HK Piston 3-Ring Replacement Set

HKP Gas Piston Ring Replacement Combo Set- 3 Rings

The gas rings are prone to periodic breakage and wear and tear and require them to be replaced periodically. These are some of the most common breakage parts we see that need to be replaced on these weapons systems. Each set includes 3 individual rings (enough to replace all the rings on a gas piston). When replacing the gas piston rings they should be replaced together as a new assembly. Per HK directly you should not reuse old rings once they have been removed from the gas piston assembly.

Compatible With:

• HK MR556
• HK416
• G36E
• G36K
• G36C
• SL8-1
• SL8-6
• All HK 416 & G36 variants that use a gas piston with rings
