i have one of the bulgie krink kits from k-var and want to get a krink built. i have some questions i'd like to get cleared up here so i don't ask the builder any questions that might scare him off. 1. can or should these be built on milled ak47 receivers or are stamped ones better? 2. what style of receiver is best, no tang, two tang, wu tang, or one tang? 3. who makes the best krinkov receivers? 4. i understand the stock must be fixed (at least until/if the awb sunsets). i have heard of pinning and welding. i understand welding is permanent and can't be undone except by an expert gunsmith but that pinning, while considered permanent, can be reversed by the owner. true? if so, is this an easy process and which builders pin the stocks open? 5. for the barrel extension, i've seen fake suppressors that are just tubes welded on and others that make tubes that look like russian suppressors. who makes the russian type? 6. i want to get an sbr permit from the batfe so i don't want the extension permanently welded on. what's the process for this job? do i ask/tell the builder anything specific? 7. do i need to send the entire kit in or can i just get the barrel installed into my receiver? after reading about the fun all you guys have, i've been thinking about taking the plunge and assembling my own firearm... 8. what is the deal with u.s. parts? is there some type of formula? 9. is it legal to use full auto parts in assembling a firearm even if it's in a semi auto receiver? 10. if i use only semi auto parts, once i get the krinkov built should i get rid of the full auto parts? if i keep them will that "constructive possession/intent" thing make me a target for the batfe??? that's all i can think of right now. if you have any other tips or comments i'd be very grateful! thanks guys! |

Lots of questions. I don't know the answers to all of them, but having looked into this myself somewhat I can relay what I've found, and those with more experience can correct me if I'm off a bit- #1 I believe the stamped is fine. MIlled adds considerably more weight. MIght be nice for the 7.62x39 since that's going to recoil somewhat more. #2 For the rear tang, what type of stock is going to be used? If you're sticking with the standard AK stock or the Romanian folding stock, then the stamped version with two is fine. The WUM version that's curved you won't find on a DIY AK receiver and makes other stocks unable to be installed. If you're going with the underfolder, or sidefolders, I wouldn't worry about the tang as those stocks pretty much require enough changes to the receiver so that they use their own attachment method. #3 Ohio Ordinance Works is a name I've seen pop up a lot for builds that people are doing. Global's receiver is a bit thicker, and I wondered if that would be a good idea for a little additional thickness for additional recoil from the smaller package gun, especially if in 7.62x39. I couldn't find any posts here since the change was made, and I didn't read up on them prior to the board change. Someone else with info on these will have to chime in. #4 I think if you talk to the person you're going to have build it you could get more info on what will be required to undo the pinning. Again, it really depends on what type folding stock you're going to be using. #5 Inrange and Ohio Rapid Fire have models on the Russian style extension for sure, and there may be others. #6My suggestion for SBR'ing is to get the rifle done up with an extension first, so that you can at least have something to shoot while the paperwork is in effect. Short version of this process is form has to be filled out, fingerprints, Official signature, $200 tax must be mailed in. Then the waits starts while background and approval comes, which can be 6wks or 6 months. If the builder is doing this from the start he must have this approval before he can build the gun. That's why get the extension first, then apply to SBR it after the approval. The Krinkov barrel is about 8-9 inches. Use that an an extension to make the legal 16 inch length. Don't get a 16 inch barrel that must be cut is my opinion, but that could also be an option that doens't need the extension. An attchment that's silver soldered on can be removed once approval comes. #7 I think a gunsmith building your gun can do as much or as little as you ask him to do. Call one of them and they can probably give you a quote. AKUSA, ORF, INRange, ARS, and others are names I've heard thatdo pretty good work for customers. #8 There must be a combo of 10 US parts installed (Usually the fire control group, stock parts, gas piston, stuff like that) to comply with an ATFE ruling that says that many parts now makes it so it's not a foreign importewd weapon banned from import back in 1989. #9Not sure on this one. AR15 wouldn't be legal. Have to defer.... #10Same as above.... #11 Oh, there isn't a #11....that was a lot, and I hope that this helped somewhat. Again, if someone else has better info, please correct me. |
