The nut is threaded and staked to the gas piston housing to prevent it from rotating out of the gas cylinder. Physically check the gas piston nut to make sure it's tight. The design of these nuts does not include the recessed areas specific for staking and holding the nut in place that was mandatory on carbines made to Ordnance specifications during and after WWII.
Historically the stake marks as applied on the gas piston nuts used by the modern day Inland Mfg and those used by Auto-Ordnance have been insufficient to secure the nut in place. Check that the nut is tight before you fire the carbine and periodically thereafter to make sure it stays in place.
Note the mold mark along the top of the barrel between the gas piston housing and receiver. Also the two silver spots on top of the barrel above the chamber.
The barrels are manufactured by casting an outer piece that extends from the gas piston cylinder rearward. It includes the threads for mounting the barrel to the receiver.
The actual barrel with the rifled bore is inserted into this outer piece and sits flush with it's sleeve on the breech end. The barrel is held within the sleeve by what appears to be silver solder. Variations of this method of barrel manufacture have been used by other earlier commercial carbine manufacturers.
Winchester and Inland used a variation of this method when making the barrels for their first carbine prototypes. The Bolt Group Inland's bolts and firing pins are machined from forged steel. Their extractors are cast then hard chromed. Inland has chosen to use round bolts on their carbines. They offer the flat bolt version on their online store as an optional replacement. The only difference between the two is the flat bolt requires extra machining to remove part of the rounded top of the bolt to produce a slightly lighter weight bolt.
Both designs are equal in strength when hardened properly. Although almost imperceptible the bolts used by Inland Mfg and Auto-Ordnance are not made to military specifications. Their bolts are slightly longer, the left locking lugs are slightly shorter, the right locking lugs are machined different and the hole for the extractors is slightly smaller.
Keep in mind these carbines are replicas of the carbines manufactured for Ordnance during WWII and though not made to military specifications the various parts are made to specifications that enable them to work with one another. The tolerances used to manufacture these parts are not as stringent as those used by the companies contracted to manufacture carbines and parts for Ordnance during WWII.
This sometimes allows interchangeability with their GI counterparts, sometimes not. Be aware that should you decide to replace the bolt on an Inland Mfg carbine with a surplus GI bolt or any bolt other than those made for Inland or Auto-Ordnance you should check the head space of the bolt with the carbine you plan on using it with before you fire the weapon. The difference in bolt length may make the replacement bolt unsafe to use in the Inland Mfg carbine. Inland initially used cast extractors parkerized to match the finish of the bolt and carbine.
The extractors had a tendency to break. For a short time Inland replaced the original extractors with extractors machined from forged steel to military specifications.
These were replaced with cast extractors that have been hard chromed as have been used by Auto-Ordnance for years. Manufactured and registered by Broadhead Armory.
