MERKEL BOLT HEAD FOR STANDARD RX HELIX
The Helix has three calibre groups - Mini, Standard and Magnum. When changing from one calibre group to another, the bolt head must also be changed.
This is the standard size bolt head which is required for calibres: .243 Win., 6.5x55 SE, .270 Win., 7x64, .308 Win., .30-06 Spfd., 8x57IS, 9.3x62.
This also provides an additional safety as when the bolt head is removed the rifle is protected against unauthorised use.
