【Material & Manufacturing Method】
> Material
Polyamide 12 (PA12/nylon) is a plastic material that is a very sturdy polymer used in automobile industry.
> Manufacturing method
DCI GUNS parts are made in a 3d printing machine using the SLS technology (Selective Laser Sintering). The SLS printing method using PA12 results in very resistant parts and nice finish. The parts are very light weight and do not interfere with the blowback recoil of GBB guns.
【Metal Inserts】 (except for HiCapa5.1 or 4.3 and others)
This accessory is using metal inserts on the screw thread parts on both sides (RMR side / slide side) for a very easy setting and durable screw threads.

Durability test and shooting test have been done during the development period of this accessory mount.
※No toygun or RMR dot sight included

Rock-Solid Mount for the Tokyo Marui M45A1
The DCI GUNS RMR Dot Sight Mount V2.0 is an excellent upgrade for anyone running a Tokyo Marui M45A1 GBB. From the moment I installed it, the quality and attention to detail were obvious.
The use of PA12 nylon through SLS 3D printing provides a perfect balance of durability and lightweight construction. It doesn’t interfere with the blowback function at all, which is critical for performance and reliability in a gas blowback setup.
The inclusion of metal inserts on both the RMR and slide sides is a major advantage. The threads are strong and make installation both easy and secure. No stripped threads, no wobble—just a clean, tight fit.
Functionally, the mount holds zero without any issues. I’ve tested it extensively, and it stays locked in place even after heavy shooting sessions. It’s clear that this part went through proper durability and shooting tests during development.
If you're serious about upgrading your M45A1 with an RMR, this is one of the best options on the market. Clean finish, rock-solid performance, and intelligent design choices throughout. Highly recommended.
