Using a pair of pliers worked for installing the bolt catch pin. I picked up a set of Wheeler bolt catch punch's when I replaced the bolt catch's with Geissele ones. They have a rubber coating on them which is nice. No muss no fuss, out with old and in with the new. If you are building from scratch and the barrel isn't dimpled for a set screw I would spend $50 or so on a dimple jig. I have them in a couple sizes. Been think about securing the gas block with a coil pin now, the jig isn't much and covers all of mine. https://brdengineering.com/pro...s-block-drilling-jig He has a video on using it, doesn't look terribly complicated and makes it bomb proof. They have other tools as well. For an upper receiver rod the MWI is hard to beat, barrel nuts, muzzle devices, etc. https://www.primaryarms.com/mi...s-upper-receiver-rod | |||

No shit. Marking up an AR receiver during assembly is a drag. It sounds like you might need a degree yourself, if you don't understand this. Shortcuts of using pliers for roll pin installation and the like- that's for people who have assembled an AR or two, and I still wouldn't do it. One slip is all it takes. First-timers are well-advised to take their time and do it right using proper tools, and then, once they've been through the process, they are better able to decide which shortcuts to take. ____________________________________________________ "I am your retribution." - Donald Trump, speech at CPAC, March 4, 2023 | |||

I highly recommend a Shooboy hammer. Randy is a member here, makes them himself, they’re excellent quality. I’m a very satisfied customer. I don’t think he’s posted lately but you could email him. Shooboy Link read the amazing comments . . | |||

I've acquired just about everything I need to properly assemble ARs over the years, but the one thing I wouldn't want to be without is that flat-sided punch from Brownells for the bolt catch pin. That thing is awesome, and there's nothing else out there like it. I can do just about everything else from my automotive toolbox if I have to, but there's no substitute for that thing. Well worth the $15 or whatever I paid for it. | |||

Yeah, there's not enough clearance when using a standard punch, unless you angle the punch a bit, which is a great way to mark up an AR receiver. Ask me how I know. There is satisfaction in doing it right. | |||

I’ve done the older ‘stripped’ lowers, put the ‘roll pins’ into place. I think that’s going away with many now. The last few did not require any of the traditional roll pins, it seemed almost to easy. I’m talking the lower. Another way to make it fun is get a few specialty parts along the way. As an example, you can get the ‘lower parts kit’ without a trigger, maybe no pistol grip either, then get one if your choosing. That way you don’t have to add a better trigger later. I got a few of the ‘velocity’ triggers, low cost, big improvement. Yeah, depends some on planned use. | |||

I actually really like that tool. I used to put the pins in with a channel lock to start and then tap them in but that is a great tool idea. It will save you you from marking/scratching your lower, as I have done. Knowing what I know now, I would have invested in a few more tools like those stated, as most are pretty cheap but make things much easier. If it's worth doing, it's worth doing right. Besides, it is an investment in your quality time together. | |||

Don’t be shy with layering some masking or painters tape on the lower. A small bump or tap will go through a layer and still show on the receiver. Double, triple, quadruple it up. Tape is cheap. -Jeff | |||

I use a double layer of black electrical tape. | |||

+1 on the tape. I use blue painters tape. The depth of finishing on a lot of lowers leaves something to be desired so as XT say...load it up! | |||

honestly, I was taught by someone that did it for a living, good bench good vice good set of barrel blocks for the vice barrel wrench (USGI is the best bar none, ) 1/2 inch torque wrench, then later if you do enough you will put that aside for a breaker bar good set of roll pin punches good set of standard punches Brownell's screw driver/ bit assortment ( you can get by with a simple big screw driver, flat blade) smallish ball peen hammer brass drift forceps, or similar to hold the pins enjoy https://www.chesterfieldarmament.com/ | |||

Come across this interesting multi-tool early this morning. Multiple function, bolt catch roll pin and front takedown pin installation tool. Good video included in the photos section at the below link. ROLL PIN WIZARD - RPW https://palmettostatearmory.co...-pin-wizard-rpw.html | |||

That's a pretty nifty tool and only $15 | |||

If you are doing uppers the one tool you need is a reaction rod. And if you aren't a normally mechanically inclined person with a decent touch for how tight is tight a torque wrench. “So in war, the way is to avoid what is strong, and strike at what is weak.” | |||

So I linked up with Chris and he walked me through the necessary parts and briefly showed me their purposes. I of course still need to take the class but it was helpful to start getting the idea of how the process works. Boss, I thought you would appreciate that he had a large roll of blue painters' tape to protect the receiver. __________________________ | |||

One piece that is a major headache reducer is a slave pin to hold the disconnector in the trigger. Geissele includes one with their triggers to aid in assembly. You could also just buy a spare trigger pin, cut it in half, and chamfer the ends. This way you don't have to try to line up the disconnector, trigger, and line it up with the pin holes of the receiver all at the same time. | |||
