Ive found some kits online but im not sure of the quality. Anyone know anything about the deltone kits?
Be interesting to follow this thread.
I think Anony Mouse has understated his ability in this matter. He is very good at what he does.
I have built a few, different level, and probably different uses, but based on what you have stated in your original post I probably would go with the .204. I love, really love the Remington .17 but not on that platform.
I have never used the deltone kits but I bet someone here has.
I like Jack will enjoy following this one
6.5 Grendel and 300 Blackout are a couple popular alternative calibers. I'm building a 5.56, 20" slab side (no bolt assist or ejection port cover) coyote rifle at the moment. I might try a Jewell or Rock River 2 stage trigger in this one since it will be for stretching out a bit.
Amen on the extra detents. I spent about an hour trying to find one that launched during my first build.
Poly lower, spikes upper, HBAR 18" spyral 1:8 .223 wyld likes 69gr. bullets, stock trigger, however, I do extensive massaging of the trigger and it breaks at 3lbs. no creep. Cheepo NcStar 4-6x50 rangefinder reticle.
Surprising clear optics. I leave it on 10x all the time. I have a 5.56 Bull barrel 24" that I milled off the front screw on and tartget crowned at 11 degree. That's my next build.
Very nice Rhody. I have an A1 with a 14.5 HBAR, it's sure not as nice as that one.
My latest Frankengun. BCM 16" BFH USGI profile barrel, upper, BCG and BCM Gunfighter charge handle with BE Meyers 249F flash hider.
It's on an old Bushy lower, RR single stage fire control group.
KAC 600M Micro BUIS, one third cowitnessed to Aimpoint T2 on Larue QD mount.
Have been talking to a few of the AK (Alaska that is) guys, it's building a pretty good following, good fast handling close range bear medicine... basically a short fast auto 45/70.
Likely be another year or two till I build something, but I like to study things for a while before I jump in. A lot to learn. Very interesting world. I like the fact that I can build it (and therefore pay for it) step by step. Been lurking on the AR15 forum like I used to lurk on bowsite many years ago....
Beautiful equipment guys. Carry on...
A 5.56 chamber shoots both equally as well too.
If you plan on shooting mostly light grain bullets, then go to higher than 1 in 7 twist on your barrel. If mostly heavier grain and longer range, then 1 in 7 is fine. A one in eight twist is considered a good compromise much as it annoys the mil-spec purists.
Be mindful, not all 1 in X twist barrels are the same. Some are slightly over or slightly under, even from the same manufacturer. The barrel manufacturer or dealer you purchase your barrel from should be able to tell you or if you have the tools you can measure it yourself. Just use the Sinclair Simple Twist Rate Measurement Method.
It has an Area 53 'El Jefe' receiver set, 16 inch Faxon flame fluted barrel with a 5.56 chamber and 1 in 8 inch twist, Syrac Ordnance piston set, JP Enterprises enhanced bolt assembly and Nordic Components free float hand guard.
Its a good thing I took pictures because the rifle fell overboard while fishing this morning. You'd think I would learn.
Just curious, why not direct impingement and what led you to choose Syrac Ordinance piston set over others?
I REALLY like that Nordic free float tube. I originally installed an Adams Arms XLP piston system on the rifle but I didn't like how it fit under the Nordic tube. I considered the Osprey Defense piston system but they insist on a mil-spec gas block. The Syrac system required some modification of the hand guard but it was minor. After performing the mods and installation of the Syrac piston set I can say that it was easy, solid and I would use it again. You can see the piston rod in the picture above. It is the shiny silver line just visible through the hand guard.
I just realized that I haven't addressed the OP's questions...I like Delton components. The pink gun has Delton pins and springs in it. Nothing else is Delton only because they didn't have what I was looking for.
I'm very happy with how the gun turned out and I will probably repeat the build with the same major components for my youngest son. He wants Zombie Hunter green accents.
I understand the cleaner receiver "advantage" w/ a piston operating system. I thought you may have some other reasoning since there is a tradeoff between that and weight.
I can look it up, do you recall the weight of the Syrac piston set and how it compares to other available piston systems.
I ask because I am considering a piston operating system for a build my son and I will be doing for my grandson. Another "advantage" I have considered, foisting upon my grandson the additional knowledge he will gain toward piston systems, so the AK and other piston system platforms would become more familiar to him.
I moved two of these lowers into my nfa gun trust and am applying for a short barrel rifle stamp on those two.
I also went to a gun shop in Minneapolis yesterday and purchased 2 multi caliber suppressors good for 223-300 mag and one for a 22 lr and 22 mag. I now await those stamps.
If anyone is interested in the gun trust idea I went through an attorney here in mn and it was very smooth.
I put together another of the lowers with a Voodoo lower kit, magpull ctr stock, and a huldra piston upper in 5.45x39. I shot it 2 days ago and it ran awesome. I put a vortex sparc on top and a set of magpul pop up sights, which co-witness perfectly.
It is the installation of the hammer spring. DO NOT let the bottom fingers of the spring rest on the bottom of the fire control group. THEY NEED to rest on top of the pin for the trigger. They keep the trigger pin from sliding out of one side of the lower. Results of that happening are trigger pull causes one shot, releasing of the trigger causes another shot. Not only unsafe, but also makes it a fully auto per current fed regs.
I'm thinking about building one. Already have a 5.56, so looking for something different.
Although, a new bow sounds like a pretty good idea too!!
im getting a sbr 300 blackout upper as soon as I get the approval on these short barrel rifles. Also have the ability to put a suppressor on it when my stamps come back from the atf. the 300 blackout is a great round to suppress!
But here is my latest franken gun.
5.56 BBL 23" 11 degree target crown.
I've messaged the trigger down to 3lbs.
6-24x50 1" tube.
I'm hoping to find a field of ground squirrels someday to play with other than paper...
Maybe I'll move someplace where the state government isn't afraid of these things and get to own one, or three.
Been raining everyday so can't test it until the end of the week. My gun show customer I bought the barrel and mag conversion said it functioned near 100%.
I sold all my 22 Mag rifles and replaced it with the AR 22 TCM which is reloadable and about 800 fps faster than the 22 Mag. Should be right at 2800 fps with 40 gr bullets.
I had the RIA 22 TCM bolt action but sent it back for a full refund due to excessive bolt lift.
I picked up a rifle sponsor for 3 gun and they build incredibly high end ar's. Check out Patriot Weaponry.
