The E-Ring on the Shaft has already been installed for versions shipped post 12/5, therefore installation of the E-Ring is unnecessary. Please take caution, that the spring tension is reversed (as opposed to other company¡Çs dust covers), furthermore due to the position of the spring there is a possibility that scratches may occur on both the dust cover and/or the frame. You may choose to cover that area with black electrical tape to protect those areas.

The area that might be difficult (perhaps troublesome) would be to have the Gas Pipe pass through allowing for all of the other parts to align correctly. The threaded area of the upper receiver will require a little grease, lock the Delta Ring temporarily while ignoring the assembly of the Gas Pipe for now.

Screw the ring in till it does not move, if the open groove of the E-Ring used for the Slip Ring and the Well Spring aligns up in the 12 o¡Ç clock position, then adjustments are not necessary; however if they do not match up you will be required to loosen and remove the Delta Ring. Prior to removing the Delta Ring, mark the position where they all would align (with a magic marker).

When re-installing the Delta Ring, be sure to align the E-Ring and the WellSpring with the marking earlier. Once they align, secure the Delta Ring (while securing the Ring the WellSpring might move, in which case you can reposition while securing). In this procedure, the Gas Pipe can pass through, although some misalignment can occur adjustments can be made to right that, furthermore the adjustments to the E-Ring of the Slip Ring can be done easily with an E-Ring Plier. Although you can aquire the Barrel Wrench from MGC, there are minute differences in size, hence we recommend Barrel Wrenches used for Real Steel applications.

What is important is that after the Delta Ring is secured everything should align to which the hand guards can fit properly. With the Delta Ring secured the (Gas Pipe aligns with the groove) put together both upper and lower handguards, of course since the Hand Guard Cap is not secured the Handguards will not fit snugly however by putting the handguard together you can align the upper handguard with the upper reciever rails. At this point you can make minor adjustments to the angle of the handguard, in an extreme case, you would be able to use the handguards in the place of the barrel wrench, by placing the handguard onto the Delta Ring and turning the handguard you will not need to use too much strength.
