Actually the guy selling the titanium muzzle brake on eBay got bought out by Anarchy Outdoors, so same 35 hole brake just better place to sell as eBay is still Anti Gun.
I have my first one from eBay several years ago, then next 4 or 5 from Anarchy Outdoors, all identical except you can get it in black now. |

Started my PSA KS-47 build. Still have a lot of parts to buy for the upper but waiting to sell some stuff first. Lower is nearly complete though. I want to lighten up the mag catch. Test for reliability with a bobbed hammer, and buy a Vseven safety. I’ll do a detailed parts list with weights once it’s finished but here it is as of now.
The factory upper weights 4 and a half pounds!

What's the difference between the PSA KS-47 and an AR15 in 7.62x39?
I am rebuilding my 7.62x39 for the third time, shoots pretty good considering the cheap steel ammo. |

I'm putting a rca adjustable gas key on it so I'm sure it'll be great. It's the same materials, 7075 aluminum just less of it! Thing feels like a toy... The bolt sleeve where the gas rings scrape seems looser than the jp (I'm using a jp precision ground gas ring) but it's not so loose that it won't work. Probably... If it is I'll just order some ion bonded gas rings. I really like it and it's a great value to boot! Especially compared to jp or whiskey aluminum carriers.

And we have a new champ. 5 grams for the Daniel defense port door/dust cover. I put 2 on the scale together and it came to 10 grams. For any of you new guys putting 2 of an item on a lower precision scale can give you a better idea of the exact weight. For example if I put 1 of my Titanium bolt catch detents on the scale and it says one gram but I put 2 of them on the scale together and it says 3 grams I know I'm closer to 1.5 grams than 1 gram. Half a gram is all the precision I need in a scale! Anybody want a hk416 polymer door or this spare dd door? Just pay me shipping.

Well I guess the hera is still the champ since it comes with a plastic rod/pin. Unfortunately the hera won't work with the polymer blackthorne upper. Nothing with an adjustable detent will.

Just looking at the New Frontier website and see that they now have a 'carbon fiber' lower much like Tegra, looking at the pictures it's almost the same except has their imprint on the side instead. Wonder if it is just a branded version of the Tegra. Anyone else notice this?

My KS47 is nearing completion, one of the things that was bugging me was the over size chunk of steel for a mag catch so I pulled that out today and cut the wings off of it. .34oz lighter. As it sits right now the rifle with red dot weighs 5lbs 8.3oz. The bcg is still 11oz and I hope to get that on the mill next week to bring it down around 9.7-10oz.
On a side note the sharps bros 13.7” handguard weighs what the manufacture claims. 9.1 for the handguard 1.3 for the barrel nut. |

Milled the bolt carrier today. Got the BCG down to 9.4oz. Super happy about that. This project is like 99.5% done now. Trying to somehow justify a V Seven safety selector. Going to the range Monday to test functionality and decide on what size gas block insert to run. After that is done i can lock down the gas block and torque the flash hider down and its all done.
Under 7lbs with a full 30 round mag of steel cased 122grain 7.62x39

Close but no Cigar. With the titanium pistol grip I am @ 2.48 pounds.
Still I think we may be the only 2 people under 3 pounds. Do you realize how much your 556 weighs compared to the heavy Ruger 10-22 takedown? Firepower comparison 22LR vs. 556 10 rounds vs 30 or 40 rounds |

That handguard is heavy, try a magnesium one from dark hour or v7. Maybe a triangle charging handle? A hogue 15 degree grip is pretty light too, and cheap! Of course the lightest grips are 3d printed titanium. Iron City bolt carriers (FA) and jp (SA) are the lightest steel bolt carriers you can get, you can always try a ds arms aluminum carrier.

Throw an adjustable carrier key on the carrier, then take the weights out of the buffer. Most of us use either a TACCOM polymer buffer @ 1 ounce or the weight free buffer @ 1 ounce.
Get rid of the heavy pistol grip and buy a Hogue 15 degree grip, @ 1.5 ounces only $20. A milspec trigger group is HEAVY, the lightest steel is the Hiperfire EDT, saving between 1 and 1.5 ounces. A lot of us use the New Frontier polymer trigger group |

Bah!!! Humbug!!! I lied about my weights. Here are the pics on the scale. I was weighing myself and then myself and the rifles on the bathroom scale and I guess my brain wasn't up for doing math that morning 🙄 I'm ashamed of myself 😂 that's grams btw, 2047 g for the 308, 1412 for the 556.

There’s weight that can be cut by turning the barrel down to .500 in front of the chamber.
