Precision Reflex PRi Delta Auxiliary Rail Forearms Review

First Impressions of Precision Reflex PRi Delta Auxiliary Rail Forearms

The Precision Reflex PRi Delta Auxiliary Rail Forearms are designed to provide a simple, yet effective way to add accessory mounting options to a firearm. Precision Reflex (PRi) is a well-respected name in the AR-15 world, known for producing durable and functional components. This particular forearm rail is a 4-inch section of Picatinny rail designed for easy attachment, enhancing versatility without requiring extensive modifications.

I was on the hunt for a streamlined accessory mounting solution for my AR-15. I needed a way to attach a light and a sling point without adding a bulky free-float handguard. The factory handguards were limiting my options, and I wanted something low-profile and robust.

Upon unboxing, the PRi Delta Auxiliary Rail felt solid and well-made. The black anodized aluminum was smooth and consistent, and the included sling swivel felt equally robust. It was noticeably lightweight, which was a significant plus, as I didn’t want to add unnecessary weight to the front of my rifle.

I considered a few other options, including Magpul’s MOE rail sections and some generic aluminum rail segments from Amazon. I chose the PRi Delta Auxiliary Rail Forearms because of PRi’s reputation for quality and the integrated sling swivel mount. I didn’t want to rely on polymer rails for heavier accessories, and I wanted a sling mounting point that was integrated into the rail itself.

My first impression was positive. The Precision Reflex PRi Delta Auxiliary Rail Forearms seemed like a well-engineered and durable solution. I was excited to get it mounted and see how it performed in the field.

Real-World Testing: Putting Precision Reflex PRi Delta Auxiliary Rail Forearms to the Test

First Use Experience

I tested the Precision Reflex PRi Delta Auxiliary Rail Forearms at my local shooting range. I mounted the rail to my AR-15’s handguard at the 3 o’clock position, then attached a Streamlight ProTac HL-X weapon light. I also utilized the integrated sling swivel with a Magpul MS1 sling.

The performance was excellent. The rail provided a solid mounting platform for the light, with no noticeable wobble or movement during firing. The sling swivel was perfectly positioned for comfortable carry and easy transitions. I tested it during a rainy session, and the rail remained secure, and the anodized finish showed no signs of corrosion or wear.

I was impressed by how easy it was to adapt to the new setup. The low-profile design of the rail didn’t interfere with my grip or shooting stance. The light was easily accessible, and the sling provided excellent support. There were no unexpected issues, and the rail performed exactly as I had hoped.

Extended Use & Reliability

After several months of regular use, the Precision Reflex PRi Delta Auxiliary Rail Forearms have held up remarkably well. There are no signs of loosening or shifting, and the anodized finish has resisted scratches and wear. The sling swivel continues to function smoothly and reliably.

I’ve taken the rifle with the PRi rail on several hunting trips and training sessions. The rail has been exposed to mud, dust, and extreme temperatures, and it has continued to perform flawlessly. The sling swivel, in particular, has proven to be an invaluable addition, providing a secure and comfortable carry option.

Maintenance is simple; I usually wipe down the rail with a cloth after each use, and occasionally apply a light coat of oil to the sling swivel. This is far easier and more effective compared to my previous setup, which involved a separate sling mount attached to the handguard. It outperforms my previous setups regarding stability, durability, and ease of maintenance.

Specifications

• The Precision Reflex PRi Delta Auxiliary Rail features a 4-inch Picatinny rail section. This allows for the attachment of various accessories like lights, lasers, and foregrips.
• It is constructed from T6 hard-coated black anodized aluminum. This provides excellent durability and corrosion resistance while keeping the weight down.
• The rail includes a steel push-button sling swivel with a 1-inch ID loop. This allows for easy attachment of slings and provides a secure and reliable sling mounting point.
• It also features a threaded steel swivel stud. This offers an alternative mounting option for slings and other accessories.

Accessories attached to the rail remain firmly in place, even under heavy recoil and rough handling. The integrated sling swivel allows for comfortable carry and easy transitions between shooting positions.

Its strengths lie in its simplicity, durability, and ease of installation. The only weakness is that, at 4 inches, it might be too short for mounting multiple large accessories. It definitely meets my expectations for a simple, rugged, and reliable accessory mounting solution.

Maintenance is straightforward; simply wipe down the rail with a cloth and occasionally lubricate the sling swivel. Repair, while unlikely to be needed, would likely involve replacing the entire unit, as there are few components that could fail.

Accessories and Customization Options

The PRi Delta Auxiliary Rail Forearms are compatible with any standard Picatinny rail accessories. This includes lights, lasers, foregrips, bipods, and sling mounts. The integrated sling swivel and threaded stud provide additional mounting options for slings and other accessories.
