![]() Lane’s disappointment and subsequent anger at the range of books available led him to found a company – and change the world.Īnd thank god for us poor readers that he did. His choice was limited to popular magazines and poor quality paperbacks. In actual use, the PSR and Dual Lok suppressors have pretty similar length in front of the muzzle face, because the PSR's are 2" further rear of the thread shoulder.Not too much to ask, was it? It was in 1935 when Allen Lane stood on a British railway platform looking for something good to read on his journey. The alignment quality of the PSR interface is identical to a perfectly manufactured, brand new Dual Lok muzzle mount interface, but the second interfacing diameter constrains the PSR system to this alignment accuracy forever, whereas fouling and damage of the Dual Lok muzzle mounts could potentially reduce their mounting accuracy which is part of why they are shorter with slightly larger bores. The 5.56mm model is not recommended for any use on muzzle mounts outside of the PSR series mounts. The PSR's can take std muzzle mounts but due to the fact they are longer than std DUAL-LOK suppressors, and have slightly smaller bores, we only recommend firing the 30 caliber PSR on 5.56mm muzzle mounts. It may look like a taper, but that is because the bore has a tapered lead with radii to eliminate possible erosion issues. The forward surface is a vented front support ring diameter with a. It would also be highly wishful as thermal growth would no doubt put one of the two tapers in contact at least some of the time even if there was a temperature at which the system could simultaneously interface both tapers. That would mean no running of muzzle mounts that were out of the PSR series. To put one there would mean you had to run a mount that interfaced this all the time, to prevent fouling an alignment surface. It is not uncommon for sales people to miss-speak when talking about a product. The Rock barrel OD is just kind of small for a 1/2x28 thread. 01 shim and EZ lok for a rimfire prototype that wouldn't be aligned without the shim. We had a Palmetto Rock 5.7 pistol we mounted using a single. 0475" a side on the barrel shoulder and 100% index of the shoulder inside the mount. That essentially promotes square a lot better than. 01" shims on the shoulder (the shims from us are. 035" minimum IMO, which is just an opinion.Īlso one known trick to get some shoulder back, is to put a pair of. 0275" per side to interface, where it would be nice to have. 032 Corner radius turning tool and sometimes don't cut a thread relief. 6005 diameter you are showing that we are eating up with stuff that doesn't interface the shoulder, because that clearance is necessary on some barrels, where production companies use a. ![]() ![]() 015 chamfer or so also doing part of that function, so that's. 515" counterbore on the muzzle device to get over tool nose radii, and typically a. If you can mount a normal silencer functionally on the shoulder you have, ours should work. I don't have a lot of experience with pencil barrels. The barrel diameter isn't the issue, it's the shoulder diameter vs the thread, creating whatever geometry will face on face index. PSR silencer links under the "Muzzle devices supported" section doesn't list any compatible muzzle devices other than the PSR™ DUAL-LOK™ 2 Port Muzzle Brake and PSR™ DUAL-LOK™ Flash Hider however under the DUAL-LOK Bayonet muzzle devices, the descriptions indicate that they are compatible with the PSR line of silencers and would also seem to indicate that the other DUAL-LOK muzzle devices below 2.545" OAL would also work with the PSR line. Lastly a ~0.625" OD behind a ~0.740" OD shoulder for 308? ( I assume it's ok since it meets thread shoulder min) What about a ~0.500" OD behind a ~0.615" thread shoulder OD for 5.56? ( I assume it's ok since it meets thread shoulder min) Would 0.600" be ok as the minimum thread shoulder OD (for the bayonet flash hider, 1/2x28, 5.56)? I think we used a 12.5” rail on the 16” rifle in the video. These are related to minimum thread shoulder OD dimensions. 730” OD, and a guideline for 1/2-28 would be pencil AR, or something like ~.615” OD A guideline for a minimum for 5/8-24 would be approximately.
