I didn’t remove the barrel so it didn’t have to be timed for head-spacing. Simply remove the Handguard and then the barrel nut then re-install new. Super easy.
Bolt hold open is virtually useless in every aspect, especially competition lol. Buy 40rd or greater mags.
Taylorfreelance and MBX mag extensions that get to 55-60rds.
I will agree, their decapping system is better than any other die Ive tried, from Lee, Dillon, Lyman, even Redding. I do wish their made their die with a little tighter neck tension myself though.
For me, I opted for the first model I could get lol. I actually like the MK3 HG, but it was too heavy for me. This is why I switched out the HG to a Smoke Composites. I also switched out the buffer tube just to match the Smoke HG. I hated the Hogue stock/grip so I changed those as well. Right now my JP5 is lighter than the SC Model.
