| Ive been looking at ak parts kits, and Ive noticed some say are for a milled lower. Why is that? What part(?) is for a milled lower only that I couldn't use on a stamped lower? |
|
With some work a milled kit can be used with a stamped receiver from what I understand. Any buttstock that comes with a milled kit will not work with a stamped reciever, and milled kits will be absent a trunnion. The handguards will also most likely need a little fitting because they are generally slightly different ETA: There is no such thing as a lower or upper in the AK world.
|
| There is also a difference with some barrels and the different receivers. A lot of surplus milled AK kits have barrel parts that will only fit on the heavy barrel that was used in the older milled AKs. Most of the barrels commonly available for "AK-47's" are actually for AKMs and won't work on these kits. |
| I have a milled kit that was assembled on a stamped receiver. The trunnion holds the barrel on a stamped gun, so it doesn't matter. In my case, it was a Global Trades [Arsenal USA] build using a 100% #'s matching Polish milled kit, & a Hungarian SA 85M receiver. Obviously, they had to come up with both trunnions, as the milled kit didn't have any, but the stamped gun needed them. The gun was called a SSR 85C, & should not be confused with the later built ISD guns. It has the beautiful blonde wood. One of my favorite AK's. GARY |

GARY I'm talking about the barrel parts.. gas block, FSB, and maybe the RSB.. It's an issue with the no barrel kits. Like the 45 degree gas block from an early milled AK won't fit on an AKM profile barrel (barrel is too thin). It's an issue because most of the barrels on the market these days are AKM profile. So if he picks up a barrelless Bulgarian milled kit, he can't just grab one of the Romanian barrels out there, or most of the US made barrels because they are AKM profile. |

I see, I never bought a kit w/o a barrel. Doesn't Green Mountain make AK 47 profile barrels? Wouldn't this work?

This is more complicated then I thought lol It's not that bad. For the most part, a lot of the receiver parts are interchangeable, and only vary cosmetically. Top covers, selectors, recoil springs, trigger groups, bolts, carriers, and trigger guards for example, can be used for either type. Usually, when AK "milled type" or AKM type is used to identify a part, it's referring to barrel components. On a whole, milled AK barrels are heavier profile, and have larger component journals. The rear sight block, gas block, handguard retainer, and front sight block are all different. The gas tube is vented on a milled gun, whereas the gas block is vented on an AKM. The tube is the same size. Muzzle devices and sight posts will carry over. As far as furniture goes, butt stocks aren't compatible, but the upper hand guard is. The lower handguards will interchange with minimal effort. The "tang" that inserts into the from of the receiver is smaller on a milled gun, so it'll be loose on an AKM, and and AKM handguard will need to be trimmed as well as inletted for the heavier profile barrel. I just got done building this. It's basically a milled kit (albeit sourced piece by piece, and includes both Polish and Bulgarian bits) with AKM front and rear trunnions and a Yugo barrel. 
The Yugo barrel is similar to a milled type, but the spacings between journals is different, and some work is needed to get things right. Things get really complicated when it comes to the "hybrid" barrel setups on the newer Bulgarian guns that use AK74 components. |

I should also say that it really shouldn't be hard to find a barrel for the kit you are looking at. The 1960 Polish barrel is for milled receivers only (I think). If you are wanting to build a milled kit on a stamped receiver then you would just use an AKM barrel. You shouldn't have any issues with the barrel. Quoted:

This is more complicated then I thought lol Negative. A milled kit's barrel components will be too large for an AKM barrel. I'm assuming you want to use everything that comes with the milled kit. The cheapest solution is a Yugo take-off barrel from the Centerfire Systems lottery. Weld up hand guard retainer and barrel pin slots, move hand guard retainer back about an inch, and you're good to go. The only similarity between a milled and stamped type barrel is the journal at the chamber. They're both 23mm. An AKM barrel will fit into a milled receiver, and an AK barrel will fit into a stamped receiver's trunnion. All of the other journals are different. The distance between component journals (front sight, gas, block, retainer, rear sight) is also the same, but their respective diameters are not. Of course, the threaded muzzles are also the same. Tanner- What do you want to build? I've done a million combinations in my head, and can try to steer you in a direction if you want help. |

I just wanted to build a cheap battlefield pick up with all wood furniture. 2005 is over. Kits aren't cheap. Barrels aren't cheap. Tooling isn't cheap (really it wasn't cheap then, but cheap kits with barrels meant you could build enough rifles to amortize the cost of tooling). |
