Assembling my AR - LPK Question

Which one of these is my bolt catch spring (vs the disconnector spring). I added the Bolt catch buffer/plunger for reference.



Also - how would you suggest tapping in the roll pins (Bolt catch and trigger guard) without a punch or holder. It is not going in easily and I don't want to use too much force.

top spring is the bolt catch spring. bottom spring is the disconnector spring. And of course the other piece is your bolt catch buffer.

you're going to watch a punch to do those pins, but a small phillips or flathead and some careful handwork will do as well. But ever AR is different, some are a bastard, some are not. but, I recommend a punch, and be careful not to chew up the anodized finish on your lower.

Alright, that is what I thought, just wanted to make sure. I will give the screwdriver and hammer another shot.

I have to go to bass pro tomorrow anyway so maybe I can find some tools there.

Thanks for the help.

you should try a tool store, hehe.

if you play a cloth between the punch and the pin, you can do it without scratching anything. But even colt themselves dings the receiver doing it.

I used a pair of pliers with electrical taped all over them and put a little tape on my lower. Worked the fastest and easiest for me imo.

I didn't think of it but it looks like I can get them at Sears, I will have to hit them up tomorrow. Quite a bit closer than Bass Pro.

I found the best way to send those pins home on the bolt catch and the trigger gaurd is to :

Start pin with punch and small hammer
Use vise grips with the gripping heads covered in electrical tape, several times
Squeze and lock vise grips, release, turn knob a half turn or so, squeze and lock again.
Repeat until seated
Maybe use the punch and hammer again to get it that last hair

No worries about breaking the ear off the lower for the trigger gaurd if not supported well. And no scraping the lower up hammering a punch sideways.

Worked well for me thought I would pass it on.

Thanks for the tips, I got it together. Sonic I have no idea why I didn't try that already! I was using the pic on AR15.com and they say the same thing. I was too tired at that point I guess.

Hopefully last question: I am putting a Del-Ton telescoping buttstock on a Spikes Tactical lower receiver. I am 1 or 2 full turns from getting this thing totally on (to hold down the buffer retainer) and it won't turn anymore. Is it usually this stiff or do I have a compatibility issue? I believe the lower is mil-spec, The DTI buttstock was not specified.

Well I know my buttstock is mil-spec, does anyone if Spikes's Lowers are mil-spec? If so I shouldn't be having this problem. Any help would be appreciated.

X2, the method I use as well. If you ever have any questions Ar15.com has some good reference pictures in the build forum.

+1, pliers with duct tape works real well. Ive put 4 kits together using a slotted screw driver, little oil, and pliers.

In my picture of the counter top preped for the build of 4 Del-Ton rifles on CMMG lowers you can see the laptop in the back ground with AR15.com build page tutorial up on the screen. It was a reference for the first build but the 3 after it were a no brainer.

OP welcome to BRD it only gets worse from here. haha

HaHa I agree. I started liking them a little over a year ago, I just didn't have the money to buy one at the time. I think now I could put a lower together in about 15 minutes. I guess I was just intimidated at first.

I had to go buy another buttstock because the one I got from Del-ton was either out of spec or not compatible with my lower.

Thanks everyone for their help. I got it together and I cant wait to shoot it.
