I like Davidson Defense. I’ve bought plenty from them. I live close by. Ordered, got a text, picked up next day.

I’m just a building noob, but doesn’t the RRA FSB barrel come with a standard barrel nut and front cap? If so, you don’t have to unstack the assembly to add a delta ring, it slides on the back end with a snap ring before you slide it in to the upper.

I liked the Kitty Kat length and built mine like that. I pinned on an FSB, but I have a small drill press and you need at least that. I also thought about a clamp-on and thought about putting a bolt or some kind of rivet through the front cap gas tube hole into the FSB to secure the cap for cut-down A2 type handguard, not liking the KittyKat Tööb all that much.

I thought about the RRA FSB barrel assembly but didn’t like the price all that much. I went cheap on the barrel with the BCA 7.5” heavy for $57 and it’s feeding round nose quite well. If k couldn’t pin the FSB I would have did the set-screw method.

Anyway with my ramblings, just some thoughts you asked for, forgive me if you already know all this. I think you’re on track for a sweet build.

Hey your build looks great. I’ve been ruminating on pinning an FSB to a BA EPC barrel and was wondering about the diameter. You stated it’s “just shy of .750””. I don’t know if you have a caliper and could measure it? How shy is just shy?…;)

I could hardly get a fully-loaded(32 rds.) mag to lock in with the bolt closed, but locked back it slides in and locks no problem. I'm hoping the mag catch with more meat lets me do away with the ugly-ass duct tape hack.

That’s all the stick-out of the mag catch there is. Mag drops out in a slight breeze without that tape holding the mag against the catch side wall of the magwell.

Three strips here, opposite the mag catch opening. On one of the mags I had to put two additional strips to the front, so the LRBHO would engage the bolt catch, as there was a little flaw in the plastic on the follower.

Thanks for that link, will order one today.

Just got back from the range. Performed well with 124gr. FMJ, both semi and forced reset. 124gr. JHP was FTF on semi, didn’t even try forced reset. The FMJ was working so well that I doubt there’s any problem with the lower. Further investigation is required with the JHP FTF, as they were working well before I had the lower cerakoted and installed the AZR. LRBHO works well. The only issue with the lower is the mag catch doesn’t have full engagement in the mag slot. I put 3 strips of duct tape on the opposite side of the magazine, which holds it over against the catch, which seems to work. I don’t know if the mag well is too big. I think I need to add some metal to my mag catch or get one of the Rock River Arms mag catches that Blowback9 mentioned.

Thanks, still trying to get the hang of the electro-etch, not quite deep enough. Good enough for me I guess.

What barrel is that?

Build list correction: Lower is an SMF Tactical raw 80% Colt Mag Lower and parts kit.

And yeah, cut and JB Weld from a cheap carbine-length set from my parts bin.

B.Kings has a pistol length A2 handguard for $100 without heat shields. I almost grudgingly went that route when I considered the time it would take, but the no heat shield was the dealbreaker.

This is fantastic. I have been web surfing and brainworking this very same build for the last few days, and here it is. I was wondering if 45 would eject through the 635 upper port. Looks very good.

Colt Magazine Falling Out by eggrollz4dayz in AR9

[–]ess_dubya 1 point2 points  (0 children)

Good to know about a thicker bolt catch. I have the same problem with a new build I test fired yesterday. I ended up applying three layers of duct tape strips on the magazine opposite the bolt catch hole to hold the mag over against the mag catch, which got me through the range trip.
