New Build Recoil

[LRRPF52]

The 18" MLGS is gassed pretty hard, much more so than a RLGS, so you will have to address it from a number of angles. If you are comparing a traditional set-up AR15 in any centerfire caliber to a JP LMOS with SCS with adjustable gas block, it is going to have more perceived recoil no matter what you do.

The JP LMOS + SCS + Adjustable Gas block feels like snot on a mirror, sliding inside your rifle, but with nothing moving in your reticle. It's a beautiful thing to behold, and feels nothing like shooting an AR15, which is already a very mild recoiling system with in-line recoiling and reciprocating forces.

I'm in the process of several 18" MLGS projects. Here is how I am approaching them:

I already know they are gassed hard, so I have an array of several different buffer and spring options.

* JP SCS for AR15 with standard spring weight captivated from the factory
* MGI RRB, with spacer for rifle tube, as well as carbine and rifle springs
* H2 buffer with carbine springs
* Spike's ST-T2 buffer with carbine springs

I'm still looking at buttstocks, and have a bunch to choose from, but I will be focusing on reliability, accuracy, and weight/balance. I want the JP SCS to work because it feels so amazing in these rifles. With 18" MLGS, I will be using some method to dial down the gas, and I am looking at the RCA adjustable gas key and Lo-mass BCG right now, nitrided.

I also have a Seekins ATC muzzle break, even though I'm not a huge fan of breaks for practical use. I'm considering installing it on one of these 18" guns.
