Guys, this isn't a discussion thread, this is a technical problem thread. Take it somewhere else.

Sorry to add more clutter Ty, I know you're going to be doing some more deleting.

I have two quick questions:

1) What is the front sight post on a WE M4A1? Is it an A1 or A2?:
"Models for A1, five-prong (adjusts front and rear) and A2, four-prong."

My font sight post notch is way to low (can barley see it) so I would like to know which is the correct version so I can buy the right tool to adjust the height to the correct level.

2) When installing a real-steel pistol grip on a WE M4A1, how do you deal with the selector spring? In the stock WE pistol grip, there is a little hole drilled into the grip for the spring to sit - but in a real-steel pistol grip there is nothing. Should you just "squish/squeeze" the spring in or attempt to drill a hole similar to the stock WE pistol grip?

Not looking at it atm (at work) if I recall it is the A2. If you have some 5.56/7.62 kicking around you can use that to adjust your front sight :)

Real steel pistol grips use the selector tension spring & pin hole.

I think some earlier models didn't have it, as the assembly was a bit different. My RS tango down grip does have this hole though (don't forget the lock washer also)


(if it doesn't have it, just drill it!)

Where did you get your RS pistol grip from?

I was given the same advice by Tys as well. I have the entire o-ring section covered in white lithium grease. It rarely hangs now.

Tys I plan to reverse that spring tonight, ill let u know how it goes.

Are you sure that you purchased a RS version? I have yet to buy one without the hole and I have the Tango Down, Hogue & Magpul MIAD and they all have it!!!
I did have to enlarge the opening to get it to work properly with the spring in my WE M4, SCAR, PDW and HK 416...if you don't it causes the selector to become notchy & difficult to move!

I have a real TangoDown battle grip in the mail.

Yea man, if it's real - you will have no problems (at least with Tango)

Yeah, I have a Vietnam era A1 Pistol Grip sitting on my shelf, needs a little bit of dremel to open up the selector switch spring housing to fit.

Awesome. Thanks guys, much appreciated.

Any confirmation on the front sight post - is it A1 or A2?

Mine is an A2 and has 4 sides (this is what youre asking right?)

Thanks for the info - much appreciated.

Could someone PLEASE snap a photo of their lower trigger group. I cannot figure out how to install the torsion spring properly (I forget how it looked before :() in a hope to fix my gun.

something like this Sam

Thank you SO MUCH Tys! :)

Its aliiiiiiiiiiiiiiiive!!!!!!!!!!!!!!!!!!!!!!!!!!

5 mags, no venting.
6th mag was weird because it repeatedly gave off a very faint strike despite having gas in it, and as Murphy would have it, I am out of propane until tomorrow.

Thank you all for your assistance.
