HKP HK Piston Ring Replacement Set - 3 Ring Combo

HK MR556, HK416 & G36, SL8 Gas Piston Ring Replacement Combo Set - 3 Rings

This is a high wear common repair & replacement item. The gas rings are prone to periodic breakage & wear, tear and require them to be replaced periodically. These are the one of the most common breakage parts we see that needs to be replaced on these weapons systems. A great spare to have on hand for all HK G36/SL8 & 416/MR556 weapon systems. Made in the USA from the same material, heat treat, specs and prints.

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, HK 416A5
• G36E, G36K, G36C all variants
• SL8-1, SL8-6 all SL8 models
• Omega G36 style offerings
• All HK 416 & G36 variants that use a gas piston with rings
