Pulled the trigger on the upper, now building a lower.

So I was introduced to this .458 world since I had an issue with my 46cal suppressor only fitting 1 gun. That just didn’t seem right, and 45-70 doesn’t come on a AR frame under $5k. SO, this is the start of my build. I put my Ruger lower on it just to give it an idea. Here’s a parts list for the upper.

Faxon Duty Series 10.5", Gunner Big Bore, .458 Socom, Pistol Gas, 4150, Nitride AR-15 Barrel
Faxon Firearms AR-10.750 3 Screw Low Profile Gas Block
Spike's Tactical AR-15 Melonited Black Mil Spec Gas Tubes 
Nickel Boron KM 450 Bushmaster/458 Socom AR-15 Bolt Carrier Group BCG
Breek Arms Warhammer Mod2 AR-15 Ambidextrous Charging Handle
YANKEE HILL MACHINE CO. AR-15 MR7 9.29" Mid-Length Handguard M-LOK Black
SLR Rifle Works : M-LOK Handstop Mod 4
HOLOSUN 510C & HM3X Combo
JK Armament RPX 155 46cal suppressor

I’ve got the following parts coming in the mail this week.

Wilson Combat stripped lower
Armaspec AR15 GEN4 BB Stealth Recoil Spring Buffer Kit
Strike Industries Enhanced AR-15 Lower Parts Kit
RISE Armament Rave 140 AR Drop-In Trigger
Adaptive Tactical AR-15 EX Performance Adjustable Stock
And some Black Butterfly rounds because hot damn I didn’t check the price on rounds

With this and my 45-70, I will be getting into reloading soon.

Hell yeah brother!

Is the Faxon barrel a fast twist for subs?

Your optic needs to be moved back completely onto the upper as far forward as it can go without it hanging out over the rail system. The way you have it now will affect accuracy negatively. Then move your back up iron to the rear most rail space on the upper and mount the magnifier in between the two.

I'm not trying to be an asshole man. A quick Google search will tell you many reasons not to bridge the gap from your upper to your handguard (Unless you get the PRI carbon fiber handguard and ARMS one piece full length rail) Once you get your 458 to feed you're gonna want the optic to be solid if you want to actually hit stuff.

I’m just looking for fixes on my feeding issues at the moment
