Ordering Tubes – How It Works


Choose the magazine tube capacity you require.

  • Full Length for increased capacity including a U.S. made follower and Wolff spring upgrade
  • Factory Length to maintain OEM configuration while gaining the benefits Titanium affords (magazine tube only)


Choose your preferred finish option.

  • If ordering additional springs which are nearly always in stock, let us know whether you need them ASAP, or shipped with completed order. The latter option will avoid separate shipping costs.

NOTE: We do not invoice until your product is either in stock, or nearing completion!!

  • When you order, you will provide your contact info, including mailing address and phone number, product preferences, and email address.
  • When your product nears completion, we will reach out to you for payment, confirming your order specifics, and mailing address.
  • All parcels are shipped via USPS Priority Mail.

Please feel free to contact us via email with any questions you may have related to our products. There’s no such thing as a silly question !! If you’re wondering about it, odds are we’ve scratched our noggins related to the same question, and either have an answer, or can steer you towards resources that do.


NOTE: We do not invoice until your product is either in stock, or nearing completion!!

The current ETA’s/lead times for mag-tube orders, while still fluid, is approximately 4-5 weeks.

We only ask for payment of backordered items when they near completion, at which time we will call for payment, which is a better way to do business.

Carriercomp is a crew of two, which often prevents us from being near the phone. This makes email our primary form of contact, in an effort to balance production with contact and support for efficient customer satisfaction.

We cherish hearing from and responding to our customers before, during, and after any transaction consideration.

Your patience and loyalty has enabled us to continue operating under a “lean” business model, without having to wield premium retail pricing in the process. Again, Thank You.

All inquiries are handled via email to prevent spending excessive production time on the phone.

Please note we do not ever receive, ship, store, or in any way handle any customer’s firearm, nor do we EVER offer ANY component that would create, enable, contribute to, or facilitate any aspect of a home built or DIY firearm of any type. We do not offer, or perform any gunsmithing services. We do NOT offer, sell, or manufacture any service or component that contributes to any endeavor to produce or complete an item, or assembly that would require serialized records documentation, declaration, surrender, or destruction attributable to, and in accordance with recent ATF rulings. No exceptions.

Thank you for understanding.
