I am helping my buddy's GF build one for him. It's chambered in 7.62x39 though. I only had a few minutes to mess with it. It couldn't light the primers on the shitty cheap steel surplus ammo,,, but this is common on 7.62x39 ARs. I have some BearX extended firing pins due in yesterday now today, so hopefully that will fix it.
As far as the side charger? first time I messed with it (UNLOADED!! ) in the basement, the knob slammed back and pinched the side of my hand in the upper. Little bleeding but no big deal,,, reason I mention is, I am a skinny guy, I couldn't imagine chambering with fat hands and sausage links for fingers. Overall quality is meh,,, and while I have some boutique safe queen ARs, I am fine with a PSA AR for farm duty,,, so I'm not entirely snobby.

 

I've been happy with the Vortex Viper HS LR 4-16 x44mm (older model by now I'm guessing) on my Savage 10T.

 

The 10.5” barrel works with this rail, I’ll probably order another identical rail since I have both 10.5” 556 and 300BLK barrels, I’ll just get a caliber band to wrap the handguard to denote caliber difference.
There’s a very slight clearance issue when the can threads on but all I need to do is hit it with sandpaper or a polishing wheel.

 

I might have a hook up on the Viper HST 4-16x44 will know by the weekend

 

Looks nice! I went with "color coding" my 300blk upper vs 556. FDE=300BLK, black is 556. As for mags I found some labeled rubber bands for them. Works nice for keeping supersonic and subsonic loaded and knowing which is which lol.

 

Thanks! I considered doing the color code thing but my rifles tend to get the krylon treatment so it would get hidden. I plan on using metal mags with “300” spray painted on them to keep the mags separate of my Pmags and lancers, I think that and 1 or 2 of the caliber bands on the rifle should alert someone that’s not me that the caliber is different.

 

So my ballistic advantage 556 barrel isn’t dimpled, a quick google says that the nitride finish used is extremely difficult to drill through, I have access to a drill press but would need to get a dimple alignment tool, should I dimple for the Aero low profile gas block or take it to a smith to get a pinned block installed?

 

Interesting. When I was a child we lived in Florida right on the Indian river you could see the assembly building. I lived there during the lunar missions. Our neighbor across the street worked on the legs of the lunar module

 

My Grandfather was an Aerospace Engineer and worked for Grumman Aerospace in Bethpage/Long Island NY but was at the KSC for weeks/months at a time. We lived in Cape Canaveral out by the port till 78 then parents moved to Tampa. My Grandfather who worked with Thomas Kelly on the Apollo lunar module was transferred over to the Shuttle program to help design the tail and wing sections in conjunction with Rockwell who had the contract in 1970/71 I think it was. I have a lot of memories running around KSC and watching up close rocket launches from the grandstands outside the VAB and launch control building.

 

We were there late 60’s to ‘74 so you and I were there at the same time. Funny and we are close to each other here also.

 

Here is a loaded question. I have been looking for something different, more compact. Use is closer range varying from home defense to under 100 yards. I’m trying to decide which is most bennificial each has its plus and minus. Either a 8” Barrell pcc or a AR 556 pistol?

 

Cz scorpion evo 3 with Innovative Arms integral suppressor.... Just because I want it for mine....

 

The eco 3 is one of the candidates I have been looking at, no can though

 

Next build is either .300blk 7.5 suppressed or a 9mm 7” barrel suppressed. Specifically for home defense.

I just built a 5.56 pistol 7.5” with just a flash can and it throws like two foot fireballs lol

 

Right now Im trying to imagine a 7.5” barrel 5.56 going off in a hallway. Goodbye ears lol

 

Got the new “pistol” build semi-finished today, I still need to install forward assist and the ejection port door as well as decide what I’m going to do about the gas block (and then install CH and BCG), but I’m pretty happy with how it looks.
I’m not sure how the TLR-1 will do being mounted even/forward of the muzzle device though, that may end up moving.

I think it will be a good “mid tier” pistol, Aero stripped upper, BA barrel, Aero gas block, Griffin muzzle device and sights, Larue MBT straight bow trigger, MOE k2 grip, joe bob outfitters LPK, and PSA lower, the BCG is from “Right to bear” and is a rebrand WMD, I haven’t heard of them but it’s supposed to be true mil-spec and nickel boron coated so we’ll see how it does.

 

It’s miserable, this is my buddy, a former 11B who was bragging that he didn’t need ear plugs because they shot 50’s without ear pro at training, he had decreased hearing ability for about 24 hours after this.
