rail recommendation

[whit]

Im looking to make a gas piston imitation m4. What rail system do you guys think will go well with the madbull Adam arms piston. ? Bare in mind it has to be 7 inches.

Long as it's not got a very narrow channel underneath the 12 o/clock rail I reckon most stuff should work.  You'll want to be careful if you look at anything from Madbull, a lot of their models have a pin across the gas tube channel (which could be easily cut out) but some models have that entire space filled with solid metal.  Can't remember for the life of me which ones now which is annoying.

 

I'd avoid a quad rail personally, I have the same kit in a mid-length and just the gas block, cylinder and piston weigh a lot.  Not sure if your budget but here's a couple of options I think might work:

All the Madbull Troy rails (including the Viking Tactics ones) have the top-section filled in, but even if they didn't they're quite cramped inside.

 

The Madbull Daniel-Defense rails leave a short section of the top un-milled to block the gas tube, but this can be cut out with a Dremel and a steady hand in about half an hour if you want it to look nice.

 

The Madbull Noveske Rails have a little aluminium pin which can be punched out in about 30 seconds.

 

I can't remember what the Spikes-Tactical rails have, sorry

I actually fitted this onto my real AR15 with a CMMG Gas piston kit, with a few modifications (it wasn't easy).  But got there in the end.

 

Should fit an Adam Arms Piston kit no issues.  CMMG has a continuous gas tube half way down the barrel, hence the top channel required some "enlargement" to fit the gas tube.   Adam Arms looks to be a short stroke piston (like the 416) with no gas tube and shouldn't need much enlargement.

 

Its a very high quality rail. and Would fit a DI AR15 without any major modification.
