I am trying to put together a OAL 16" 22LR barrel assembly in the aesthetic of an XM177E2.

Below is a list of the parts I've come up with:

1. Borebuddy 12" 22LR .625 profile barrel: https://borebuddy.com/product/borebuddy-apogee-22lr-barrel/
2. Luth-AR A1 FSB: https://luth-ar.com/product/front-sight-base-625/
3. BKF AR15 Barrel Nut: https://bkingsfirearms.com/shop/single-products/ar15-barrel-nut/
4. LUTH-AR A1 slip ring: https://luth-ar.com/product/a1-slip-ring-pack/
5. 5.5" XM-style faux moderator: https://www.tntesales.com/xm-177-gau-5-5-5-flash-hider-phosphate/
6. LUTH-AR Handguard Cap (Round) .625: https://luth-ar.com/product/handguard-cap-round-625/

Am I missing anything that would be included in a typical complete barrel assembly? I've searched high and low for a 22LR FSB barrel that would work for an XM177E2 style rifle and it seems the only option is to make one up. I would be sending these parts to be installed/pinned & welded by a gunsmith. If anyone has any recommendations either for the parts I've chosen, anything I've missed or a smith who could assemble this for me, I would greatly appreciate it! For smiths it seems like ADCO would do everything I need.

I got my first shotgun in a Wal-Mart parking lot in South Carolina 13 years ago. It was a pre-1968 M500A with one action arm and no serial #. Unfortunately I ended up having to pawn it before I moved. I may have less hair now, but I certainly have more shotgun
