We do not have a retail storefront that is open to the public. We do, however, offer custom build classes where customers are invited into our classroom for a full weekend of instruction, that ends with your very own self built custom Rifle Dynamics firearm.

No. Please do not transfer any firearms to our FFL prior to contacting us. Your item will be turned away and you will not be reimbursed for any associated fees.

Please contact us if this is the case. This scenario will be addressed on a person to person basis.

All of our barrels are made from 4150 CrMoV, featuring SAAMI Spec chambers, Button Cut and Nitrided. The current twist rate on our 7.62x39mm barrels is 1:10". They all come standard with an 11 degree crown.

Our 5.45 Quickhatch, due to the shorter barrel and lighter cartridge, features at 1:6.25 twist rate.

While concentricity is not the only factor to accuracy, we off the best in quality control by employing Geometric Dimensioning and Tolerancing (GD&T).

All of our barrels are cut to 1/2x28 RH.

A full gallery of our standard and custom colors can be found here!

Lead times are always subject to change due to parts availability, but we’re currently estimating 6-8 months for all custom builds.

To avoid delays in receiving your completed firearm, please provide your FFL information as soon as possible, ideally when your order is placed to
info@rifledynamics.com

Yes! All our barrels are cut to 1/2x28 TPI, so please make sure the muzzle device matches this thread pitch. If it is a smaller bore muzzle device (ex. 5.56mm), Rifle Dynamics has the capability to bore that muzzle device out to .30 cal if needed.

For more information about sending us your muzzle device, please contact us at info@rifledynamics.com

Any and all changes to the order can be made completely free within the first 24 hours of the order being placed. Any changes beyond this point may incur a fee.

Please note that by adding NFA or custom engravings to your build, your initial deposit will become non-refundable as the receiver will be permanently marked with your NFA information or other engraving.

At this time, we are unable to offer our side folder receiver builds as the current parts available on the market do not meet our standards.

Once we are able to source quality parts for these models we will be happy to offer them again.

Quick Ship firearms offer limited customization depending on the model in exchange for a shorter lead time.
Inventory varies, and will be sold on a first come first serve basis with payment in full required up front.

Lead times are always subject to change due to parts availability, but we’re currently estimating 5-7 Weeks for Quick Ship Firearms.

To avoid delays in receiving your completed firearm, please provide your FFL information as soon as possible, ideally when your order is placed to info@rifledynamics.com

Rifle Dynamics is focusing further into production builds. As a result, we are unable to take on parts kits, imported firearms, or RD Upgrades beyond Arsenal, K-USA and PSA. We recommend our friends over at Mesa Kinetic Research, CW Gunwerks, and M13 Industries for assistance with your parts kit project.

We can perform our front end conversion/upgrade services on the following:

Arsenal made/imported:

SAM7 R/SF/UF, SAM5, SA93, SLR95/101, SLR 104 R/F/FR/CR, SLR105, SLR 106 R/F/FR/CR, SLR 107 R/F/FR/CR, SGL 21, and SGL 31

Kalashnikov USA made:

KP-9, KR-9, KR-103, and KR-103 SFS

Palmetto State Armory made:

GF5 series, AK-100 series, and AK-V models

Absolutely! There are 2 ways to go about this:

1. You can submit a Form 1 to the ATF, receive your approval and tax stamp, engrave the receiver with the necessary NFA markings, and remove 1" from the barrel. From there we are able to take on any further work requested such as our front end conversion.
2. You can send us your rifle (after contacting us first). We will perform the necessary work, including the NFA engraving. We will then send the gun to your specified FFL. Once the FFL receives the firearm, you can submit a Form 4 to the ATF. Once approved, the SBR is yours.

Orders are processed in the order they are received, please be patient as we will get to your order shortly. In the mean time, if you would like to ship your item for an Arsenal/K-USA/PSA Upgrade, below are the Shipping Address and Instructions:

1. Please Include the following items in your package

2. Please remove all optics, white lights, lasers, wooden accessories (if applicable), and mounts prior to shipping.
3. Pack the firearm/accessories securely in a cardboard box with foam, bubble wrap, packing peanuts, and or any appropriate material to protect it from damage. Make sure to cover the muzzle/end of your barrel, charging handle, and any other protruding parts. Any damage claims are the responsibility of the shipper. You will be notified of any damage (if any was incurred) when we receive the package.
4. Use FEDEX or UPS Ground to ship your package. Always request "21+ / Adult Signature Required" and insurance on the package with the carrier in case of loss or damage by the carrier.
