Hi all,
I have a g&p sr15 that I am looking to modify and I need some assistance.
I have never modded anything that falls under the "m4" bracket, so this is a first for me.
What I want to do so swap the outer barrel so that a suppressor sits either flush against the end of the handguard/rail system, rather than further down at the end of the outer barrel that protrudes out of the rail system OR install a suppressor that is integrated underneath the rails.
I also want to swap the "DMR style" stock for a standard AR style buffer tube so that I can put a crane or similar style stock.
Images below: top is current setup, bottom is what I'm aiming for.
Regarding the stock; I took off the dmr stock and I tried to attach a random m4 stock from my brothers old Asia Electric Gun SR15 (same model, different manufacturer mind) but I noticed that the bit that protrudes at the back of the receiver that guides the stock tube in place was considerably shorter on the g&p than the Asia gun. I screwed in the stock tube but when the screw went in all the way, the tube had around 1 or 2 inches of play, sliding backwards and forwards.
I then tried to install the shorter outer barrel system from the Asia sr15 onto the g&p sr15 but it was slightly too wide to slot into the front of the receiver.
I am now trying to find a stock tube that will fit and an outer barrel that will fit.
The outer barrel I'm after is around 13" I beleive (current stock barrel is 17").
Is there any specific tube or barrel that I need? Will it have to be g&p branded or are there certain compatibility with different brands?
Can anyone assist?
