Suppressor Alignment Rods for .223/.22 (All other sizes also available) When you've just received the approval notice from EFormsand get your brand new suppressor, the last thing you need ruining your day isa preventable baffle strike. Using a properly sized alignment rod ensures that your canis concentric to the bore, and catches the issue before a costly mistake if itis misaligned. Our standard sizing is designed for a close fit to the borein the majority of firearms, but we can do any custom sizes and lengthsnecessary with a bit more lead time. Feel free to contact us, nothing is off the table. Unless otherwise requested, the material willbe O2 or W2, and ends will have a slight bevel. Standard sizing is as follows: .22/223: 0.212" 6.5mm: 0.250" .308/7.62: 0.295" 9mm/.357: 0.344" .375: 0.359" 10mm/.40: 0.386" .45/.458: 0.438" These calibers are all 12" lengths unless otherwiserequested. I can do nearly any custom size, but certain ratios of length to diameter cannot be guaranteed straight after shipping (extra long .17 or .22 caliber rods) .50 BMG, 20mm, and other large bore projects will be sizedas requested by end user (I can advise you if you're not sure). Standard lead time is 2 weeks for anything I don't havepre-made, but I keep a decent supply of 223, 6.5, 308, 9mm, and 45 acp stocked.
