Hey fellas, posting here since the GII forum is too quiet. I have an over gassed GII Recon. Don't really want to go with an adjustable gas block due to barrel dimple issues.  Where can I find a heavier buffer an stiffer spring for my GII? The rifles use proprietary parts unfortuantely so I can't just use a H3 carbine buffer.  Anyone have an over gassed GII? What did you do to fix it?

UPDATE

I found Slashes buffers website.  Looks like I have two options for my GII recon with carbine stock.  Should I go with the 5.5oz and spring or the 6.5oz and spring?

If I go with the 6.5 and it short strokes is it like a traditional ar buffer where I can swap weights between the heavy buffer and my current one?  

What are you guys running?

Thanks

UPTADE 2

I ordered Slash's 6.5 oz buffer and spring combo.  I will let you all know how it performs.

What 'barrel dimple issues'?

DPMS gas block dimple spacing is not what is used on most(?) dimpled gas blocks. Close enough to cause issues with simply drilling a new dimple.

Clamp or pin is really the only solution that I'm aware of at this point.

Edit: The GII barrel (this is a Recon) dimples appear to be ~.325" apart, SLR (for example) are .4" apart. The rear one lines up, the one towards the muzzle is off.

What he said above...  Thanks for the detailed description

I figured my best course of action is a heavier buffer/spring

Slot the front dimple forward on a mill just enough to engage the front screw.

You don't need dimples at all.

Just bed the gas block with Red Loc tite.  If you doubt this, read Henderson Defense's thread on high round count guns.

You can also replace the extension tube and buffer.

I can't find a thread that mentions it, those guys certainly put more wear on their stuff than most any of us would in the same amount of time.

But...red loc-tite has a service temp of 300* max, with a removal temp of 482* http://www.loctiteproducts.com/tds/T_LKR_RED_tds.pdf

Don't temps at the block exceed those temps with sustained firing? I actually can't find anything concrete on barrel temps. Most I could find was 230* after 30 rounds through a "cold" barrel.

I have a Slash's heavy buffer and Sprinco Orange spring in my GII MOE.



They work fine.

You can use Rocksett on whatever screw engages properly and it will never go anywhere.

I have never had a problem with it at least...

What's the heavy buffer weigh?  My stock buffer is like 3.5 oz

Yes, but when they carbon up, the blocks do not move under full auto fire in volumes not even the military will ever dream about running the guns through.

They reported blocks staying in place with a simple bed job with Red.

The spacing on the gas block screws is a non-problem.

My son and I set the block and then red loc-tite on the set screws. We have had no problems with loosening or movement.

I have a GII hunter and have both the AGB and a heavy buffer (10 oz.) and the rifle has very little recoil and is more of a soft push followed by the bolt closing. The shot is very comfortable and the rifle stays on the target all the way through follow through. I have no problems with function at all. The gas block setting is the same with the OEM buffer and spring as the heavy buffer and the recommended spring to go with it.

If I had to choose one over the other, I would put the gas block on and keep the OEM buffer.

The combination of the two parts is overkill but the buffer was a pricey for us fathers day gift.

The combination of the two is really comfortable to shoot also.

Really good to know. I've been fortunate that in over 600 rounds of several different loads I've had zero problems with my Recon, but I like the way it shoots with the factory buffer and would try the gas block first if needed. Regards

SLR offers two screw spacing options (cant remember off the top of my head).  If you call and asked what they are, you can get one that is pretty dang close.  The one I bought only had the front divot about 1/4 (maybe less) of the actual hole off.  Tighten the rear set screw with red loctite, then torqued the front one.  It is solid as a rock and doubt it will move or come off unless I want it to.

G2 dimples are .295 from the shoulder and .340 in between.

I have a GII Hunter with the barrel cut to 18" and Seekins adjustable gas block installed. I've had zero reliability issues with standard buffer and spring after gas block was adjusted.

Went with a clamp on SLR for my G2 hunter.  have not installed it yet but have never had an issue with a clamp on.
