Barrel band questions

[Bigbirdmqt]

What is the difference between a Type 1 and 1A band and is a 2 weld Type 1 band, unmarked, correct for a 4,790, 241 QH Carbine?

QHMC did use unmarked type 1 band at 4.79, swivel was unmarked or Q-TK. 2&3 Weld marks were found. There were 2 variations of type 1 band early was narrow aperture swivel (1/4") and later wide aperture (5/16") yours should be wide.

Ken, What would you expect for the front band and swivel on a 4,635,xxx QHMC with a 10-43 BA barrel? Thanks! - Bob

Type 1A band marked either UI or unmarked. Swivel unmarked or marked QU or Q-TK.

Your range should be unmarked band and swivel or U ,UI band with QU , UQ or Q-TK swivel. According to CCNL 334 Q-TK swivel started at 4.67 but you never know.
