-spec” without referencing a specific military document, TDP revision, or standard.

Can CBP identify which mil-spec sources (e.g., M4A1 TDP, MIL-DTL references, or NSN specifications) apply to key components such as the barrel assembly, BCG, buffer system, and receiver extension?

a. For the purposes of this Statement of Work (SOW), the term MILSPEC refers to the technical, material, and performance standards established by the United States Department of Defense for military equipment, specifically as they apply to the M4-style AR platform rifle and its associated components. CBP defines MILSPEC as adherence to the design, material, manufacturing, and performance standards established by the U.S. military for M4-style AR platform rifles and components, ensuring full compatibility, reliability, and interchangeability with standard-issue military rifles and parts.

· Compliance with Military Specifications:

All parts, assemblies, and complete rifles designated as MILSPEC must be manufactured, constructed, and assembled in accordance with the applicable U.S. military specifications or standards referenced within this SOW (e.g., MIL-DTL-71186B for M4A1 Carbine, MIL-B-11595E for barrel steel).

· Interchangeability and Compatibility:

MILSPEC items must be fully interchangeable with the corresponding components of a Colt brand M4A1 5.56mm Carbine. This includes dimensional, material, and functional compatibility to ensure seamless integration and reliable operation.

· Performance Requirements:

MILSPEC items must meet or exceed the performance requirements outlined in the referenced military standards, including but not limited to durability, reliability, corrosion resistance, and operational effectiveness under specified testing protocols.

· Quality Assurance:

MILSPEC items must be subject to rigorous quality control and assurance processes, and must pass all applicable inspections and testing as described in the SOW and referenced military documents.

· Documentation and Traceability:

MILSPEC compliance must be supported by manufacturer documentation, certifications, and, where applicable, authorized distributor letters.

15. Endurance / Reliability Test Protocols (MRBS/MEBS) Will CBP publish the endurance test protocol used to determine MRBS/MEBS performance, including:

• round count

• lubrication intervals

• ammunition mix

• environmental cycles

• pass/fail criteria?

This information is critical for accurate performance planning.

a. CBP will provide detailed endurance and reliability test protocols within the Statement of Work (SOW) for M4 Rifles and Parts. Section 5 (Performance Standards) of the SOW will describe the standards to be assessed, to include round counts, lubrication intervals, ammunition mix, and pass/fail criteria.

16. Annual Spare Parts Usage or Estimate To support realistic sustainment and pricing, can CBP provide a notional yearly spare-parts usage rate or an estimated annual quantity for common parts (e.g., BCGs, extractors, springs, firing pins)?

a. CBP recognizes the importance of accurate sustainment planning and pricing for spare parts. At this time, CBP does not provide a notional yearly spare-parts usage rate or estimated annual quantities for common parts (such as bolt carrier groups, extractors, springs, or firing pins) within the Statement of Work (SOW).

Potential performers are encouraged to utilize industry-standard sustainment models, historical usage data, and reliability projections based on the specified endurance and reliability testing protocols to develop their proposed spare parts estimates and pricing. Should CBP develop or release notional usage rates or annual quantity estimates during the solicitation process, this information will be provided to all offerors via amendment or clarification to ensure a fair and transparent procurement process.

17. Material Source Approval Will CBP provide an approved materials list (e.g., barrel steel, bolt steel, aluminum alloys), or will equivalent/commercially available materials meeting or exceeding performance requirements be acceptable?

a. Unless the material is specifically identified as a requirement in the SOW, equivalent/commercially available materials that meet or exceed the performance requirements may be accepted.

18. Warranty Start Date Does the warranty period begin at:

• shipment,

• Government receipt, or

• first issuance to an agent?

Clarification will help ensure accurate lifecycle cost projections.

a. Warranty period shall begin for each item upon government receipt.

19. Government Inspection & Acceptance Location Where does CBP intend to perform acceptance inspections. At the contractor facility, a CBP location, or a third-party test site?

Additionally, will the Government specify who is responsible for associated travel or testing costs?

a. The vendor shall bear all costs associated with any pre-solicitation testing, inspections, and evaluations required to ensure compliance with the specifications outlined in this Statement of Work (SOW). This includes, but is not limited to, material testing, dimensional inspections, performance testing, and any other evaluations necessary to demonstrate conformance to standards and contract requirements. The government will conduct all testing associated with solicitation source selection at the CBP Advanced Training Center in Harpers Ferry, WV at no expense to the vendor.

Following contract award, the Government reserves the right to conduct additional testing or inspections at its own expense to verify compliance with contract requirements. Should the vendor's product fail to meet the specified standards during Government testing, the vendor shall be responsible for all costs associated with corrective actions, including re-testing, replacement of defective items, and shipping costs.

The government may conduct acceptance inspections at the contractor facility, a government facility, or third-part test site. The government shall be responsible for the travel costs associated with all government employees.
