GotTheTshirt Posted August 24, 2022 Report Share Posted August 24, 2022 Searched the threads and didn't find anything, so, has anyone used the KAK Heavy Short Buffer in the 308ARs? If so, what are your thoughts / experiences? LR-308 CARBINE HEAVY BUFFER (kakindustry.com) Quote Link to comment Share on other sites More sharing options...
RacerX Posted August 24, 2022 Report Share Posted August 24, 2022 (edited) I used them in my last 2 (did 2 at the same time) builds. They definitely work, but they are actually 5.1 ounces, not 5.3 as advertised. The one from heavybuffers is 5.5 ounces. I wonder how much difference there is with .4 ounces. I wish I would have had both to compare at the time. Edited August 24, 2022 by RacerX Quote Link to comment Share on other sites More sharing options...
GotTheTshirt Posted August 24, 2022 Author Report Share Posted August 24, 2022 Thank you. I currently have a 3.8 oz with SprinCo Orange and was considering if the investment would be worth it. Quote Link to comment Share on other sites More sharing options...
blue109 Posted August 24, 2022 Report Share Posted August 24, 2022 (edited) I have one. To be honest, the gun behaves the same with a KAK+Springco orange as it does with a standard DPMS buffer and spring. I was swapping them back and forth and I honestly didn't notice a difference. Brass pretty much ejected to the same spot. Recoil impulse felt the same. I think I ended up keeping the KAK/orange in the gun just because it's "better" and I already paid for it, but it wasn't a necessary upgrade at all. If your gun is running, I'd say don't waste the money. If your gun ISNT running, I'd say the buffer probably isn't the fix you are looking for. This was on a 16" carbine with a nasty comp on it. YMMV. Edited August 24, 2022 by blue109 Quote Link to comment Share on other sites More sharing options...

edgecrusher Posted August 24, 2022 Report Share Posted August 24, 2022 Your 3.8 oz buffer is too light for a .308. It should be a minimum of 5.3. It may be considered heavy for an AR 15 but on a 308AR it’s standard weight. A heavy buffer for .308 is typically 6.5/8/10 oz. Quote Link to comment Share on other sites More sharing options...

LR-308 CARBINE HEAVY BUFFER (kakindustry.com) Lots of comments on that KAK buffer here, and it's a common recommendation for Carbine extensions that are 7.000" internal depth, and coupled with the Sprinco Orange spring. It's good to go. Quote Link to comment Share on other sites More sharing options...
GotTheTshirt Posted August 29, 2022 Author Report Share Posted August 29, 2022 Well, after some research, decided to try the Spikes as it is listed a little heavier. Will report how it goes... Quote Link to comment Share on other sites More sharing options...
GotTheTshirt Posted September 3, 2022 Author Report Share Posted September 3, 2022 Went to the range today. The PA-10, Sprinco Orange, and Spikes Tactical ST-X1 make for a smooth shooting rifle. Thanks all for the feedback. Quote Link to comment Share on other sites More sharing options...
