My journey from this:
How? I hot rodded my SOCOM with Sadlak Guide Rod, Tin piston, Vltor Mod stock along with SEI tack bolt stop, Sadlak tact mag release and pic rail on the sling loop holes. Before this, I shimmed the gas system but really found no difference in accuracy.
I stripped the SOCOM down, cleaned it all and then down the barrel I ran wet patches of Butches Bore Shine, wet brushed, wet patches, dry patches, etc until clean then a patch of Butches Bore Oil, this is the same cleaning process I do with my bolt guns. Dabbed on SuperLube and back together with new parts. I had a problem with the Vltor stock, I could not get the trigger group to seat and snap in. With the factory stock, the trigger would practically fall out / in but the Vltor this is a nice close tolerance fit. Plus, the Vltor stock does not flex and twist like the SAI plastic stock. This was very noticeable with the barreled action removed and even put together, the Vltor has less flex.
This was my second day out and both days produced similar results so with 150 or so rounds down the pipe, I feel confident accuracy has improved.
Pix 1 was my average group with my SOCOM16 out of the box that has frustrate me from day one. This was one shot at a time as slow of fire rate as I could concentrate on. That is an 8" target and as can be seen, poor accuracy. Holes missing the 8" target into the cardboard. Some of you gave me feedback that I lacked shooting fundamentals, OK I not a one holer but I am also no rookie but I can say with out regrets, my SOCOM was junk from the factory and that I was not the issue.
Pix 2 is 3 mags loaded up with 10 rounds for a total of 30 rounds. Each mag was slow fire for the first 2 rounds, then as soon as the red dot of my EoTech touched center I pressed it off for a moderate fast rate of fire. As you can see, a smaller target of 6" and not 1 of 30 rounds missed the black. Did I pull a few, of course but still 10 rounds in about 12 or so seconds over 3 mags hit inside of 6" is a vast improvement.
Pix 3 is slow fire for accuracy and yes I did pull one but that if a far cry from all previous groups. This is just one target but this is my average slow rate grouping size now after five 5 shot groups. No comparison between pix1 and pix 3 accuracy results.
Some musings on what I learned. My SOCOM is very finicky about the ammo it eats and now with the upgrades, things have changed. HSM 150gr ammo in the camo box, SOCOM likes this ammo. This is what I shot today. Cost is $9.00+ for 20 but shoots very well in my SOCOM now. AE150gr was not a bad ammo before but now the SOCOM hates to eat it. Groups were not all that impressive but still better than before hot rodding.
Ejected brass now lay in a small pile around 90 degrees from the muzzle, not thrown all over the ground, in front, behind ect. from 25-150 degrees off the muzzle.
Old factory plastic stock my recoil jumped like it was free recoil, up and right, left, all over. With the Vltor, I can spot my splashes on many occasions with the shoot and c, no left or right jump, straight back and not as much muzzle rise.
The guide rod is a major improvement, can not explain it but the bolt movement even firing a round just has a different, more better feel.
SEI bolt stop, this part so stupid good I cannot understand why every M1A does not have one. I love this part. Guess it comes from my M16A1 days.
Mag release is also a good improvement, not like the guide rod or bolt stop but still a good improvement. Again, all M1As should have this.
I wrapped up 2 point sling around my forearm and then I did get a left muzzle jump but not like the factory stock. Just saying with the Vltor, shoots just like my bolt guns, rearward and I can spot bullet splash at times.
Last summer I shot with some AR guys and was embarrassed to say the least if you consider pix 1. Today AR guy was there too and now he is embarrassed.
I finished the day up shooting at will. I hit 4" metal plates set in the ground from 40 yards to 100 and only missed one, 75 yards on the first shot. I hit some wood I stood up in the ground, hit some small bottles around 100, could not see tennis balls, split a few trees limbs, just a fun day that I could not have done before.
My EoTech is now my limiting factor. I find it very hard for my old eyes to repeatedly dissect a target with an EoTech. I am going to try a Vortex PST as soon as I can raise the fun money and believe this will help improve accuracy quite a bit too.
