I use an O ring from the hardware store that is 9/16"O.D. x 3/8"I.D. x 3/32"(thick) just snug enough so you can still get a dollar bill to easily slip between the barrel and the stock.  It works for me.

I just picked up another package of O-rings today at Walmart. They are in the plumbing section, and you get an assortment for $0.97. Just use the one that fits around the barrel lug, two if you need to. When you can slip a couple of dollar bills between the forearm and the barrel, you have enough. I tighten the screw down hard, then back it of until it's just grabbing. The O-rings have some spring to them, and they will press the forearm against the screw enough to hold it.

I use some flat, magnetic, rubber material that I have laying around.  I form fit it to the cut out area in the forend with scissors, because I didn't like the way other setups let the forend wiggle.  I snug the screw down pretty good and have no troubles with it moving and it feels secure.

I can post a picture if anyone is interested but it will take a while.

I have had good luck using the sidewall from a blown out tire (don't ask).  I just cut the disk to fit the stud and inlet.  The tire has lasted for quite a while, gives good backpressure to keep the forearm snug, and turned my .308 survivor ( in tracker II wood ) into a tack driver.

Zeak,
  They should work fine. When you tighten the forearm down, with the O-ring in place, get it good and tight, then back off until you feel the bolt is being held by the O-rings pressure. You don't want it too tight.

O ring did not work for me , but a strip of business card in front and behind the mounting lug worked very well. This and a Harris bipod helped me a lot in bringing the groups down.  Digger

I had some o-rings sitting around here from my paintball guns...I just squeezed it down to fit into the recessed area of the forearm and then re-mounted the forearm.  I didn't torque it down tight...Just snug.

Thanks Deadeye47.  I was shooting at an indoor range, so I was limited to 25 yards.  When we some nicer weather in Michigan I will see how it shoots at 50 and 100 yards.

By the way moonlitin....where bouts in Michigan do you reside? The ex-wife moved up there after we got divorced.  Shes in Colon...seemed appropriate at the time..... :lol:

No problem on the chain yankin...I just didn't want anyone to think I was doing that at 100 yards!

I'm about an hour north of Colon...and closer to the beautiful shores of Lake Michigan!

I'll have to try to figure this new forum out, but here goes.
 
I have been using a rubber "O" ring that fits a VW case (engine).  When I switch barrels, the groups start stringing, sometimes to the tune of 6".  Here are two .357 Mag groups shot at 100 yards with a 200 gr Hornady with 14.0 gr Lil'Gun, CCI 400 and seated in the cannelure.  The lower group was shot with the synthetic forearm torqued to 60 in-lbs with an "O" ring.  The upper group was shot today with a wood forearm just snugged down and no "O" ring.

 
The aiming point was the same for both groups.
 
The same thing happened when I switched to the .223 barrel.  The group shrunk from 3" to 1.75".

I was using a Caldwell rest with the frame rested at the hinge pin for all of these shots.

Any suggestions for a cure?

Paul5388...
Welcome to the new home for H&R/NEF :D

 You are going to find that there are a great bunch of guys here. We are one big family who share the same love(addiction)for these single shot rifles and shotguns. I am waiting on my first Handi-Rifle to come in so I can't be much help on your post, but I'm sure someone will chime in soon.

P.S.
  As someone else on here has already posted, do not go to the barrel accessory page on the H&R site.
I don't even have my gun yet and I'm already looking hard at the 45-70 :biggun:    :)  :)  :)

Paul5388- 60 lbs. sounds too tight, try tightening just enough so a folded dollar can slide between barrel and forend, you want the barrel free floating.

60 in-lbs (not ft-lbs) is quite common for 1/4" bolts and screws.  It is only 5 ft-lbs and aluminum threads will stand that without a problem.

It doesn't seem to matter if the barrel is free floated if I am using the synthetic forearm.  However, I have relieved enough material in the forearm and used enough shim material to free float it the entire length, including where the farearm joins the receiver.  I got a 9" group with it free floated.

josebd,

I called NEF yesterday and the only response I got was, "send it in and we'll see."  They did re-enforce the need for free floating (being able to pass a folded dollar bill between the barrel and forearm the full length), but they didn't make any effort to ensure it was free floated while it was there for the .357 barrel.

Paul,
  If they have realized the need to float the barrel, why won't they do it when it's new? It sure could save a lot of agravation over something so simple, not to mention time and shipping costs. You know what gets me the most about your rifle. It does the same thing with either barrel. That eliminates a scope problem and barrel problem, only leaves the stock, forearm, and frame.

Don,

I think it actually points to one thing, the forearm not fitting properly.  I keep debating on what course to take to resolve the problem.  I would kinda hate to use a wood forearm with a synthetic stock, so I think I'll just have to get more aggressive with relieving material in the synthetic.  I've trimmed quite a bit of material already, but still don't have the right side with the same amount of free space as the left side.

Since this seems to be a common problem, one would wonder why NEF doesn't take the necessary steps to correct the situation instead of just saying, "send it in"?

I still haven't got to site in the new gun yet, but was wondering if any of ya'll have seen that the synthetic forend is as sensitive to freefloating as the wooden one is for better groups.

:idea3:  The stocks don't fit, wood is mis-matched, needs relief under the forends ejectors stick, rough chambers, break button sloppy and opens up when fired, crowns buggered up, bores bigger at one end than at the other, triggers rough and or heavy or both, crappy blue jobs, rediculously long throats, Yada,yada,yada,yada!  :evil:  Hey!!... NEF makes firearms that cost less than 200 da#n dollars....also they are cutting back. It is painfully obvious in that there is no Q.A. dept or final inspection departmant and they closed down the chat room as it was too expensive to operate......they are handling problems with "knee jerk management techniques".....if ya want a beautiful top drawer rifle that works and is a looker drag out your spiderweb infested billfold and buy a presentation grade  Ruger #1......that being said...geeze I love these little rifles... :mrgreen:  Ihope I can order a .44 mag barrel pretty soon before they dry up!  :toast:
