H&K 417/MR308A1 Upgrades

Along with the G36 upgrades we have also made an upgrade kit for the HK417. With the Spuhr upgrade kit the HK417 is lighter and more user friendly. The project goals were to lower the weight, add a new forend and of course add the capability to use standard magazines. 

R-200 KH417 Full-Auto / R-200S HK417 Semi-Auto Lower 
Our solution involved redesigning the lower receiver and handguard. We developed two new lower receivers: the select-fire R-200 and the semi-auto R-200S.

Our enhancements: 

1. Uses standard magazines. With the more compact magazines there is a greater selection of accessories such as magpouches available. 

2. Low-profile protected magazine catch. Lessens the risk of accidently dropping the magazine without sacrificing ease of access. 

3. Ambidextrous magazine catch. Same low-profile design on both sides. 

4. Non-rotating hammer and trigger pins. Prevents elongation of pin holes from rotating pins. 

5. Built-in QD sling swivel cups. Allows the use of other sling systems than the original "cheese cutter" style. 

6. Reinforced receiver. The rear of the receiver has been reinforced for greater stability. 

7. Built-in Spuhr interfaces. Both sides of the receiver has been fitted with Spuhr interfaces for future use. Maybe for a brass catcher, cosine indicator, a holder for extra magazine or whatever. 

Spuhr forends
We also developed two lightweight handguards, achieving a 25%-33% weight reduction compared to the original designs: the R-210 for 20" barrels and the R-211 for 16" barrels. These handguards feature Spuhr interfaces on the sides. Picatinny Gen2 rails on the top and bottom. Mounting provisions for an underslung HK GLM, offering both functionality and reduced weight. 

R-210 HK417 Long Forend 11.5"
The R-210 Long Forend is a lightweight, modular alternative to the factory Picatinny forend. It features our proprietary smooth Picatinny rails on the top and bottom, ensuring enhanced functionality and ease of use. 

R-211 HK417 Short Forend 9.5"
The R-211 Short Forend is, like the R-210 Long Forend, a lightweight modular alternative to the factory Picatinny forend. As with the R-22 G36 Forend, the R-211 also has a smooth Picatinny rail designed for attaching an HK GLM.
