GHK 10.5 Inch Steel Outer Barrel - for M4 GBB
- Suitable for GHK M4 GBB series
Order came incredibly fast for something that was shipped from Hong Kong! I was genuinely surprised! For the outer barrel itself, it's GHK, so nothing else to it! It's a great and reliable outer barrel for any CQCR rifles! Definitely recommend from buying this website and their products!
