Hi,

I would like to fix the shaky front part of my TM M4 to make it sturdy,

Any advice?

Thanks,

Thanks, what is the Lonbow option?

What I did with mine is stick a small shim - cut from a pop can - and wedged it between the block (that connects to the upper receiver) and the outter barrel (which inserts into this block secured by like 3 small screws). I found most of my wobble was due to the gap tollerances being very low. You have to experiment with the shim size (mine was approx. 1cm x 1cm or smaller) so that you have a nice snug fit.

I baught the TM RIS unit and after it was installed it was pretty solid. However I had to add a PEQ for the battery and then it became rediculously, and uncomfortably front heavy. A crane stock will balance the gun out very nicely.

When I first received my TM M4, it had a bit of barrel wobble. Turns out the problem was the collar connecting the barrel to the upper receiver was loose. Since I tigthened that, I haven't experienced any barrel wobble whatsoever.

Unfortunetly I have no information for you in regards to what a lowbow is. My recommendation is to either get a 1 piece metal barrel and metal body or invest in a 1 piece metal barrel and get a casv front end.

The "Longbow" was one of the few aftermarket replacement front end kits that were available at the time of the writing of that barrel wobble solution guide.

Since then, a huge plethora of aftermarket front end kits have been made available, from free floating barrel kits, to just really sturdy all-metal kits.

Thanks for the input, I going for a CASV. Any worry ahead with custom?

[TokyoSeven]

Casv should be fine.

[Long_Bong]

Now, would it fit with a metal body or since I believe that we need to remove the upper rail, I would need a body with a removable upper rail?

[TokyoSeven]

Thats something you will have to research for your self depending on which body you choose to go with and which front end you choose to use.

A casv simply goes over the existing rail on the upper reciever.

Thanks, so it will go over the rail of the metal body
