Good Day all, I am putting out a feeler for how many would be interested in such a product. Titanium is a bit softer than steel in relation to density, so over time the "teeth" that engage with the hardened steel detent will wear. However, I have also noticed this also taking place on steel caps as well. I've also seen Aluminum magazine caps on cheaper turkish guns that engage steel detents, which hold up over time (albiet with a bit of deformation also). Why Titanium? Well, it is about 50% of the weight of steel (the end cap is fairly heavy). And it is very strong. I would also copy the OEM design exactly as is, if it ain't broke... I can offer a cerekote graphite black on it to replicate the OEM colour scheme. EDIT: If you are interested, please visit this page and sign up for the Ti Cap so I can get an acurate idea. Thanks! https://www.rxarms.com/out-of-stock

Thanks I’ll have to look at it

I am still considering to undertake a foregrip/hand guard. I have not had the time, nor am I sure I want to commit the finances to such a product. One of the best thing about the M4 is the takedown without tools IMO. There is currently no after market handguard that accomplishes this feat while also giving some mounting options.

Yes PayPal is a rip off I’m trying to find another way, but I’m a small time guy and PayPal provides shipping and e commerce in one package which makes things very streamlined for me. I’m sorry the conversion sucks.

I will put value under $100 on customs

I have started to email out to the waiting list to purchase. I will give a few days for waiting list emails to purchase on a private link, after that I will open up purchases to all.

I’ll measure them again once I get them back from Cerekote, they are done actually, should be available to sell within 2 weeks.

They are getting cerekote right now…. Maybe 2-3 weeks.

When I get them back. I’ll email out to waiting list.. no pre order.

Got the raw handles in, now to send them off for cerekote.

?

This can easily be designed to stop the handle from over inserting. I have made this design on mine, it cannot be overinserted, it is simple engineering where the handle tapers to the pin, when properly designed the handle cannot go too far (even when the detent is not engaged). Surprising that some manufacturers continue to have issues with over insertion.

I will once I get the raw handles from machine shop. not sure what deep means, can you explain? As mentioned new handles will be 0.2” longer and a diameter a bit less. Might be what you are wanting.

The trade off is bigger handle less length, I don’t think I’ll be making the first version again so u got a keeper if you like it a bit bigger. I’ll post a pic when I get the production back, I’m probably 3-4 weeks away from cerekoted handles

I’ll discount one for you also if u want the next version also. Thanks for your guys’ support! I am also making a minor adjustment on the hole size for detent, making it smaller for less play, so should be tighter fitting. final handle length is increasing 0.2”, should be enough handle length to assist in clearing the fatter bolt release buttons. Once I get a working version I’ll get a better idea on the outside diameter, as knurling adds some, but expecting from 0.55-0.57” for handle diameter after knurling.

Yes email me when they are available and I’ll hook you up. Like I said I don’t make much on these but I’ll see what I can do!

I have ordered material for the next run. I am going to make the handle 1/4" longer, but the diameter will be a bit smaller (as mentioned, to keep the weight at OEM spec). I will not exceed OEM weight as that is important to most, so I want to keep that spec intact. Still working with the machine shop to determine the spec for handle diameter. I will report back when I have more firm specs. This should alleviate all the short handle issues that some may have when combined with bolt release pads that extrude a bit. -Robb

Thanks for the kind words. I know that many have different priorities… some want a larger handle and don’t care about weight, some care about weight and not larger handle. Then there is the whole “locking handle” vs “spinner” vs “semi locking but not really”. I am a methodical thinker by nature and am trying to satisfy everything which was my goal in this handle. As it stands now I am not sure I have enough demand to Make another batch… so for now I am waiting a bit more until more express interest. It is a very expensive product to carry in unsold stock and get stuck with inventory.

materials prices are up quite a bit in the past 4 months, i'll need to increase the price on the next batch unfortunately. This is a very low margin product for me to start with. I mostly did it as I really wanted to have it for my self and I'm glad others enjoy it also. I'll be posting updates on my website (rxarms.com) for the progress of the order, I'll be likely ordering metal next week. I'll also be making a small changes to the v2 design. One, I'll be making the diameter a bit smaller, and extending the handle out 1/4", with the goal of keeping the same weight, but making the handle a bit longer (the diameter needs to reduce to achieve this). I am guessing new diameter will be around 0.57" instead of the 0.6" but we will see. thanks again for all the support.

From my testing, what you are seeing is just the metal edges wearing in from a freshly machined edge. I have removed and installed mine many times over and have not noticed any significant deformation. It is RC40 hardness on the steel tang and will most definitely hold up much better than the titanium equivalent. Please let me know if you have issues in the future. yes it’s a pain the ass to remove, that is how I designed it how often are you removing the bolt? You can be confident that it will remain in place under any circumstance.

Yes I have less of a taper for inserting into the bolt, trying to save as much weight as possible. Can easily be inserted if you rotate the handle at the same time as pushing. Pushing straight in without rotating is more difficult. as for the bonding/affixing method… a proprietary technique known only to ancient dwarven blacksmiths nice collection, I should point out only mine in that group matches slightly less weight than the OEM handle while giving benefits of hardened steel tang and ultra light and much bigger handle.

I modified the pointed end to save weight, I was on a major weight saving mission, pointed end was a waste of weight.

Not sure what the problem is, looks normal to do me, send me a PM, or email me at [email protected]. to insert it into bolt, push and rotate.

Man looks better on your gun than mine! I am out of stock on black, have 1 or 2 Ti colour left, working on getting another batch made this week.
