shane_eld 0 Posted July 30, 2012 Report Share Posted July 30, 2012 i just got my black jack recoil buffer hoping that it would work..i didnt like it..just seemed un-natural for the ak platform..waitin on a wolff extra power recoil spring..hopefully that will cure my trunnion to bolt-carrier contact..

G O B 3,516 Posted July 30, 2012 Report Share Posted July 30, 2012 I run BJ buffers in anything that will tolerate them. Quote Link to post Share on other sites
gunfun 3,931 Posted July 30, 2012 Report Share Posted July 30, 2012 If it works with the buffer, the buffer can't hurt. If it doesn't work with one don't use it. Mechanical design and maintenance is not about natural, it is about functional. a bit of trunion contact is normal for AKs, and not necessarily a problem. Is it hitting hard enough to leave galling or deformation? If so, a buffer and/ or a stiffer spring are a good idea. 1 Quote Link to post Share on other sites

Lone Eagle 839 Posted July 30, 2012 Report Share Posted July 30, 2012 I simply used the end mill at work to open the trunnion slot where the bolt was contacting. Now the carrier hits the trunnion, not the bolt itself. Amazing what a 16th of an inch will do. Picking up an XP spring at the show this weekend if they aren't sold out. Seems Winchester and Yugo are hot loads. No smack with Tula and Wolf on my Arsenal. Quote Link to post Share on other sites
hutchsaiga 93 Posted July 31, 2012 Report Share Posted July 31, 2012 cheap insurance Ahhhhhh false. If you're making serious contact with the trunnion. Why would you want to stick a piece of junk in there to make the contact happen earlier in the rearward movement of the carrier when it is traveling more forcefully?? Either you have an oversized gas port or you need too look into a stronger recoil spring. Fix shit right, a buffer is NEVER the answer. 4 Quote Link to post Share on other sites

shane_eld 0 Posted August 5, 2012 Author Report Share Posted August 5, 2012 wolff spring arrived..great results Quote Link to post Share on other sites
shane_eld 0 Posted August 13, 2012 Author Report Share Posted August 13, 2012 goin back to the buffer still have a bit of contact with wolff extra power spring Quote Link to post Share on other sites
BigChongus 765 Posted August 13, 2012 Report Share Posted August 13, 2012 Trunnion contact is normal. You only need to worry about it if it's excessive (i.e causing rivet and/or receiver damage). Quote Link to post Share on other sites
BigChongus 765 Posted August 13, 2012 Report Share Posted August 13, 2012 Even the 5.45 makes contact Quote Link to post Share on other sites
Matthew Hopkins 1,065 Posted August 14, 2012 Report Share Posted August 14, 2012 (edited) here is my thoughts about buffer, stiffer recoil spring - it's a answer to a problem that doesn't exist. all AK bolt carriers hit the trunnion, all you are doing is throwing your money away on useless products, and making whoever sells them happy. I have a MAADI ARM I bought in 95, and put thousand and thousands of rounds through it, way over 10 K, and there is zero indication that anything is wrong with the rear trunnion or loose rivets etc...

shane_eld 0 Posted August 14, 2012 Author Report Share Posted August 14, 2012 ya i know i just dont wanna beat it to death..trust me i definatly shoot enough to put an experation date on any gun so i try and gear up to make it last Quote Link to post Share on other sites
G O B 3,516 Posted August 14, 2012 Report Share Posted August 14, 2012 Buffers are so cheap and easy to install, there is no real reason not to try one. Some guns do not like them. Some guns only run right with one. If the stacking tolerances in your gun allow the carrier to try jumping the rails, a buffer will stop that nonsense. 1 Quote Link to post Share on other sites
Avtomot 5 Posted November 21, 2012 Report Share Posted November 21, 2012 ya i was wondering too..at least im not the only one that is concerned about it. Quote Link to post Share on other sites
Stansplace 414 Posted November 22, 2012 Report Share Posted November 22, 2012 Buffers have always caused issues in my AK platforms..... But you know what they say about opinions. Quote Link to post Share on other sites
TheDarkHorse 216 Posted November 22, 2012 Report Share Posted November 22, 2012 If the stacking tolerances in your gun allow the carrier to try jumping the rails, a buffer will stop that nonsense. This is the case in my STG2003c. At the rearmost position, the carrier pops up and off the rail on the left side. It usually stops the carrier from returning to battery. A 1/4" buffer would prevent this as the carrier would not reach the end of the rail. Quote Link to post Share on other sites
