    I wasn't experienced on the first lower I built, I read, read some more, watched some videos, got the proper tools, took my time and it all went fine. Now 30+ lowers later I have never used a clamp, vise grips, channel locks, etc. and I have never had a issue installing a roll pin with the proper punch.

    Basically you're implying that if you are unexperienced it's ok to cob it. If it was a better method or even close to being an equally as good method there would be a professional somewhere using a c clamp to install a roll pin - it makes me laugh when I type it. I will say it again, it's your lower, install the roll pins with an electric toothbrush if you like. Just realize that the professionals have been doing it with a hammer and punch for 40+ years so there must be something to it. Good luck.

    Experienced armorers use hammer & punches because tooling setup is quicker and they've done it enough to develop a good feel for the process to perform it without error

    Regarding the c-clamp vs proper tool debate- for my first build this weekend I am going to try to do everything by the book and use the proper tools which I have already purchased anyway. Actually they came in handy already for disassembly and reassembling a couple of light/heavy A5 buffers to create a standard A5H2. If I encounter issues at any point during the lower assembly I will stop, read more, and if for the sake of the build I feel that using a c-clamp is safer than continuing to struggle with my pin driving technique I will give it a try.

    And I will use lots of blue tape

    Question

    not sure if this qualify as "build related"

    I bought a BCM 16 Lightweight Mid-Length Rifle ( MID-750-LWC ) from G&R and very happy with the build.
    Now getting curious if possible to replace the upper receiver with a HK MR556A1.

    Is this even possible?

    thanks in advance

    I have mod kits that thread the rear detent hole so that one doesn't go flying if/when you are assembling your lower or changing out the rear plate. It's the same that Seekins puts on their lowers.

    This grew out of my needing to buy a replacement rear detent...

    ETA: No, I am not claiming that Seekins uses my kits. Just reread my post and wanted to make that clear.

    i'm not saying one is better than the other. they both seem to work. you've still given zero support for why one is better than the other. surely you realize that the same amateurs that scratch their finishes with vice grips also scratch their finishes with roll punches and hammers? and you seriously expect us to believe that more people crack their receivers with vice grips than hitting them with hammers? come on now

    stop appealing to the authority of nameless professionals and explain what exactly the difference is.

    Proper technique versus improper. How about this, find a gunsmith or armorer that uses a c clamp to install a trigger guard roll pin. Manufacturers, armorers and gun smiths alike all use a punch to install pins, what more needs to be said?

    It's like the guy that defends his DPMS claiming it's as good as a Colt, he will defend it all day long so he doesn't have to admit he bought junk. People don't like admitting they are wrong or made a mistake. I can't say it enough - use anything you want to work on your guns it's your perogative. Please don't try to justify it here, a newer member might read it and think it's ok and/or the proper way to do it. We should not be spreading misinformation here, this is supposed to be the "good" site.

    In the mean time I'll just continue to use the proper tools and technique. Good luck.

    Fair enough warner41. Hard to argue with that logic. As a (former) mechanical/process engineer myself I would agree, proper tools and technique are first and foremost. That said, because most of us are not smiths or machinists, it is important that we admit our limitations and know when we are pushing the bounds of our skills and are on the verge of fouling the part we are working on. As I said before, I did purchase the correct tools and have every intention of using the preferred technique, but plan B is to try an alternate method if I have trouble, and plan C is to hand the job over to a good gunsmith (one that I have already reached out to and have arranged to check out the gun before it is test fired).

    By the way, the waiting or parts is interminable. Today I got the package that was supposed to contain my castle nut and A2 spring (along with the pieces of the LPK, barrel nut and delta ring, the last parts I need) only to find Brownell's had run out of spring and backordered it. Luckily I found a Springco green spring elsewhere but now I have to wait for that to arrive...

    ...and on and on it goes
