    I have a friend that has a SBE 1 giving him cycle issues recently. I own 3of them and dont have issues if I mount he gun corectly. 2 of mine have Sure Cycles.

    Buddies gun has a Sure Cycle system and he has owned it for years with very little instance. He maintains and cleans it regularly. I tore down the bolt assembly and cleaned the receiver. A small amount of FP 10 on the rails and bolt rotation index the gun was good for one Hunt. 4 Shots no issues. The next hunt same issues. Thinking possible mag tube / Mag spring, dirty or weak spring.

    Any additional thoughts?

    That's about all it could be.

    I'd check the recoil spring/tube. Maybe order a new spring from Wolff, they only cost about $12 and will solve many cycling issues.

    If you think its mag spring pull out and stretch and check tube for crud and light lube with clp. Also scrub chamber good with bore brush hooked in drill w solvent. Buttstock recoil spring can also be stretched and reinstalled. Should give you and idea if these were issues. If works time to replace those items for permanent fix.

    The bolt rails of SBE's are their Achilles Heel. Jeff @SureCycle once suggested keeping marine grade grease on them. Of course, this necessitates regular cleaning of the rails as grease is a great dust attractant.

    I will throw this one into the mix since it is an SBE I. I had cycling issues with mine and replaced the extractor claw and the problem went away.

    Some smart guys on here!

    New mag spring...

    New recoil spring...

    And I agree 100% on the extractor, they can lose their edge over time, get a new extractor spring at the same time...

    I just replaced recoil and mag spring in a friends SBE2 that after 4 years became a single shot even after being sent back to benelli 2 times. Wolff 25% extra springs in Recoil and Mag fixed it right up. Cycles perfectly now.

    Have your buddy call the people at Sure Cycle to replace the springs both the mag tube and the recoil spring.
    If they charge to anything it won't be much.
    They just replaced both of my springs for free and it fixed my double feed and failure to feed problem. Make sure he has the gun appart so he can tell the person at S.S. if he has the regular recoil spring or the heavy reciol spring. He can tell them which one he has by the length of the spring tube. On The sure cycles the mag springs housing tube is a little longer than the regular strength spring, unlike the Wolf springs.
    Best of luck to you.

    I have used grease on my rails and also where the bolt strikes the chamber mouth and rotates. If it is stove piping it may need a new ejector. My ejector housing was slipping where it was held in place with set screws 98 SBE1. They changed/improved the ejector in later SBE1s.
