Bore Alignment rod overview. Cheap alternative!

[@lawrenceminnear2705]

I have been looking for such a thing. Thank you. I placed an order immediately after watching this. I would not be suprised if companies are buying these rods and selling them as alignment tools and making and making a lot of money!

[@wtfmrkratos]

.2031" - P/N 8890K185 - Good general purpose rod for 22 caliber suppressor alignment. This should work well for distinctly undersized match .22LR bores (think CZ452/455 at .210-.212" bore diameter & target ARs) but otherwise may be a slightly loose fit. .212" - P/N 8890K189 - BEST FIT for many standard, tight 22 caliber bores (.22LR at .217" bore diameter, .223/5.56 at .219" bore diameter, etc). Good fit for PSA AR & Ruger MKIII. .2187" - P/N 8890K191 - Alternative for older, loose 2.23 / 5.56 bores. This might be too tight if barrel is dirty. Close to Geissele rod at .2175". .234" - P/N 8890K195 - Alternative for tight, undersized, match 6mm ARC bores. .2343 - P/N 8890K207 - BEST FIT for many standard 6mm ARC bores. .250" - P/N 8890k213 - BEST FIT for 6.5mm Creedmoor/Grendel bores (.256" bore diameter). .250" - P/N 8888K361 - Alternative if above is out of stock, uses A2 Tool Steel instead of W2. Same dimensions and tolerances. Hardness rating increased from Medium/Rockwell B95 to Hard/Rockwell B104. .295" - P/N 8890K227 - BEST FIT for tight 7.62x39, .308, 300BLK and most Western 30 caliber bores (.300" bore diameter). Good fit for CZ 527. .2968" - P/N 8890K228 - Alternative for oversized, loose .300 blk/ .308 bores. Tiny, tiny bit of play. Too tight to fit CZ 527. This is also nearly identical to the diameter of the Geissele rod at .297". .339" - P/N 8890K239 - BEST FIT for tight 9mm bores (.346" diameter). .3437" - P/N 8890K241 - Alternative for loose 9mm bores. Perfect for Scorpion & CZ-75. Little bit of play in Uzi & G19. .4218" - P/N 8890K259 - Alternative for loose fit for .45 ACP bores (.442" diameter). Too much play in DW 1911. .4375" - P/N 8890K262 - BEST FIT for tight .45 ACP bores. May generally work but could be too tight for rare cases. Perfect for DW 1911

Great information Dominic! Thanks for adding to the post!

[@zernebog661]

Wow thank you so much. Info no longer site. Appreciate it. And input for -.40 cal

[@Anon585]

Bought one!

[@ibstro]

Thank you for all the detailed information. Really appreciate your time and energy on putting this together.

[@wtfmrkratos]

@@ibstro no problem!

[@seanihde]

I'm new to the can game. I just got my first one out of jail (2 day wait!). Thanks for the suggestion on the bore alignment. I ordered 5 rods, it was about $5o including shpping and got them in 2 days. I test fit them and everything seems great.

[@Kycirion]

Did this too. Bought rods for 6 calibers for the price of a single Surefire rod. Plus after cutoff I have lathe stock.

[@BafflingBS]

Thanks! I bought the 22 and 300.

[@sand-paper-pistol-grips8248]

I used an archery arrow and found one just under .346” and wrapped scotch tape around the shaft in two places until the arrow fit snug but not too tight and it worked great. Bought the arrow at Academy and it was cheap.

[@AnthonyOrantez]

Thank you for this

[@tothepoint4240]

That Sammi site is a great resource! Thank you

[@choppercos508]

Helpful video, thanks.

[@christophernelson9666]

I have never once and granted. I only own two suppressors but I have never once had a problem. Just looking down the bore to see if it's in alignment

[@highdesertutah]

You should pin Dominic’s comment with the rod sizes for each caliber. Thanks for the info!

[@zernebog661]

Small chance that you’re still read this but if you are. It seems they have taken down most caliber sizes on the website. anyway you can help with getting that data. A copy of the diagrams. Looking for 9, 40, 45, 223/556. Thanks in advance.

[@blstic2a]

Hey bud all the information is still there, you just need to know where to look: saami.org/technical-information/ansi-saami-standards/ make sure to select the table that corresponds with the round you are looking for.

Awesome Sauce

[@TCM308]

Thanks man

[@obxburg]

Great Job Sir! It’s almost hard to believe that you only have 80 subscribers. Do you have another channel? If not, you should. Thanks again

[@scottd8555]

What sizes did you find to be perfect for 5.56, 300 blk and 9mm?

[@bbc91camaro]

Ive got an ar10 in 308 with a hybrid 46m. Im using the asr mount and the muzzle device uses the shim kit it came with but i noticed the shim is crushed and is coming over the shoulder of the barrel. I used the rod you suggested and it isn't touching but its definitely not perfectly centered. My question is is it possible the shim is causing this to not be aligned better?

[@Supernova73178]

how did you cut it in half?

[@bbc91camaro]

Any chance of getting some help figuring out what rod i would need to check the clearance of a 338 Lapua Magnum?

[@lucabarbieri6457]

Hello, thanks for this very useful and interesting video. Did you order a O1 Tool Steel Rods of 0.212" for a 22LR? Thanks in advance

[@blstic2a]

See comments from Dominic please

[@TXMAC]

Thank you for sharing. Looking at the list now to purchase a couple. Wanted to check with you and compare. Did you order 0.212 for 223/556 barrels? And 0.29 for 308/762 barrels?

[@blstic2a]

For .223/5.56 the bore diameter is 0.219 so I ordered the 0.2120 drill rod. It was the perfect size. For .308/7.62 the bore diameter is 0.300 so I ordered the 0.2950 drill rod. Although I'm sure the 0.2900 will work fine.

[@TXMAC]

[@jack-ui3ob]

@@blstic2a thank you for your video.. I just want to double check before I order the drill rod.. I have a 5.56 which is a 0.219? So I need to order a 0.212? I have a 300 blackout which is 0.300 DIA? So I need to order a 0.295? I have a 7.62x39mm is it the same as a 308 WIN? So bore DIA is a 0.300? So I need to order a 0.295? Thank you please help.

[@jb9371]

Which one did you end up going with for 9mm?

[@KS_Penetrator]

I know I’m late to the party here. But we’re you having bore alignment issues with your stribog? I know of myself and another individual that have had issues specifically with the stribog

[@blstic2a]

No I was not having issues. That said I didn't use the stock barrel. I swapped for a shorter ILWT barrel. Still no issues and shoots very well.

[@duraznostj]

Where did you find the McMaster-Carr print-out?

[@tylerbowen2692]

Lol pretty sure the rod was touching the suppressor until you used your index finger to center it

[@SneakyKittyGameDev]

Its that magical thing called gravity, the rod had some extra clearance allowing it to move back and forth. You can see when he puts his finger on it to move it to the other side/center it it does the same thing on the opposing side, its very close to centered.

[@talibanterrance8134]

why wouldnt you go over the diameters of the other caliber rods other than 9mm?....

[@Witty76]

Great job. Just looking into this myself. McMaster keeps coming up as a great alternative to the stupid expensive versions. So which rod size did you choose for the 9mm? Thanks again for sharing.

[@blstic2a]

9mm is 0.346 bore diameter. So I went with 0.3390 drill rod. Worked great! I used Multipurpose O1 Tool Steel

[@timstrand282]

@@blstic2a hey bud good work! In the vid you said for the 9mm you went with 2 sizes…the one you just mentioned and one a tiny bit larger. Do you still recommend the smaller of the two? Did the larger one not fit through properly? Thanks!

[@blstic2a]

@@timstrand282Hey Tim, so I also bought 0.3438 to see if it would work. It does fit down the barrel but its pretty tight so I don't use it for bore alignment purposes since its hardened tool steel it might damage the barrel. The 0.3390 works perfect!

[@juncho1977]

What did you use to cut the rod?

[@blstic2a]

cut off wheel on my grinder. I'm sure you could use a hacksaw also. Rounded the edges with my bench grinder.

[@ecobasetech4558]

This is great and all but not everyone has a grinder or know how to use one to round off the end like you did. Also, would have been nice to know what exactly you used to cut the 3ft lengths of rod in half.

[@kruiser5004]

Hacksaw or a Dremel will work, to cut and to chamfer the ends a Dremel can be used, or if you have a lot of patience a file.

[@rilo_dippin3650]

What barrel are you using?

[@blstic2a]

ILWT - 9MM

[@ronburton7611]

Mine had a definite bend. Waste of money

[@Kycirion]

Send it back for replacement they guarantee .0005 runout.

[@quickdrawmcgraw4394]

Runout is different than straightness. Runout would be concentricity. The diamater tolerance for these is +-.001". The straightness tolerance is .005" over a foot. In my mind depending on the fit the barrel will keep the rod somewhat straight up to the exit of the barrel. Then If you're suppressor is less than a foot you should be able to tell if you're safe or not depending on the difference of barrel and suppressor bore.

[@snivesz32]

I don’t get it. Why would it not be aligned? And if it weren’t, there’s no adjustment to make, so what’s the point?

[@blstic2a]

maybe this video will help: kzbin.info/www/bejne/h3LboqCBiZh_aM0

[@steelshrapnel9900]

I guess this video ok for garage gunsmiths but not exactly good advice! Reason bore rods expensive due to top level CNC procedures uniform tolerances from end to end on high grade materials cost considerably more than what McMaster - Carr offers! Expensive bore rods have excellent quality control measures you’re not going to find with cheap rods designed for other purposes! Top level CNC machining of high grade materials guarantees precision and durability for accurately measuring clearances with wire filler gauges, thickness shim gauges, micrometers, and calibers! Rolling McMaster - Carr rods across table top to gauge uniform concentric is ridiculous advice use for identifying bore center alignments for suppressor use! “Two different size rods for 9mm”, Really? LOL
