I wonder if you can cut a little bit of delrin or even the top part of the stock buffer and epoxy it on the head of the angry gun buffer? Maybe that will ease the metal to metal impact.

Please keep us informed if anyone is able to find a way to have this run in their gun without it overly wearing down the internals. Im afraid to try it out!

I think I just wasted $40 on this kit. Brand new and never used since I found out that using a real steel spring and buffer yields increased recoil at only around $15 without the damaging effects of an angry gun kit. :(

Wow..where did you get yours for $40? Now I feel like I got ripped off lol..so did you have to put buffer spacers in since the rs buffer is shorter then the KWA buffer?

Well it was more like $55 with shipping. lol
The spring and buffer set was specific for this stock so it was longer and stiffer.

This sucks, we all wasted like $50 on this lol. I wonder if the KSC GBBR M4's have these problems too, I would assume so.
Niko, do you think that a normal AR buffer with the normal carbine length buffer tube spring would give the same results as your longer and stiffer spring and buffer?

Just order the stiffer spring for your current stock buffer tube. You can even use the KWA buffer and it should ease the wear on the bolt even with a stiffer spring.

I went to the local gun store and picked up an A2 buffer and spring kit. Putting a rs buffer in works great! Its almost comparable with the angry gun kit..without the side effects of parts wear!

Told ya! lol
Glad it worked out. :)

EDIT: You could also use your stock KWA buffer with the A2 spring.  I know it looks like it wouldn't but the buffer the slide in the spring with a little force at first.  That's what I am using now.

How is the rattling noise with the stiffer spring?

I'm using the stock buffer spring..the rs spring was too stiff..wouldn't even cycle back and jus dumped gas..I'm thinking of cutting down the rs spring..maybe it'll work that way..but I'm happy with the way it is now. And there is no rattle from spring in the tube.:D

Notice how short their video demo is..cause the gun probably broke right after..and they didn't show the bolt locking back..cause it got worn out after that mag!

Ok, i put it in my gun, and did like a burst, After I did that the bolt catch wouldnt engage and i was killing myself over trying to close the bolt to open it up lol. After a while my friend was able to get it to engage, opened it up, switched the buffer and all out and put the stock one back in. The bolt catch works now too so It probably wasnt even the kits fault. Oh well, il probably just sell it and get the AR parts.

Posted 28 August 2012 - 06:12 AM

So for some reason I woke up this morning and immediately wondered why the AngryGun Recoil Kit would damage the bolt and bolt stop. I sat there thinking of how the buffer system works and how the GBBR system pushes the bolt to the rear. I think that I have an idea as to why the AngryGun kit is damaging the bolt.

With the OEM KWA Buffer and at full lock to the rear, there is only roughly 1/8" of gap between the bolt stop and the bolt. The magazine and bolt stop have only a split second to actually rise high enough to catch the bolt. With the rounding of the bolt corners, this is probably due to the fact that it didn't rise fast enough and only caught the corner of the bolt face. Then due to the fact that this is very little contact the bolt is pushing the bolt stop back down, while also rounding out the bolt.

I noticed this when I tried to install a modified A2 buffer into my gun, I would hear the bolt stop catch but it would make a slight *click* noise as it was probably hitting the corner and forcing it back down. The issue I had was that the buffer spring noise fix of expanding the diameter of the spring was causing binding issues with the A2 buffer, since the A2 buffer actually compressed the spring more then the OEM. When I reduced the diameter of the spring back to normal, the gun was able to lock to the rear and travel fully.

Now looking at the AngryGun kit (judging only by pictures and video frames), it seems that the system would reduce the amount of travel for the bolt. Now the AG buffer seems to be a little shorter, though not by much (from the rear to the end of the spring on the buffer). Then you add the length of the end cap on the other side of the spring. Then you also take into consideration that the cap just removed and additional 1/8" of travel inside of the buffer that the tip of the buffer would normally enter. So unless the AG buffer with the end cap is a minimal 1/8" shorter then the OEM buffer overall (not including the little center tip on the Bolt side of the buffer), then you just reduced the amount of travel and time for the bolt stop.

I need two pictures or measurements if someone still has the angry gun kit on the side...

1) The OEM Buffer in comparison to the AngryGun buffer with the end cap. For the OEM buffer measure from where the buffer contacts the bolt to the rubber tip, don't include that middle section where the buffer goes into the bolt.

2) The springs length

I'm probably just crazy and wrong as I just woke up haha, but if what I'm thinking is true, then we could possibly all use the AG kit after some dremel work.

I began to think of the design of the LM4 (and an AR), how the bolt travels, how the GBBR bolt is pushed to the rear, etc. I think I have an idea of why, if someone out there still has the AngryGun kit sitting on the side, could you take a side by side picture?

I need two pictures...

1) The OEM buffer next to the AngryGun buffer w/ The end cap
2) The spring side by side.

Thanks
I'm guessing that when the angry gun buffer slams forward, it's coming back with a lot more inertia than the stock buffer, and when the bolt lock engages, the buffer causes the bolt to receive more wear and tear when slamming against the bolt lock than necessary, causing the eventual break... these are just my thoughts...

The angry gun buffer is do heavy and dense that when the bolt recoils back, it's like hitting a brick wall every time. That's what is damaging your bolt when this kit is used.

Sorry guys ended up editing my other post with my full theory before noticing that you guys had already replied haha. Anyways...

Though even with the increased force of the bolt/AG Buffer if the bolt stop is at it's full extension, it would catch it each and every time and there wouldn't be any immediate significant damage. The only damage I could see would be the bolt stop or the impact block eventually deforming or the bolt eventually significantly deforming as well, not really something I'd see happening after only 1-2 times of contact that most people are experiencing.

The damage also can't be coming from when you release the bolt, since the AG buffer spring is actually weaker than the OEM KWA. So there's probably less force behind the bolt at this period since it doesn't have the momentum of the spring on the AG buffer in addition to the buffer spring, but just the buffer spring alone.

With the design of the impact block and the bolt stop together, the bolt stop can only move up and down and the bolt can only move forward and back. So if the bolt stop were fully engaging each other correctly, then it'd be impossible for it to round each other out, unless the bolt or bolt stop where severely deformed.

Forgot to mention, I have no doubt the increased weight and force is also causing the damage, but I don't think that's the root cause for it.

If it's the increased weight and force, wouldn't the A2 buffer cause the same issue?
