I know this has been done a lot before but I thought I’d show mine since I’m working on a pistol build like others on here and wanted a short gas tube for it. First I’ll mention the collar I went lazy and ordered one from MSC direct. (13/16” [.8125”] bore size) took it to 22.0mm (.866) I then went to school to machine the swedge. I was given what I was told was 4140 chromoly but half way through an other instructor said it was actually 1144 stress proof. That’s the fun of unlabeled metals in the shop I guess. Turned on a Harrison M300 which is a good medium sized lathe for the job. Quick par

Sorry for the dumb questions I figured out the trigger spacer. Can anyone tell me if I dimple the back holes for rear trunnion. The long swell necks seem to fit in one side fine but its definitely not dimpled. So would I hurt the spot welds on the square back reinforcement plates by dimpling?

So I started this build with a Nodak Spud LLC square back psl receiver and the 15 piece psl armorers kit from Center fire systems. Since this is my first battle with these beasts I was hoping to get some advice. How necessary is the psl trigger spacer washer to the alignment of everything, do I need to buy it and also if any one knows where it goes, left or right of trigger on axis pin? Also the bolt carrier seemed to be way to hard to push in when assembling or when the gun cycles. Im aware AK variants have their hang ups but this seems like it will cause the gun to lock up each shot.

Got the holes finished but still waiting on 2 blue and 2 green vials plus Norland 61 compound and 365nm uv light Trijicon Chevron

After ordering the 2x6mm Ice blue vials for mbus rear the other day. I wanted more for all my rifles and pistols without tritium or with dying tritium. What I found readily available- 0.95 x 3.0mm (Green only) 1.4 x 3.5mm (Green only) 1.5 x 6.0mm (All colors) 1.6 x 4.5mm (Green only) 1.55 x 5.0mm (Green, Ice blue, White, Yellow, Orange, Red) - $7.50/ each The sights Im going to drill and fit for these are between $5-$15 so no biggie if I mess up but if done properly then it seems like night sights could be made for a very low cost, givin it wouldn't be trijicon quality.

Thank you for the feedback and advice. FunkedOut did a seriously great job making those sights out of 7075! Thanks for sharing that too. And three of my other pistols are green on green so I been wanting to mix it up with something different. Also a website mixglo.com has some vials with reflective paint one side to make the vial glow brighter, this idea might be a good way to make duller colors pop for the front post. And could you explain the whole hollow out the base thing for powering fiber optic U? That sounds like a project I'd like to try.

Hi all, so like the title suggests this is a do it yourself thread for tritium night sights. Before starting these projects I did a lot of research and this is what I found. Tritium gas is kept in boroscillicate glass sometimes at high pressure. It was easiest to start with polymer sights so I picked a Magpul mbus rear sight. I highly recommend this sight to start with since it has two divets that act as pilot holes for 2mm diameter tritium vials. Other then the sights and vials, all you will need is a drill press with x y vise and some loctite glass bond. I bought 1mm, 1.5mm and 2mm 2 f

Drooling over here damn! Man this is clean as well! Thanks are you building a cat12 also?

It started to run the 2 3/4 1oz 7.5 shot with out hiccups today. $7.95 a box at local shop Before without 4 port gas plug, it really liked 2 3/4 1 1/4oz 4 shot. $12.95 a box It of course enjoys 00 buck and slugs

This is my Century arms C39 version 1 I bought it brand new almost 3 years ago and have ran this thing through the mud and back with friends. Over 4k rounds and only one ftf due to primer seated to low. This gun by far was the best budget AK variant. For $650 at the time for lighting charging handle and enlarged mag release was what got me. Then I fitted Vltor ak buffer tube and Troy alpha rail real easy. Also has Ultimak gas tube, Alg flat bow trigger and Krebs safety. These guns are not only 100% american made (good or bad for some) but they have concentric barrels and tag teamed with Ultim

Its done now to have fun this weekend

So for this Catamount fury 1 conversion I have gone the easy route with CSS parts. This is a pictorial of what I did. I started by testing the shotgun with some different loads to make sure it would cycle. I then gutted it down to the receiver, barrel and gas block. (and trunnions too) its much easier to work on of course. So then I went at the rivets. I flatten them down then made pilot marks and started with 5/64 working up to 3/16 and I used Dewalt carbide bits and drill. Once the rivets broke off then I tried to carefully brake the tac weld on the back of the trigg

Hey cat owners I just bought a F1 in the last two weeks, shot it three times and then tore it down. I have all my css parts on the way. I was just curious if anyone has tried to swap the mag release with a saiga or vepr extended one? they seem to be very similar

was this project ever finished?
